In the previous blog post, “Embedded Security Using Cryptography”, we looked at how cryptography can be used for securing assets in embedded systems and ensure confidentiality, integrity and ...

This is an explanation of the Cryptography problem "Black Cobra Pepper" from CyLab Security Academy (formerly picoCTF). The difficulty is the second lowest. Only two files are provided: chall.py and ...

The Advanced Encryption Standard (AES) is a symmetric block cipher chosen by the U.S. government to protect classified information. AES uses 128-, 192- or 256-bit keys to encrypt and decrypt data. The ...

Advanced Encryption Standard (AES) is a widely adopted and symmetric encryption algorithm standard used while securing data. It is a cryptographic standard, which was established by the US National ...

In the field of computer technology, some topics are so frequently and fiercely disputed that they almost resemble religious feuds -- Mac vs. PC, for instance, or open source vs. proprietary software.

Data Encryption Standard and Advanced Encryption Standard sound similar, and both are examples of symmetric block ciphers. That is where the similarities end, however. DES is an outdated method of ...

Encryption and secure communications are critical to our life on the Internet. Without the ability to authenticate and preserve secrecy, we cannot engage in commerce, nor can we trust the words of our ...

It’s been quite a week in the world of cryptography. For a field in which advancements are measured in the smallest of terms and major breakthroughs can take decades, the three big news stories ...
