Counter with Cipher Block Chaining-Message Authentication Code (CCM)
{"Image DocumentName": "Counter with Cipher Block Chaining-Message Authentication Code (CCM)", "Image ImageDescription": "NIST standard SP C for WiFi. variation of encrypt-and-MAC approach. algorithmic ingredients. AES encryption algorithm. CTR mode of operation. CMAC authentication algorithm. single key used for both encryption & MAC. The CCM mode of operation was standardized by NIST specifically to support the security requirements of IEEE WiFi wireless local area networks (Chapter 17), but can be used in any networking application requiring authenticated encryption. CCM is a variation of the encrypt-and-MAC approach to authenticated encryption. It is defined in NIST SP C. The key algorithmic ingredients of CCM are the AES encryption algorithm (Chapter 5), the CTR mode of operation (Chapter 6), and the CMAC authentication algorithm (Section 12.6). A single key K is used for both encryption and MAC algorithms.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
