Abstract

The invention discloses a safe deactivation method and system for an embedded intelligent card, and a card management server for safe deactivation of an embedded intelligent card. The safe deactivation method for an embedded intelligent card comprises the steps that: after interactive authentication between a card management server and an embedded intelligent card succeeds, the card management server sends a deactivation command to the embedded intelligent card and receives a deactivation operation result returned from the embedded intelligent card, and updates the state information, of the embedded intelligent card, recorded by the server according to the deactivation operation result. The deactivation process is performed after the legal identities of two parties are determined through interactive authentication between the card management server and the embedded intelligent card, so that the safety for deactivation of the embedded intelligent card can be guaranteed and failure, for terminal data transmission, caused by a malicious deactivation command can be avoided.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a method, system and card management server for safely deactivating an embedded smart card. Background technique [0002] The Internet of Things is called the third wave of the world's information industry after computers and the Internet, and represents the development direction of the next generation of information technology. M2M ((Machine-To-Machine, machine-to-machine) applications are the foundation of the Internet of Things. Due to the large difference between the application characteristics of M2M and the application characteristics of the personal communication field, the traditional pluggable SIM (Subscriber Identity Module, customer identification module or smart card) Cards can no longer meet the needs of M2M applications. Embedded SIM cards (embeddedSIM, eSIM) have gradually become an authentication tool for terminals in M2M applications to access operator netwo...
