Abstract: Embodiments described herein enable the generation of cryptographic material for ranging operations in a manner that reduces and obfuscates potential correlations between leaked and secret information. One embodiment provides for an apparatus including a ranging module having one or more ranging sensors. The ranging module is coupled to a secure processing system through a hardware interface to receive at least one encrypted ranging session key, the ranging module to decrypt the at least one encrypted ranging session key to generate a ranging session key, generate a sparse ranging input, derive a message session key based on the ranging session key, and derive a derived ranging key via a key derivation cascade applied to the message session key and the sparse ranging input, the derived ranging key to encrypt data transmitted during a ranging session.

Abstract: Techniques are disclosed relating to electronic security, e.g., for authenticating a mobile electronic device to allow access to system functionality (e.g., physical access to the system, starting an engine/motor, etc.). In some embodiments, a system and mobile device exchange public keys of public key pairs during a pairing process. In some embodiments, an asymmetric transaction process includes generating a shared secret using a key derivation function over a key established using a secure key exchange (e.g., elliptic curve Diffie-Hellman), and verifying a signature of the system before transmitting any information identifying the mobile device. In various embodiments, disclosed techniques may increase transaction security and privacy of identifying information.
