2results about How to "Implement security testing" patented technology

The present application provides a memory security detection method and a system on chip, the system on chip includes a security policy controller and a memory to be detected, and the security policy controller includes a detection module. The security policy controller receives a detection signal, the detection signal carries the fault to be detected and / or attack identification of the memory to be detected, obtains a detection algorithm corresponding to the fault to be detected and / or attack identification from an off-chip memory according to the fault to be detected and / or attack identification, the off-chip memory stores a variety of detection algorithms corresponding to the fault and / or attack identification, configures the detection module according to the obtained detection algorithm to obtain a detection circuit, and uses the detection circuit to determine whether the memory to be detected has a fault to be detected and / or an attack. To achieve security detection of the corresponding fault and / or attack of the memory to be detected, there is no need to deploy multiple complex detection circuits in the system at the same time, and the corresponding detection circuit can be configured by calling the corresponding detection algorithm according to different detection signals, thereby reducing power consumption and improving efficiency.
