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