轻量级密码学是一个有趣的领域，它在提供安全性、更高的吞吐量、低功耗和紧凑性方面取得了完美的平衡。近年来，许多紧凑型算法，如PRESENT、CLEFIA、SEA、TEA、LED、ZORRO、Hummingbird和KANTAN，已经成为轻量级加密引擎。本文提出了一种新的轻量级紧凑加密系统的设计基于位置换指令组操作（GRP），这是广泛研究和广泛研究。使用PRESENT的S盒，我们已经为GRP添加了混淆属性，因为所有使用位置换指令的现有算法都不具有此混淆属性。通过比较现有的紧致算法及其密码分析的S盒，本文提出了一种新的混合系统，提供了更紧凑的结果在存储空间和门等效。设计并实现了一种由GRP和PRESENT的S盒组成的混合密码体制。这种融合产生了一种轻量级密码，这是迄今为止在内存需求方面最紧凑的实现。我们已经在LPC2129处理器上测试并验证了这一点。设计和分析了最近使用的轻量级算法（如PRESENT和CLEFIA）的各种S盒，以创建一个完美的融合，该融合应该能够抵抗攻击。使用PRESENT的S盒，有助于进一步降低门的复杂性。这种混合模型的结果是2125门等效，这比其他轻变体模型，如DESXL，CLEFIA和AES更好。此外，GRP特性不仅对获得期望的雪崩效应非常有帮助，而且还因为它导致在硬件中的紧凑实现。本文提出了一种新的方法，将在轻量级加密协议领域产生积极的影响。
Lightweight cryptography is an interesting field that strikes the perfect balance in providing security, higher throughput, low-power consumption, and compactness. In recent years, many compact algorithms like PRESENT, CLEFIA, SEA, TEA, LED, ZORRO, Hummingbird, and KANTAN have made the mark to be used as lightweight crypto engines. In this paper, we present the design of a new lightweight compact encryption system based on bit permutation instruction group operation (GRP), which is widely studied and extensively researched. Using the S-box of PRESENT, we have added the confusion property for GRP, because all the existing algorithms using bit permutation instructions do not have this confusion property. By comparing the existing S-boxes of compact algorithms and its cryptanalysis, a new hybrid system is proposed in this paper that provides more compact results in terms of both memory space and gate equivalents. A hybrid cryptosystem, which consists of GRP and S-box of PRESENT, is designed and implemented on a 32-bit processor. This fusion has resulted in a lightweight cipher that is the most compact implementation, till now, in terms of memory requirement. We have tested and verified this on an LPC2129 processor. Various S-boxes of recently used lightweight algorithms, such as PRESENT and CLEFIA, are designed and analyzed to create a perfect fusion that should be resistant to attacks. Using the S-box of PRESENT, it helps in further reducing the gate complexity. This hybrid model results in 2125 gate equivalents, which is better than other light variant models like DESXL, CLEFIA, and AES. Moreover, GRP properties are very helpful not only to attain the desired avalanche effect, but also as it results in a compact implementation in hardware. This paper proposes a novel approach that will have a positive impact in the field of lightweight encryption protocols.
