WebOct 10, 2016 · CCM puts together two different modes of operation (at least in the name). Does it mean data is encrypted using counter mode and then encrypted using CBC; kind of a double encryption? Yes, kinda. With the CCM mode of operation, you authenticate your data first using CBC-MAC which is, well, basically CBC on the data to be authenticated. WebMar 22, 2013 · As we know, CCM/CCMP is an amalgamation of two modes, the AES counter mode and the cipher block chain MAC (CBC‐MAC) mode. The counter mode is used to perform encryption to guarantee data confidentiality. CBC‐MAC is used to achieve data authenticity and integrity [1–3]. CCM/CCMP is a two‐pass AE mode.
