Latest Patents
One of Guillaume Phan's latest patents is titled "Method for securely diversifying a generic application stored in a secure processor of a terminal." This patent outlines a method that involves generating a server challenge at a distant server, which is then sent to an application. The application generates a first message based on the server challenge, an application challenge, and a unique identifier. This first message is sent to a Root-Of-Trust service in the secure processor, which generates an attestation to ensure the message's integrity and origin. The attestation is then transmitted back to the distant server as part of an enablement request message.
Another significant patent is "Java card application memory footprint optimization." This invention describes a method that separates the code related to personalization from the main application code. By doing so, it allows for the personalization of an application installed from a main package while using a separate package dedicated to personalization. Once the personalization steps are completed, the CPS package can be removed, optimizing memory usage.
