Abstract:
In computer and network systems, the private
access systems use cryptosystems that provide to certain and
ensure data of information that are authentic and secure. This
paper will develop the secure bank transaction system to
provide authentication , non-repudiation and integrity of
message using with Public key digital signature algorithm.
Digital Signature Algorithm (DSA) is used for key generation,
signature generation and signature verification. In signature
generation, the input message is hashed with secure hash
algorithm -1(SHA-1) and produces 160 bits of message digest
output. The hash value and customer’s private key operate in
digital signature algorithm and then generates digital signature.
These signature and message are sent to bank through the
network. In signature verification, the received message is
hashed with SHA-1. The hash value, received digital signature
and customer’s public key operate in DSA algorithm and
produce signature, If the two signatures are the same, the
signature is verified.
