摘要
目前,物联网(IoT)正在迅速扩展.然而,由于缺乏足够的安全和隐私措施,极大地影响了其可持续发展,因此轻量级分组密码的研究受到了密码学领域的广泛关注.本文提出了一种新的轻量级分组密码,设计了一种新的P置换操作,称为LRP,这种设计的目的是轻量级和快速实现密码算法.虽然许多密码算法都是采用传统的SPN结构设计的,但LRP是采用分支SPN结构设计的.与传统的轻量级分组密码算法相比,整个算法设计了新的置换层和密钥扩展算法.LRP采用新颖的设计和实现技术,在硬件上实现了高安全性和紧凑性.在最小的硬件实现中,96位密钥模式的硬件要求只有2480个等效门,表明LRP提供了足够的安全级别,以应对已知的分析,包括最近的差分攻击和线性攻击等.
Abstract
At present,the Internet of Things(IoT)is rapidly expanding.However,due to lack of sufficient security and privacy measures,its sustainable development is greatly affected,so the research of lightweight block cipher has attracted great attention in the field of cryptography.In this paper,we propose a new lightweight block cipher with a new design of P-Permutation operation named LRP,which is designed to allow lightweight and fast implementation of cryptographic algorithms.Although many cryptographic algorithms are designed employing traditional SPN structure,LRP is designed adopting the branched SPN structure.Compared with the traditional lightweight block cipher algorithm,the whole algorithm is designed with a novel permutation layer and key expansion algorithm.Adopting novel design and implementation techniques,LRP achieves both high security and compact implementation in hardware.In our smallest implementation,the hardware requirements for the 96-bit key mode are only 2480 gate equivalents.We show that LRP offers a sufficient security level against known analyses including recent differential attacks and linear attacks and so on.
