Memory security detection method and system on chip

Abstract

The invention provides a memory security detection method and a system on chip, the system on chip comprises a security policy controller and a memory to be detected, and the security policy controller comprises a detection module. The security policy controller receives a detection signal which carries a to-be-detected fault and/or an attack identifier of the to-be-detected memory, and obtains a detection algorithm corresponding to the to-be-detected fault and/or the attack identifier from the off-chip memory according to the to-be-detected fault and/or the attack identifier; and the off-chip memory stores detection algorithms corresponding to various fault and/or attack identifiers, the detection module is configured according to the obtained detection algorithms to obtain a detection circuit, and the detection circuit is utilized to judge whether the to-be-detected memory has a to-be-detected fault and/or attack. Security detection of corresponding faults and/or attacks of the to-be-detected memory is achieved, multiple complex detection circuits do not need to be deployed in the system at the same time, corresponding detection algorithms are called according to different detection signals to configure the corresponding detection circuits, power consumption is reduced, and efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of hardware security, in particular to a memory security detection method and a system on chip. Background technique [0002] With the rapid development of IoT technology, IoT devices are widely used. Users use IoT devices to make life convenient and fast. IoT devices rely on users to provide users with various services while collecting their personal information. [0003] The system-on-chip is the hardware foundation of IoT devices, and memory is an important part of the system-on-chip. If the memory fails or is attacked by hardware Trojan horses, etc., it will lead to changes in the functions of IoT devices, or leak users’ personal information, or even bring losses to users. [0004] In order to ensure the safety of the memory, it is necessary to perform memory safety testing to detect faults and give an alarm in time. Most of the traditional memory detection methods cannot be flexibly updated...

AI Technical Summary

Problems solved by technology

Most of the traditional memory detection methods cannot be flexibly updated according to different faults and / or attacks, and can only detect a certain type of fault or attack. If a detection scheme for multiple memory faults is to be deployed, the overhead of the system will be increased , high power consumption, and the simultaneous deployment of multiple detection circuits for multiple memory faults and / or attack detection is complex and difficult to manage
