Method and system for remotely downloading authentication application certificate

Abstract

The invention provides a method and system for remotely downloading an authentication application certificate. The method comprises the following steps of: establishing a secure channel with a secure routing network element (SM-SR) of a contract relation management platform; sending an authentication application certificate application request to the SM-SR by using the secure channel; receiving an authentication application certificate response message sent by the SM-SR through the secure channel, wherein the authentication application certificate response message carries the authentication application certificate; and extracting and storing the authentication application certificate from the authentication application certificate response message. The method and the system can solve the problems that an existing private solution based on an intelligent card usually needs to cooperate with a specified card provider and an operator, need to preset a specified authentication application and sensitive data such as a certificate, a secret key and the like during card making, is only suitable for users in a specific range, and cannot download the authentication application certificate remotely in real time.

Description

technical field [0001] The invention relates to the technical field of smart cards, in particular to a method and system for remotely downloading authentication application certificates. Background technique [0002] As the country accelerates the pace of "new infrastructure", 5G communication networks will increasingly be integrated into all aspects of social management. A series of 5G application scenarios all put forward higher requirements for information security than the traditional Internet, especially in the field of industrial Internet of Things, where a large number of diverse terminals in ubiquitous connection scenarios are easy to be attacked and exploited, posing a threat to network operation security. Due to differences in terminal capabilities Very large, due to the limited resources and capabilities of weak terminals, the terminal's own security protection capabilities are also weak, and it is easy to become an object of attack and control. On the other hand...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a method and system for remotely downloading authentication application certificates to solve the existing private solutions based on smart cards. In cooperation with suppliers, it is necessary to pre-set sensitive data such as designated authentication applications and certificates and keys when making cards, which can only be applied to users within a specific range, and cannot remotely download authentication application certificates in real time.
