A High throughput architecture for IoT applications and security is the necessity of today. To secure real time applications, there is a need of fast encryption process. LEA is lightweight block cipher uses any one size of key out of three key size of 128-bit, 192-bit and 256-bit based on different level of security. LEA block size is of 128-bit. The work of this paper mainly focused on LEA-128 bit key size and have got the better results as compared to other papers available in literature. Method used to get high performance results in this work, consist of pipelined architecture which provides better throughput. Proposed work mainly focused on real time application and hence throughput is chosen as main cretaria. Proposed architecture is showing 36% more frequency and 49% more throughput. In this paper reduced clock cycle method have been used to get better performance for image encryption.
