E is the MAC function. Message and MAC will be sent to the receiver.MAC can be of any size, sometimes hash function isused in place of authentication scheme to fix the size.In order to identify the problem with MAC,timestamp and message sequence number arerequired. Various methods are ...

In this brief paper, we introduce encryption-free message authentication based entirely on fast one-way hash functions. Two methods are presented and their strength is analyzed. The security of the proposed methods is based on the strength of the underlying one-way hash function....
We present new, simple, and practical constructions of message authentication schemes based on a cryptographic hash function. Our schemes, NMAC and HMAC, are proven to be secure as long as the underlying hash function has some reasonable cryptographic strengths. Moreover we show, in a quantitativ...
The wireless device obtains the input message. The wireless device generates a keystream. The wireless device computes a message authentication code using the keystream and a universal hash function. The universal hash function is computed using carryless multiplication....
Hash-based Message Authentication Code (HMAC) is a type of message authentication code involving a cryptographic hash function and a secret cryptographic key.
Hash-based message authentication code (or HMAC) is a cryptographic authentication technique that uses a hash function and a secret key. With HMAC, you can achieve authentication and verify that data is correct and authentic with shared secrets, as opposed to approaches that use signatures and asy...
