A method for replacing at least one authentication parameter for authenticating a secure element,

摘要

The present invention relates to a method of replacing at least one authentication parameter for authenticating a security element cooperating with a terminal, the authentication parameter allowing an authentication system of a mobile network to authenticate a security element, Operating by an operator, the method comprising: causing the A-entity to store a first authentication parameter in a secure element; B - causing the entity to transmit a first authentication parameter to the mobile network operator so that the operator can record it in its authentication system for authenticating the security element; C - Upon occurrence of an event, the remote platform is authorized to replace the first authentication parameter with the second authentication parameter if its authentication to the authentication system fails the next time the security element attempts to connect to the mobile network Sending an indicator to the security element to inform the security element; Causing an entity to transmit a second authentication parameter to an operator upon occurrence of a D-event, thereby allowing an operator to replace the first authentication parameter with a second authentication parameter in its authentication system; E - if the security element subsequently fails to connect to the mobile network and if the indicator is present in the secure element, the security element may authenticate itself to the mobile network using the second authentication parameter, And replacing the first authentication parameter with the second authentication parameter.
