Nouns
5 senses- Block Cipher Algorithm
A family of functions and their inverses that is parameterized by a cryptographic key; the function maps bit strings of a fixed length to bit strings of the same length.
- Data Encryption Algorithm
The DEA cryptographic engine that is used by the Triple Data Encryption Algorithm (TDEA).
- Decryption
The process of transforming ciphertext into plaintext.
- Forward Cipher
One of the two functions of the block cipher algorithm that is determined by the choice of a cryptographic key. The term “forward cipher operation” is used for TDEA, while the term “forward transformation” is used for DEA.
- Key Bundle
The three cryptographic keys (Key1, Key2, Key3) that are used with a Triple Data Encryption Algorithm (TDEA) mode.
