提出了一种新的超轻量级密码Raghav。Raghav是一种基于比特明文的替换置换(SP)网络，支持128/80比特密钥调度。采用0.13微米ASIC工艺进行128bit密钥调度，仅需994.25个GE。它需要的内存也更少，即2204字节的闪存，与现有的所有S-P网络轻量级密码相比，这是更少的。本文对Raghav进行了完整的安全性分析，包括线性密码分析和差分密码分析等基本攻击。本文还讨论了零相关攻击、双群攻击、代数攻击、雪崩效应、密钥冲突攻击和密钥调度攻击等高级攻击。在该密码中，分组置换的使用有助于提高吞吐量。Raghav密码使用8比特置换和S盒，从而获得了更好的扩散机制。Raghav在24兆瓦左右的功耗非常低，这比所有现有的轻量级密码都要少。Raghav密码在所有设计指标上得分，最适合物联网等应用。
— This paper proposes a new ultra lightweight cipher RAGHAV. RAGHAV is a Substitution-Permutation (SP) network, which operates on 64 bit plaintext and supports a 128/80 bit key scheduling. It needs only 994.25 GEs by using 0.13µm ASIC technology for a 128 bit key scheduling. It also needs less memory i.e. 2204 bytes of FLASH memory , which is less as compared to all existing S-P network lightweight ciphers. This paper presents a complete security analysis of RAGHAV, which includes basic attacks like linear cryptanalysis and differential cryptanalysis. This paper also covers advanced attack like zero correlation attack, Biclique attack, Algebraic attack, Avalanche effect, key collision attack and key schedule attack. In this cipher,use of block permutation helps the design to improve the throughput. RAGHAV cipher uses 8 bit permutations with S-Box which results in better diffusion mechanism. RAGHAV consumes very less power around 24mW which is less as compared to all existing lightweight ciphers. RAGHAV cipher scores on all design metrics and is best suited for applications like IoT.
