Abstract
Method and system for updating an encryption key used for the encryption of a password in a telephone exchange system comprising a telephone exchange (LE), a maintenance center (SC), a first database (DB ) containing user-specific information, and a second database (DB ) containing the encryption methods used and the associated encryption keys. The user information contains data indicating the encryption key used last and the password encrypted using this encryption key. When the user is logging on in the system, the encryption key last used data is compared with the current encryption key data. If these differ, the user is identified by the password encrypted with the encryption key used last, and the encryption key last used data is updated with the current encryption key of the telephone exchange system, and the encrypted password is updated to make it consistent with the current encryption key.
