Describe the role of hash functions in authenticating message? How SHA-1 algorithm is used to produce hash value of a message? Explain.[10]
A hash function H is a mathematical function that maps a variable-length input message M to a fixed-length output called the message digest or hash value. The basic authentication process works as follows: At the Sender Side: 1. Sender computes hash value: h = H(M) 2. Sender transmits the message...
