Abstract

The invention relates to a method and a system for three-in-one smart card anti-side-channel-attack protection. According to the method and the system of the invention, a security control center is arranged in a COS layer so as to configure and manage anti-attack strategies of a chip layer, the COS layer and an application layer in a unified mode. A legitimate user can configure the security control center through a user security configuration interface after PIN verification so as to realize flexible and unified three-in-one anti-attack strategy management. By adopting the method and the system of the invention, the overall security of smart cards can be promoted, and the difficulty for smart cards to resist side channel attack is increased.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a smart card trinity anti-side channel attack protection method and system. Background technique [0002] With the rapid development of information technology and the increasing popularity of smart cards, the application of smart cards has spread across all aspects of people's lives. Smart card (smart card) is also called integrated circuit card, that is, IC card (integrated circuit card). It has features such as convenience and safety. In order to protect the security of information and communication on the smart card, a variety of encryption algorithms are implemented on the smart card. Encrypting the smart card is one of the means to effectively ensure the security of the smart card. Commonly used algorithms include DES and AES for symmetric encryption, RSA and ECC for asymmetric encryption, and SHAx series and MAC for calculating message digests. T...
