Problems solved by technology

[0002] In the prior art, by backing up the contact person stored in the user's global identification card (U)SIM card to the mobile phone, and then synchronizing the contact person information to the (U)SIM card after replacing the (U)SIM card, this method It can solve the problem of contact backup, but requires manual operation by the user, which will still increase the difficulty and threshold for changing the card; at the same time, this method cannot solve other private information on the (U)SIM card except contact information (such as card Application information) security backup synchronization problem, creating difficulties for operators to promote 3G, 4G services

Abstract

The invention provides a safety transfer method, device and system for card application data. The method comprises steps that a symmetric shared secrete key Ks is generated between a (U) SIM card and a card management platform in a negotiation manner; and in the card application data transfer process, the Ks is used for encrypting to-be-sent card application data or decrypting card application data sent by the card management platform. By generating the symmetric shared secrete key between the (U) SIM card and the card management platform in a negotiation manner, safety transfer of the card application data in conditions of (U) SIM card upgrade and invariable mobile phone number can be realized, so that when the user is in the (U) SIM card upgrade and changing process, the user private information on the (U) SIM card is ensured to be safe and prevented from being tampered.

Description

technical field [0001] The invention relates to the field of electronic information security, in particular to a method, device, and system for safely migrating card application data. Background technique [0002] In the prior art, by backing up the contact person stored in the user's global identification card (U)SIM card to the mobile phone, and then synchronizing the contact person information to the (U)SIM card after replacing the (U)SIM card, this method It can solve the problem of contact backup, but requires manual operation by the user, which will still increase the difficulty and threshold for changing the card; at the same time, this method cannot solve other private information on the (U)SIM card except contact information (such as card The security backup synchronization problem of application information) creates difficulties for operators to promote 3G and 4G services. Contents of the invention [0003] The purpose of the present invention is to provide a me...
