Block ciphers are invertible symmetric key cryptographic algorithms. Here, symmetric means that the same cryptographic key is used to both encrypt and decrypt messages. The key is used to transform ...

Cipher block chaining (CBC) is a mode of operation for a block cipher-- one in which a sequence of bits are encrypted as a single unit, or block, with a cipher key applied to the entire block. Cipher ...

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 ...

Ofer A. Lidsky is an entrepreneur with over 30 years of experience and is the founder and CEO of Excellent Brain. In today’s digital age, data encryption is vital for protecting sensitive information.

In my blog “The Importance of Memory Encryption for Protecting Data in Use,” I discussed the growing industry consensus on the imperative of incorporating memory encryption in computing architectures.
