AN SCHEME TO TRANSMIT SECURE MESSAGE WITHAUTHENTICATION & INTEGRITY USING TRIPLE - EHDES

[摘要] The scenario of present day of information security system includes confidentiality, authenticity, integrity, non-repudiation. This present paper focus is enlightening the technique to secure data or message with authenticity and integrity. We kept in mind the security of transmission and capacity of channel, triple EHDES provides more complexity and enhanced security and compression with sequitur provides reduce size data or image for efficiency of communication channel. Author’s previous articles define the strength of EHDES based on variation of key, cascading of EHDES or triple EHDES makes this approach more effective and usable.
