METHOD OF REPLACING AT LEAST ONE AUTHENTICATION PARAMETER FOR AUTHENTICATING A SECURITY ELEMENT AND CORRESPONDING SECURITY ELEMENT
First Claim
1. A method of replacing at least one authentication parameter for authenticating a security element co-operating with a terminal, said authentication parameter enabling an authentication system of a mobile network to authenticate said security element, said mobile network being operated by a mobile network operator, said method comprising:
- A—
Having an entity store in said security element a first authentication parameter;
B—
Having said entity transmit to said mobile network operator said first authentication parameter so that said operator can record it in its authentication system for authenticating said security element;
C—
On occurrence of an event, having a remote platform transmit to said security element an indicator informing said security element that it is authorized to replace said first authentication parameter with a second authentication parameter if its authentication fails with said authentication system the next time it attempts to connect to said mobile network;
D—
On occurrence of said event, having said entity transmit to said operator a second authentication parameter so as to enable said operator to replace said first authentication parameter by said second authentication parameter in its authentication system;
E—
In the event of subsequent failure of said security element to connect to said mobile network and if said indicator is present at said security element, replacing said first authentication parameter with said second authentication parameter at said security element so that said security element can authenticate itself with said mobile network by means of said second authentication parameter.

Abstract
A method of replacing an authentication parameter for authenticating a security element co-operating with a terminal includes storing in the security element a first authentication parameter; transmitting to a mobile network operator the first authentication parameter for the operator to record it in its authentication system; on occurrence of an event, having a remote platform transmit to the security element an indicator informing the security element that it is authorized to replace the first authentication parameter with a second authentication parameter if its authentication fails; on occurrence of the event, having the entity transmit to the operator a second authentication parameter to replace the first authentication parameter; and in the event of subsequent failure of the security element to connect to the mobile network and if the indicator is present at the security element, replacing the first authentication parameter with the second authentication parameter at the security element.

10. Security element comprising a first authentication parameter to a mobile network, said first authentication parameter enabling an authentication system of said mobile network to authenticate said security element, comprising:
-
Means for storing an indicator informing said security element that it is authorized to replace said first authentication parameter by a second authentication parameter if its authentication fails with said authentication system the next time it attempts to connect to said mobile network; Means for replacing said first authentication parameter by said second authentication parameter if said security element fails to connect to said mobile network with said first authentication parameter, said means for replacing being activated if said indicator is present at said security element, so that said security element can authenticate itself with said mobile network by means of said second authentication parameter. - View Dependent Claims (11, 12, 13)
