Message Authentication Code MAC Part 1 | IIT Lecture Series
 
15:36
In cryptography, a message authentication code (MAC), sometimes known as a tag, is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed. The MAC value protects both a message's data integrity as well as its authenticity, by allowing verifiers (who also possess the secret key) to detect any changes to the message content.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In information security, message authentication or data origin authentication is a property that a message has not been modified while in transit (data integrity) and that the receiving party can verify the source of the message. Message authentication does not necessarily include the property of non-repudiation. Message authentication is typically achieved by using message authentication codes (MACs), authenticated encryption (AE) or digital signatures. Some cryptographers distinguish between "message authentication without secrecy" systems -- which allow the intended receiver to verify the source of the message, but don't bother hiding the plaintext contents of the message -- from authenticated encryption systems. A few cryptographers have researched subliminal channel systems that send messages that appear to use a "message authentication without secrecy" system, but in fact also transmit a secret message.

Symmetric Key and Public Key Encryption
 
06:45
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.

How to achieve integrity and authenticity with Message Authentication Code MAC ?
 
03:17
The protocol for generating and verifying a message authentication code MAC is based on a secret key k shared by the sender and the recipient and is performed using a cryptographic algorithm A. The sender sends not only the bare message m, but follows the message with its corresponding message authentication code MAC. The MAC is computed from the common algorithm A with the secret key k, as follows: MAC=A_k(m) The system does not prevent Mr. X from altering the original message m and its MAC to the new message m' and its corresponding message authentication code MAC'. Now it is the recipient's turn to act. He very much wants to know whether the message received is the one that was sent. In order to check this, he simulates the sender's procedure. He applies the algorithm A with key k to the received message m' and verifies whether the result coincides with the received message authentication code MAC'. If A_k(m') is not equal to MAC', then the recipient knows for certain that something has happened ! and he consequently does not trust the message and reject it. If, however, A_k(m') is equal to MAC' then he reasonably certain that the message was not changed. Of course, this certainty relies heavily on the strength of the cryptographic algorithm A and the number of possible keys. Let us keep in mind the underlying philosophy: Mr. X's deception is foiled since he must find the corresponding message authentication code MAC for his message m', which he cannot do because he does not know the secret key k. The mechanism of the MAC is a tool for achieving message integrity and message authenticity. If the verification works, then the recipient also know that the message is authentic because the sender is the only other person who knows the secret key k.

When there is trust issues between sender and receiver, something more than authentication is needed. The most attractive solution to this problem is the Digital Signature. The digital signature must have the following properties: It must verify the author and date and time of the signature. It must authenticate the contents at the time of the signature. It must be verifiable by third parties, to resolve disputes. Approaches of Digital Signature - RSA approach DSS / DSA approach
