An Enhanced Data Security Method Using MIPS Encryption Algorithm (MEA)
نویسنده
چکیده
The MEA is an integral approach of block cipher and transposition cipher method. It takes 64 bit plain text input and produces 64 bit cipher text as in IDEA [13] with modified key schedule to avoid possibilities of weak keys. It further makes transposition of the 64 bit cipher text to 128 bit end cipher text for disk storage. The increased length of end cipher text is a trade-off between the degree of increased security to SI and the nominal cost of storage media in the present state_of_the_art development.
