Since block ciphers can only be composed of 128-bit blocks, they must break up the message into several blocks and encrypt each one individually.

Most encryption algorithms use the block cipher method, which codes fixed blocks of input. Others use the stream method, which encrypts one bit at a time.

The block ciphers, dubbed SIMON and SPECK, are intended to be a lightweight, low-power-using alternative to existing encryption systems available for RFID tag reads. The name SIMON alludes to the ...

The algorithm expands a single message by up to 8 bytes. DES is a block cipher that encrypts data in blocks of 64 bits. SAS Proprietary This provides basic fixed encoding encryption services on all ...

Encryption The "Cryptography" section of the docs starts like this: All symmetric cryptographic operations are based on AES-128. It operates in cipher block chaining mode for the file and folder ...

- Japan's only 128-bit block cipher encryption algorithm to be adopted - The selection is attributed to Camellia's high reputation for ease of procurement, and security and performance features ...

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.

The creators of banking trojan programs in Brazil are using sophisticated block ciphers to encrypt their malware, making detection by anti virus products more difficult.

The new SCARF model uses block cipher encryption, a completely new idea for the field, according to the researchers. "Normally, we encrypt data with 128 bits, in the cache we sometimes work with ...

Camellia, which also was selected for the original list, was reselected as the only Japanese encryption algorithm among 128-bit block ciphers. Significance of the adoption - Safety and performance An ...
