Latest Patents
Hanhisalo's latest patents include innovative solutions for enhancing security and privacy in sidelink communications. One of his patents focuses on providing security mechanisms to protect Layer 2 (L2) identifiers used in groupcast communications over the sidelink, such as the PC5 interface. This invention aims to prevent the need for a User Equipment (UE) to periodically refresh L2 identifiers, which can lead to increased signaling overhead and latency. To mitigate tracking risks, a group identifier is utilized as a source L2 ID in groupcast messages, and a message authentication code (MAC) is introduced to authenticate the UE during group discovery requests.
Another significant patent involves a method for dynamically providing trust information to communication devices within a network. This method allows network equipment to determine and communicate the trustworthiness of various access networks to registered communication devices. The process includes verifying the protection of trust information messages and storing the protected trust information list for future reference.
