Latest Patent Applications
One of Sylvain Morandi's notable patent applications is titled "Ensuring Secure Attachment in Size Constrained Authentication Protocols." This application describes a method for securely attaching a mobile device to a server using a protocol that has data size encoding constraints. The method prevents the use of traditional ciphering and includes an initialization phase that utilizes a range of ephemeral International Mobile Subscriber Identities (IMSIs) stored in credential containers of mobile devices. The process involves an associated group master key shared by the server and credential containers, which helps initiate a session using a server random value. The initialization phase employs a limited payload in a mobile device-to-server message to send a randomly chosen rIMSI, enabling the server to generate keys for a secured communication phase.
Conclusion
Sylvain Morandi's contributions to secure authentication protocols highlight his innovative approach to mobile device security. His work at Thales Dis France Sas demonstrates his commitment to advancing technology in this critical area.
