In this paper fault diagnosis scheme for the lightweight internationally standard block CLEFIA algorithm is proposed. The CLEFIA is a symmetric key block cipher. The symmetric key algorithm in which both the encryption and decryption use a single key. The CLEFIA provides acceptable confidentiality with low cost and compare to other algorithm like AES, DES...etc has more compact hardware implementation. The CLEFIA algorithm s-boxes are different from AES both in terms of the irreducible polynomial used and the different affine transforms used before and after the multiplicative inversion. To analyze the propagation of faults that occur during transmission due to error in s-box is detected and corrected. The fault detection is done by using parity based error detection approach. Those faults are rectified by using fault diagnosis scheme. This reduces the data corruption and increases the performance. Xilinx ISE 14.3 is used for simulation and functionality verification and Xilinx XST is used for synthesis. Implemented Zynq 7000 FPGA.
