基于后量子密码算法的安全SoC芯片设计

后量子密码算法已经成为当前安全领域的研究热点。本文通过对NIST后量子密码算法竞赛候选的Saber算法进行研究,提出一种基于后量子密码算法的安全SoC芯片设计方案。该方案首先分析算法的硬件架构,优化矩阵运算和数值拼接等操作提升硬件效率,采用二次验证方式加强算法解密过程的安全性;然后,设计Hash随机数拓展生成模块、加解密模块和数据存储器以及随机数种子生成器,完成Saber算法的硬件IP核;其次,在RISC V处理器、总线和接口电路的基础上,结合时钟门控技术降低功耗,设计基于后量子密码算法的安全SoC芯片。实验结果表明,所设计的安全SoC芯片面积为2.6 mm^(2),等效逻辑门数为90k,芯片内核面积占比为75.2%,PAD面积占比为24.8%,芯片功耗为9.467 mW。

Navigating the Quantum Threat Landscape: Addressing Classical Cybersecurity Challenges

This research paper analyzes the urgent topic of quantum cybersecurity and the current federal quantum-cyber landscape. Quantum-safe implementations within existing and future Internet of Things infrastructure are discussed, along with quantum vulnerabilities in public key infrastructure and symmetric cryptographic algorithms. Other relevant non-encryption-specific areas within cybersecurity are similarly raised. The evolution and expansion of cyberwarfare as well as new developments in cyber defense beyond post-quantum cryptography and quantum key distribution are subsequently explored, with an emphasis on public and private sector awareness and vigilance in maintaining strong security posture.
