Generalized Feistel Network block cipher security relies on a flawed assumption: a new IACR preprint shows that adding more ...

Zero-correlation linear cryptanalysis is an important method to analyze the security of block ciphers. But there are few works on zero-correlation linear attacks combined with the related-key setting.

The National Security Agency (NSA) is offering two families of encryption algorithms, known as block ciphers, intended to provide a level of security for such processes as authentication or ...

This is the age where technology is expected to do more, faster, anonymously, and often invisibly. And it’s supposed to use less power, with smaller footprints, unobtrusively and intuitively. And all ...

You probably use encryption, in one form or another, every day. You might not know that you are, but you are. And my guess is that you don’t give it a second thought. Do you have a subscription based ...

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 ...
