(en) mode of operation

1. (I) /cryptographic operation/ A technique for enhancing the effect of a cryptographic algorithm or adapting the algorithm for an application, such as applying a block cipher to a sequence of data blocks or a data stream. (See: CBC, CCM, CMAC, CFB, CTR, ECB, OFB.) [RFC4949:2007]

(en) Modes of Operation

A mode of operation, or mode, for short, is an algorithm that features the use of a symmetric key block cipher algorithm to provide an information service, such as confidentiality or authentication.
