Introduction
Security chip is an important basic security function unit, which is widely used in various information products and systems. The security chip in this document refers to the integrated circuit chip which implements the function of cryptographic algorithm and directly or indirectly adopts cryptographic technology to process keys and sensitive information.
Based on the cryptographic algorithm implemented, the security chip must meet various security capabilities according to different designs and applications. This document divides security capability into nine parts: cryptographic algorithm, security chip interface, key management, sensitive information protection, security chip firmware security, operating mechanism, protection security, audit and lifecycle security. Each security capability is classified into five security levels according to different security requirements, and each security level is required to increase step by step.
In order to provide the intended security service, the security level of the deployed security chip shall adapt to the application and environmental security requirements, so as to ensure that the information products and systems using the security chip establish a security foundation from the chip level.
This document is applicable to cryptography test of security chips, and may also serve as a guide for the development of security chips and as a reference for selecting security chips that meet the requirements of application and environment security.
