Side channel attack preventing algorithm applicable to full life cycle of system data

Abstract

The invention relates to a side channel attack preventing algorithm applicable to the full life cycle of system data. The algorithm comprises the steps of S1, locally performing a timing sequence attack applied to password login authentication; S2, locally performing a common computation; S3, locally performing an encryption operation; and S4, executing a defense strategy when the information datais transmitting. The algorithm has the advantages that the full life cycle system running side channel attack defense frame is built for the side channel attack that may be suffered during the full running life cycle of the system data, so that the data and system security can be ensured during the whole running cycle of the system, the data is prevented from being leaked, and thus the information security is ensured.

Description

technical field [0001] The invention relates to the technical field of computer network communication, in particular to an anti-side channel attack algorithm applicable to the whole life cycle of system data. Background technique [0002] In recent years, typical cases of side channels that have great influence in the field of computer network communication and international academic circles have emerged in an endless stream. They use different forms of side channel information to analyze the vulnerable points of the target, so as to achieve the goal of confidentiality and encryption. The purpose of obtaining and cracking. Reports on the research and technical methods of side-channel attack defense at home and abroad are also emerging. The main defense methods include: software and hardware masking technology in implementation, dynamic dual-rail circuit technology, clock scrambling technology, etc. [0003] As a cryptanalysis technique for cryptographic devices, side-channe...
