WebIn cryptography, DES-X (or DESX) is a variant on the DES (Data Encryption Standard) symmetric-key block cipher intended to increase the complexity of a brute-force attack. The technique used to increase the complexity is called key whitening . The original DES algorithm was specified in 1976 with a 56-bit key size: 2 56 possibilities for the ... WebOct 29, 2024 · Short description: Authenticated encryption mode with resistance against nonce reuse. AES-GCM-SIV is a mode of operation for the Advanced Encryption Standard which provides similar performance to Galois/Counter Mode as well as misuse resistance in the event of the reuse of a cryptographic nonce. The construction is defined in RFC 8452.
