Abstract: This article proposes a testing technology path aimed at design mechanisms for comprehensive verification of faults. By adopting the concept of comprehensive verification, we distill an integrated verification principle and implementation requirements based on fault injection methods. The article also presents implementation principles, processes, verification evaluation methods, and key technological connotations for application trade-offs, … Read more
Click the blue text Follow Us Introduction Current hardware security research has gone beyond the scope of “standalone cryptographic chips.” We need to examine hardware security from the perspective of open systems. Traditional hardware security mainly protects keys, while new security must protect not only keys but also software. OSR has launched the “Fundamentals of … Read more
Is there an inherent connection between passive side-channel analysis and active fault injection? Author | Shuyuan Editor | Pan Qizhi Background Introduction Side-channel analysis of cryptographic algorithms refers to the process of inferring intermediate values of cryptographic operations by collecting and analyzing the physical information leaked by cryptographic chips during computation, thereby recovering the keys. … Read more
