Nouns
6 senses- Cipher Block Chaining-Message Authentication Code
A secret-key block-cipher algorithm used to encrypt data and to generate a Message Authentication Code (MAC) to provide assurance that the payload and the associated data are authentic.
- Counter with Cipher Block Chaining-Message Authentication Code
A mode of operation for a symmetric key block cipher algorithm. It combines the techniques of the Counter (CTR) mode and the Cipher Block Chaining-Message Authentication Code (CBC-MAC) algorithm to provide assurance of the confidentiality and the authenticity of computer data.
- Formatting Function
The function that transforms the payload, associated data, and nonce into a sequence of complete blocks.
- Mode of Operation
An algorithm for the cryptographic transformation of data that features a symmetric key block cipher algorithm.
- Payload
The input data to the CCM generation-encryption process that is both authenticated and encrypted.
- Valid Data Element
A payload, an associated data string, or a nonce that satisfies the restrictions of the formatting function.
