Abstract – Lightweight encryption is an interesting field that strikes the perfect balance in providing security, low-power consumption, and compactness. In this paper, we present the design of a lightweight encryption based on the grouping permutation(GRP).In the s-box we have added the confusion property for GRP.The existing S boxes with DESXL, CLEFIA, and AES algorithms are compared and a new lightweight encryption system is proposed in this paper that provides compact results which reduces gates and memory size.GRP not only adds strength to the cipher it also reduces the power consumption and memeory requirements.By using the S box of PRESENT the gate complexity is reduced.A lightweight S box that can be mapped into the GRP to have efficient cryptographic structure and to strengthen the security.
