Abstract:
Today’s connected society requires secure information
system to preserve data privacy and authentication un critical
applications. This paper intends to implement secure
information system for critical applications. The triple Data
Encryption Standard (Triple-DES) algorithm has emerged to be
the most commonly used in varying application because it is still
reasonably secure. Diffie-Hellman key exchange (D-H) is a
cryptographic protocol that allows two parties that have no
prior knowledge of each other to jointly establish a share secret
key over an insecure channel. This can then be used to encrypt
subsequent communications using a symmetric key cipher. The
main objective of this paper is to provide an Information
Security Enhancement System by taking the advantages of
Triple-DES cryptographic algorithm and D-H key exchange
protocol to enhance security for information, and evaluate the
Triple-DES execution times of encryption and decryption on the
various data sizes.
