Abstract

The invention discloses a cipher chip embedded application installation method and device. The method comprises the following steps: when a user triggers an application installation operation, performing identity authentication on the user; after the authentication is passed, receiving a preset first metric value of the to-be-installed embedded application input by the user; receiving the to-be-installed embedded application and an application installation package of the to-be-installed embedded application; performing integrity measurement on the to-be-installed embedded application installation package to obtain a second measurement value; and when the first metric value of the to-be-installed embedded application is equal to the second metric value of the to-be-installed embedded application, installing the application installation package of the to-be-installed embedded application. The technical problem that potential safety hazards exist when a third-party application is installed on a cipher chip is solved. The security of installing the third-party application on the cipher chip is improved.

Description

technical field [0001] The invention relates to the technical field of application installation, in particular to a method and device for installing an embedded application of a cryptographic chip. Background technique [0002] A cryptographic chip refers to an integrated circuit chip that implements one or more cryptographic algorithms and uses a cryptographic system to protect keys and sensitive information. The core of a cryptographic chip is usually an intelligent CPU chip that can run cryptographic algorithms. At present, cryptographic chips have been widely used in government affairs, finance, public security, national defense, civil affairs, communications, transportation, health, education, logistics, water, electricity and other fields. The core foundation of information system security. [0003] With the widespread use of encryption chips, encryption chips must be adapted to various scenarios. Therefore, multiple third-party applications may be installed on one e...
