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 ...

The arena of creating secure environments in the hardware and software industries is somewhat shrouded in mystery and misunderstanding. Certainly, some types of ciphers are relatively straightforward ...

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.

Introduction to ciphers and substitution. Alice and Bob and Carl and Julius: terminology and Caesar Cipher ; The key to the matter: generalizing the Caesar Cipher ; Multiplicative ciphers ; Affine ...

In today's electronic age, the importance of digitalcryptography in securing electronic data transactions isunquestionable. Every day, users electronically generate andcommunicate a large volume of ...

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 ...

A formula used to turn ordinary data, or "plaintext," into a secret coded message known as "ciphertext." The ciphertext can reside in storage or travel over unsecure networks without its contents ...

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 ...
