Applying Java’s Cryptography
 
58:54
Learn how to control Java’s cryptographic features to protect your application and any data that you manage. This session explains what different cryptography features do, what threats are addressed by each feature, and where the configuration takes place. Topics include certificates, code signatures, authenticating dynamic JVM languages, TLS control, perfect forward security, and transparent JPA encryption. Author: Erik Costlow Erik Costlow is a product manager in Oracle's Java Platform Group and a regular contributor to the Java Platform Group PM blog. Erik also works closely with industry on Oracle's Java Root Certificate Program to ensure highest program quality.

Cryptography is a complex and confusing subject. In this talk you will learn about the core components of cryptography used in software development: securing data with encryption, ensuring data integrity with hashes and digital signatures, and protecting passwords with key derivation functions. While learning how to use these components, you will also learn the best practices that drive strong cryptography. This talk won’t make you a cryptography expert but it will give you the knowledge necessary to use cryptography properly. No prior knowledge of cryptography is required for this presentation.

How to Use Java Cryptography API Securely
 
41:14
Mansi Sheth, Security Researcher, Veracode Inc Are you overwhelmed by the overabundance of choices provided by the Java Cryptography API when choosing an encryption algorithm? Are you on top of all the latest happenings in cryptographic communities and know which cryptographic primitives can be broken and how? Due to time constraints, do you find yourself copy/pasting from the internet, hoping and praying that it’s secured? If any of your answers are “yes,” come to this session. It goes over all cryptographic primitive: RNGs, encryption/decryption algorithms, HMACs, and so on. The presentation points out areas that require careful attention, helps you make correct algorithmic and keying material choices, and provides plenty of code examples showing correct and incorrect usages.

Cryptography for Programmers - Daniel James [ACCU 2018]

WE ARE SORRY FOR THE POOR AUDIO IN THIS TALK, THE MIC FAILED AT THE START OF THE TALK LEAVING ONLY THE ONBOARD CAMERA AUDIO - WE HAVE TRIED TO CLEAN IT UP AS BEST WE CAN. In an increasingly hostile world security is becoming more and more important in today’s software design. Increasing regulation also means that security measures are mandated in the design of new software. Many programmers, however, are unfamiliar with security concepts and jargon, and find the learning curve challenging. This talk will give an introduction to cryptographic techniques and an overview of the use of cryptography in software. It is aimed at programmers, not at mathematicians or at cryptographers. The talk will be language-agnostic, but will include some discussion of common cryptographic APIs, which are typically written to be C-callable.

RuhrSec 2017: "How to Build Hardware Trojans", Prof. Dr. Christof Paar
 
44:45
Countless systems ranging from consumer electronics to military equipment are dependent on integrated circuits (ICs). A surprisingly large number of embedded systems are already security-critical, e.g., medical devices, automotive electronics, SCADA systems or network routers. If the underlying ICs in an applications are maliciously manipulated through hardware Trojans, the security of the entire system can be compromised. In recent years, hardware Trojans have drawn the attention of governments and the scientific community. Even though hardware Trojans have been studied over the last 10 years or so, little is known about how they might look, especially those that are particularly designed to avoid detection. In this talk we introduce several approaches with which a sophisticated attacker could insert Trojan into hardware platforms. We will look at hardware Trojans realized on both, ASICs (application specific integrated circuits) and FPGAs, i.e., programmable hardware.

AES Encryption 1: Intro and Outline

Today we'll begin looking at the most widely used data encryption in the world, the AES Encryption Algorithm! It's a symmetric key encryption algorithm. It scrambles data so you can securely store sensitive information on drives or USB's or transfer data over a network. Over the course of the next videos in this series, we'll drill down and examine exactly how the algorithm works. I hope to present it in such a way that you could encrypt data with a pen and paper!
