摘要: We present a new message authentication code (MAC) called the cyclic redundancy check-noise-tolerant (CRC-NTMAC). The CRC-NTMAC improves upon recently developed NTMAC. Unlike conventional MACs, such as keyed-hash MAC (HMAC), and NTMAC tolerate modest number of errors, might be caused by noisy communications channel. Furthermore, both MACs provide estimates locations errors. CRC-NTMAC, however, provides better has lower false acceptance probability. is also not based on cryptographic hash functions
