Authentication protects two parties from the third party, but not protect against each other. Digital signature verification of the message source, protects the authority from anyone.
This paper proposes a solution for digital signature generation to digitally signing an submitted request to library website using the one time pad( OTP). In this paper, we focus our attention on decreasing the electronic requests security vulnerability by securing requests using an approximate one-time pad. A one-time pad, considered to be the only perfectly secure cryptosystem, secures an electronic request message for transport over any medium. The keys generated from request information using proposed hash algorithm deal with multiple parameters each one has multi state (0,1,2,3) as input and output hashed key of (0..9) state.
