六、内容简介：

Side-Channel Analysis (SCA), a non-invasive technique, proves highly effective in scrutinizing vulnerabilities in the implementation of cryptographic algorithms by analysing the Physical Information Leakage (PLI), such as power dissipation and electromagnetic emanation. These leakages often expose critical information, including encryption/decryption keys, which are pivotal for cryptographic algorithms. To mitigate the risk of key leakage, a range of side-channel countermeasures, categorized as Masking and Hiding countermeasures, have been developed to impede SCA and safeguard cryptographic circuits. In this talk, I will introduce several novel SCA techniques to evaluate cryptographic circuits secured with two widely utilized countermeasures -- Masking and Hiding. Thereafter, I will present the Dual-Hiding SCA countermeasures based on asynchronous logic.  Asynchronous logic-based SCA countermeasures naturally introduce both Vertical and Horizontal Hiding countermeasures to produce highly randomized patterns in PLI waveforms, significantly increasing the side-channel security level of cryptography devices.
