Latest Patents
One of Hemant Purswani's latest patents involves methods, devices, and servers for the as-needed update of a trusted list. In this innovation, an eSIM server receives a request for an eSIM of a particular type from a wireless device. The server evaluates the request and communicates with a second eSIM server, which is not initially trusted by the secure element (SE) of the wireless device. The eSIM server sends a policy update to the wireless device, which is then passed to the universal integrated circuit card (UICC). The UICC updates the trusted list with the identity of the second eSIM server. When the wireless device downloads a bound profile package (BPP) containing an eSIM from the second eSIM server, the UICC validates the BPP based on the updated trusted list, allowing the eSIM to be installed on the UICC.
