You plan to use salt to defeat dictionary attack against an pair, in a computer system that uses a very simple hash in the authentication process = <11111, 11011 >.
Possible length of salt = 3.
The hash is computed by binary addition of salt to the password, and then keeping only the last four bits of the result of the binary addition. The system stores triples of.
Your answer must have three parts: What are the possible values of salt?, What is the hash of password + salt for salt =110? Explain the protocol for Authentication.
