High-Performance FPGA Implementations of Lightweight ASCON-128 and ASCON-128a With Enhanced Throughput-to-Area Efficiency [PDF]
2024 17th International Conference on Information Security and Cryptology (ISCTürkiye)The ASCON algorithm was chosen for its efficiency and suitability for resource-constrained environments such as IoT devices. In this paper, we present a high-performance FPGA implementation of ASCON-128 and ASCON-128a, optimized for the throughput-to ...

Cryptanalysis of round-reduced ASCON
Science China Information Sciences, 2016ASCON是CAESAR竞赛的候选认证加密算法之一。在CT-RSA 2015上, 其设计者恢复了含有6轮初始化阶段的ASCON算法的密钥, 并给出了3/4轮的标签生成阶段的伪造攻击, 该伪造需求2^33/2^101个消息。这篇论文对包含7轮初始化阶段和5轮明文处理阶段的简化版ASCON算法执行密钥恢复攻击。除此之外, 我们对4/5/6轮的标签生成阶段建立了伪造, 所需数据量为2^9/2^17/2^33。该伪造相对之前具有实际攻击复杂度。

We present a detailed security analysis of the CAESAR candidate Ascon. Amongst others, cube-like, differential and linear cryptanalysis are used to evaluate the security of Ascon. Our results are practical key-recovery attacks on round-reduced versions of Ascon-128, where the initialization is reduced to 5 out of 12 rounds.
