Symmetric Key and Public Key Encryption
Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

Security Policy and Enterprise Key Management To centrally Manage Encryption Keys from Vormetric
This is an excerpt of Vormetric's whitepaper: Simplifying IT Operations Securing and Controlling Access to Data Across the Enterprise. http://www.Vormetric.com/key82 .The whitepaper outlines the challenges of enterprise key management and details ways to minimize the risk. This whitepaper from Vormetric on Key management strategy strives to provide the reader with an understanding, of the importance of encryption key management and of its evolution. Additionally, understanding that companies today require actionable information, the paper provides the reader with a set of criteria for encryption key management as well as an understanding of the challenges that may be faced. This is followed by a review of the recent industry initiatives and compliance regulations that are shaping the future of key management strategy. Lastly, the paper describes Vormetric's Key Management, a component of the Vormetric Data Security product family. According to the whitepaper, encryption key management should meet four primary criteria: 1. Security -- In implementing a comprehensive data security strategy, organizations are well - advised to consider the security of the encryption keys. Where are they stored and how are they protected? Improper key management means weak encryption, and that can translate into vulnerable data. 2. Availability -- In addition to being secure, the keys must ensure that the data is available when it is needed by the system or user. Key management practices that add complexity can decrease availability or add overhead to the network. That results in damage to the over efficiency of the network. 3. Scalability and Flexibility -- Growth and change are inevitable in an organization. The key management solution should be able to address heterogeneous, distributed environments so as not to hamper either growth or change. 4. Governance and Reporting -- Reporting is essential to proper institutional governance. Often, third party entities (be they customers or regulatory authorities) will request, and in some cases mandate, proper governance and reporting of key management. That means implementing and enforcing things like separation of duties, authorization process and key lifecycle management.

Secure Overlay Routing Using Key Pre-Distribution: A Linear Distance Optimization Approach

Mobile: (0) 9952649690, Email: [email protected], web: http://www.jpinfotech.org, Blog: http://www.jpinfotech.blogspot.com Key pre-distribution algorithms have recently emerged as efficient alternatives of key management in today’s secure communications landscape. Secure routing techniques using key pre-distribution algorithms require special algorithms capable of finding optimal secure overlay paths. To the best of our knowledge, the literature of key pre-distribution systems is still facing a major void in proposing optimal overlay routing algorithms. In the literature work, traditional routing algorithms are typically used twice to find a NETWORK layer path from the source node to the destination and then to find required cryptographic paths. In this paper, we model the problem of secure routing using weighted directed graphs and propose a boolean linear programming (LP) problem to find the optimal path. Albeit the fact that the solutions to boolean LP problems are of much higher complexities, we propose a method for solving our problem in polynomial time. In order to evaluate its performance and security measures, we apply our proposed algorithm to a number of recently proposed symmetric and asymmetric key pre-distribution methods. The results show that our proposed algorithm offers great network performance improvements as well as security enhancements when augmenting baseline techniques.

#EOSHackathon TelEOS -  decentralized messenger with end-to-end encryption.
Blockchain Lab is the team of professionals working with bitcoin from 2013. Our key competences are smart contracts and blockchain solutions development and consulting. This April in partnership with Cryptolions.io we have organized the first in Ukraine EOS-meetup and now we are creating EOS-community in Eastern Europe. We are happy to present our idea TelEOS - decentralized messenger with end-to-end encryption. End-to-end encryption is a system of communication where only the communicating users can read the messages. In principle, it prevents potential eavesdroppers – including telecom and Internet providers, and even the provider of the communication service – from being able to access the cryptographic keys needed to decrypt the conversation. The systems are designed to defeat any attempts at surveillance or tampering because no third parties can decipher the data being communicated or stored. For example, companies and applications that use end-to-end encryption are unable to hand over texts of their customers' messages to the authorities. TelEOS - free and safe communication for everyone! Please, support our idea by liking this video.

Securing the Software Supply Chain with TUF and Docker
If you want to compromise millions of machines and users, software distribution and software updates are an excellent attack vector. Using public cryptography to sign your packages is a good starting point, but as we will see, it still leaves you open to a variety of attacks. This is why we designed TUF, a secure software update framework. TUF helps to handle key revocation securely, limits the impact a man-in-the-middle attacker may have, and reduces the impact of repository compromise. We will discuss TUF's protections and integration into Docker's Notary software, and demonstrate new techniques that could be added to verify other parts of the software supply chain, including the development, build, and quality assurance processes.

Philippine National Public Key Infrastructure - PNPKI
Public Key Infrastructure or PKI allows users of public networks like the Internet to privately exchange data securely. PKI is essentially a set of hardware, software, policies, personnel and procedures needed to create, manage, distribute, use, store and revoke digital certificates. Data security through the PKI is an essential component of the E-Government Master Plan and the Integrated Government Philippines (iGovPhil) Project. The PKI is one of the core services being offered by the iGovPhil project and will foster trust in the government by ensuring secure and reliable online transactions. All government online applications stand to benefit from the use of the PKI and this ultimately improves service delivery of the government to its citizens. At the heart of the PKI is the concept of digital certificates. These certificates are very small files that can be stored on your computer, an ordinary flash drive or USB token. Through the use of certificates issued and digitally signed by a Certificate Authority (CA), the PKI ensures that the sender of data is indeed the source and that the said data has not been tampered with in transit. PKI can be used to encrypt data such as email or online transactions. It will also be an integral part of iGovPhil applications, such as the Online Payment Gateway System, National Archive Records and Management System (NARMIS) and Government-Wide Email System (GovMail), that will require secure communication and encryption. If your agency uses email to communicate with other agencies and the public, or has online transactions with the public or has plans to do so, then you need PKI. Among the applications that use PKI are: Authentication in Web applications Electronic Documents and Forms Signing Virtual Private Networks (VPNs) Wireless Networks Email and Instant Messaging Some applications, such as email, are fairly easy to configure to integrate with PKI and only requires the users to register and receive their digital certificates. More complicated applications, such as that for online transactions, would require some development time. Eventually, digital certificates will be issued to private individuals to facilitate transactions with government as well as to secure their personal electronic communication. While the iGovPhil Project is already hard at work to churn out applications that take advantage of the PKI, there is still much to be done. Wouldn't it be nice if we can file our income tax returns online, bid on government procurement proceedings, apply for loans, and pay our taxes in the convenience of our home, knowing full well that our transactions are secure and tamper-proof? All these applications require the PKI and it is only a matter of time before they become a reality. Who Can Avail Government agencies and personnel Private individuals Government computers, servers and machines

CERIAS Security: Secure Network Coding for Wireless Mesh Networks 1/4
Clip 1/4 Speaker: Cristina Nita-Rotaru · Purdue University In this talk we identify two general frameworks (inter-flow and intra-flow) that encompass several network coding-based systems proposed in wireless mesh networks. Our systematic analysis of the components of these frameworks reveals vulnerabilities to a wide range of attacks, which may severely degrade system performance. We then focus on addressing the most severe and generic attack against network coding systems, known as packet pollution attack. We show that existing cryptographic mechanisms that were proposed to solve the problem have a prohibitive cost that makes them impractical in wireless mesh networks. We propose the first practical defense mechanisms to pollution attacks in network coding for wireless mesh networks. The experimental results show that the proposed mechanisms can effectively filter out polluted packets and quickly identify and isolate attacker nodes while incurring small computation and bandwidth overhead.

In a significant portion of such applications, the confidentiality and integrity of the communicated messages are of particular interest. In this work, we propose two novel techniques for authenticating short encrypted messages that are directed to meet the requirements of mobile and pervasive applications. By taking advantage of the fact that the message to be authenticated must also be encrypted, we propose provably secure authentication codes that are more efficient than any message authentication code in the literature. The key idea behind the proposed techniques is to utilize the security that the encryption algorithm can provide to design more efficient authentication mechanisms, as opposed to using standalone authentication primitives.

Virtual Proofs of Reality and their Physical Implementation
Virtual Proofs of Reality and their Physical Implementation Ulrich Rührmair Presented at the 2015 IEEE Symposium on Security & Privacy May 18--20, 2015 San Jose, CA http://www.ieee-security.org/TC/SP2015/ ABSTRACT We discuss the question of how physical statements can be proven over digital communication channels between two parties (a "prover" and a "verifier") residing in two separate local systems. Examples include: (i) "a certain object in the prover's system has temperature X°C", (ii) "two certain objects in the prover's system are positioned at distance X", or (iii) "a certain object in the prover's system has been irreversibly altered or destroyed". As illustrated by these examples, our treatment goes beyond classical security sensors in considering more general physical statements. Another distinctive aspect is the underlying security model: We neither assume secret keys in the prover's system, nor do we suppose classical sensor hardware in his system which is tamper-resistant and trusted by the verifier. Without an established name, we call this new type of security protocol a "virtual proof of reality" or simply a "virtual proof" (VP). In order to illustrate our novel concept, we give example VPs based on temperature sensitive integrated circuits, disordered optical scattering media, and quantum systems. The corresponding protocols prove the temperature, relative position, or destruction/modification of certain physical objects in the prover's system to the verifier. These objects (so-called "witness objects") are prepared by the verifier and handed over to the prover prior to the VP. Furthermore, we verify the practical validity of our method for all our optical and circuit-based VPs in detailed proof-of-concept experiments. Our work touches upon, and partly extends, several established concepts in cryptography and security, including physical unclonable functions, quantum cryptography, interactive proof systems, and, most recently, physical zero-knowledge proofs. We also discuss potential advancements of our method, for example "public virtual proofs" that function without exchanging witness objects between the verifier and the prover.
