Taking the block cipher AES as an example, the criterion nonlinearity of S-box was introduced to quantify its resistance related to linear cryptanalysis; while the differential uniformity was used ...

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.

This publication specifies the Triple Data Encryption Algorithm (TDEA), including its primary component cryptographic engine, the Data Encryption Algorithm (DEA). When implemented in an SP ...

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 ...

Block-cipher encrypted malicious links, for example, can be downloaded and analyzed, but not detected as malicious. If that happens enough, the malicious links can even become whitelisted ...

Bytes of plaintext go into the stream cipher, and bytes of encrypted text come out the other end. RC4 is an example of a stream cipher (see RC4). Contrast with block cipher.

However, the report said Adobe had used a single block cipher throughout the database, resulting in identical passwords having the same ciphertext in the database.
