Abstract

The invention discloses a testing method of security of a level-to-level management mode key management system. The method comprises the following steps that: security of key storage and transmission is tested during a next-level key generation process; and security of repeated generation of a next-level key by a last-level key is tested. According to the security testing method of the key management system, from two perspectives of system design and system realization, security of key storage, key transmission and key repeated generation of the key management system employing a level-to-level management mode is tested; therefore, vulnerability that maybe exists in the key management system can be reduced; and security of an intelligent card application system can be improved.

Description

technical field

[0001] The invention relates to a test technology of a key management system, in particular to a safety test method of a key management system in a hierarchical management mode. Background technique

[0002] In the smart card project, the security of the application system depends on the security of the key, and the security control and management of the key is implemented by the Key Management System (KMS).

[0003] The key management system in the hierarchical management mode mainly provides key production, storage, distribution and management services for production management and application services. Calculation rules are generated. For the relationship cards involved in the key management system of the hierarchical management mode and the relationship between each relationship card, please refer to figure 1 shown, including:

[0004] Leader card, which stores the root key component and is used to generate the root key card;

[0005] The root key car...
