Abstract:
1. In a mobile communications network having mobile communications capabilities and supporting a secure messaging service that allows a message sender and at least one message receiver exchanging messages encrypted by means of a cryptographic process performed by the message sender, so as to obtain an encrypted message that can be decrypted by a corresponding cryptographic process performed by the intended message receiver, wherein at least one among the message sender and the message receiver is a user of the mobile communications network, a method comprising: modifying, via the mobile communications capabilities of the mobile communications network, a parametric cryptographic algorithm used by said user of the mobile communications network for performing said cryptographic process, wherein the parametric cryptographic algorithm comprises a plurality of combinable cryptographic sub-algorithms; and managing modifications to the parametric cryptographic algorithm via a messaging security manager server connected to the mobile communications network and to the Internet and having an interface allowing the performance of management operations, wherein modifying said parametric cryptographic algorithm comprises:
