摘要： The invention is a method for updating a first secret data (76) in a credential container (20) including a subscriber identity module. The credential container comprises a set (77) of secret parameters customized for a network operator and is configured to execute a symmetric mutual authentication algorithm using said set. The credential container receives from a remote server (30) a second secret data (78) enciphered using a second algorithm different from said symmetric mutual authentication algorithm and a subset (79) of said secret parameters, the credential container deciphers the enciphered second secret data by using both the subset and a third algorithm and replaces the first secret data with the second secret data.
