摘要：Lightweight cryptography is an interesting field which provides security, higher throughput, low powerconsumption and compactness. Several algorithms like PRESENT, CLEFIA, SEA, TEA, Hummingbird and KANTANhave made the mark to be used as lightweight algorithms. In this paper, we present the design of hybrid lightweightencryption system based on bit permutation instruction GRP (group operation) and the S-box of PRESENT. A newhybrid system is proposed that provides more compact results in terms of both memory space and gate equivalents.This design has resulted in most compact implementation in terms of memory requirement. By using the S-box ofPRESENT, it helps in resistant to several differential attacks and also GRP properties are very helpful to attain thecompact implementation in hardware. The design is coded using VHDL language and implemented into the Spartan 6FPGAs.
