This project aims to design, implement and verify the first ever fully comprehensive countermeasure against simultaneous attacks on devices performing a cryptographic task, such as a smart card or a mobile phone used for an electronic payment, through a variety of side channels. Side channel attacks aim to obtain unauthorized access to secret cryptographic keys used by such devices, by collecting and statistically processing measurements of by-products of the physical operation of these devices, such as the consumed power or electromagnetic radiation. Rapid proliferation of personal devices used for electronic payments or containing sensitive data makes such a comprehensive countermeasure urgently needed.

该项目旨在设计、实施和验证有史以来第一个全面的对策，以防止通过各种侧通道同时攻击执行加密任务的设备，例如智能卡或用于电子支付的移动电话。侧信道攻击的目的是通过收集和统计处理这些设备物理操作的副产品（如消耗的功率或电磁辐射）的测量值，获得对这些设备使用的秘密加密密钥的未经授权的访问。用于电子支付或包含敏感数据的个人设备的迅速扩散，迫切需要这样一种全面的对策。
