Abstract: This work focuses on the light weight security algorithm Tiny Encryption in order to increase the speed and to reduce the hardware complexity. Algorithm TEA which can be implemented in microcontroller to adapt with many real time constraints such as memory, data loss and low cost. The additive feature of this proposed system is that it uses Key Generation Unit (KGU) to produce the random key to make it optimal for sensitive data transfer in many real-time applications. This above work uses microcontroller and the performances of this cryptosystem is analyzed by implementing the cryptographic algorithm TEA with key generation unit. The work extends with implementation of serial (UART) as mode of communication to transfer the data from encryption unit to decryption unit.
Keywords: TEA, UART.
