Hi I have a specific question regarding the COSE defined AES CCM (chapter 10.2 of RFC 8152) mode. The definition of CCM mode is referenced in RFC3610, but RFC3610 only defines 128-bit block ciphers. In Table 10 in chapter 10.2 of RFC8152 there are specified AES CCM algorithms, that uses 256-bit block ciphers like the AES-CCM-16-64-256 algorithm. Where is the CCM mode for 256-bit block ciphers defined?
Any advice would be helpful. Thanks in advance for your answer.
