<p>A mobile communications network (100) has mobile communications capabilities and supports a secure messaging service (140, 145), such as an SMS messaging service, that allows a message sender (120s) and at least one message receiver (120r) (at least one among the message sender and the message receiver being a user of the mobile communications network) 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; end-to-end security of the exchanged messages is thus achieved. A cryptographic algorithm, exploited by the user of the mobile communications network for performing the cryptographic process, is modified by exploiting the mobile communications capabilities of the mobile communications network. Robustness and reliability over time of the end-to-end security messaging is improved.</p> |
