Abstract:-In this paper we describe ARM Microcontroller implementations of the Data
Encryption Standard (DES) algorithm, with time-variable key technique to increase its
immunity to Cryptanalysis attack. This proposed scheme changes the key with time.
Using time-variable key technique enhances the security of DES because the same plain
text is ciphered to different cipher texts by time. Hackers will face difficulty to hack into
the proposed scheme because of time-variant behavior. This method provides more
security against cryptanalysis attack than that provided by conventional old DES
algorithm. LPC2148 ARM microcontroller was selected as the target for implementation
with the embedded C as the software programming language.
Key Words:-Cryptographic algorithm, DES, ARM Processor, Encryption algorithm, Embedded Systems and applications.
