Abstract

The invention provides a task processing method and device for preventing side channel attacks based on a heterogeneous computing system and a computer readable storage medium. The method comprises the steps of performing task division on a to-be-executed first task to obtain at least two first sub-tasks, determining a random probability number, and dynamically adjusting the at least two first sub-tasks according to the random probability number to obtain at least two to-be-executed first sub-tasks, and allocating the at least two first sub-tasks to be executed to at least one processing unitmatched with the task characteristics, and respectively executing the at least two to-be-executed first sub-tasks by the at least one processing unit corresponding to the at least two to-be-executed first sub-tasks. Through adoption of the method and the device, the side channel attack can be effectively resisted, the resource overhead is reduced, and the information security is improved.

Description

technical field [0001] The present application relates to information security technology, and in particular to a task processing method and device for preventing side channel attacks based on a heterogeneous computing system, and a computer-readable storage medium. Background technique [0002] With the development of information technology, problems related to information security emerge in endlessly. Among them, side channel attacks have become a major problem in information security. In order to solve the problems of information leakage and information cracking under side channel attacks, the existing technology mainly protects from two aspects: software and hardware: the software considers the possibility of leakage, and uses encryption algorithms to ensure information security even under side channel attacks; In terms of hardware, redundant information is added to blur the physical information of signal jumps during task execution, so that attackers cannot obtain enou...
