Abstract: A method and system for securing in-vehicle ethernet links are disclosed. According to one embodiment, a method comprises receiving from an authenticator, via an insecure channel, a public key of the authenticator, a random number, and a challenge. A private key of the peer that was supplied to the peer is accessed from local storage at the peer. A state machine computes a session key for the peer, based on the random number, the public key of the authenticator, and the private key of the peer. The state machine computes a peer response to the challenge using the session key for the peer and a symmetric cipher function.

Abstract: A method and system for securing CSI and DSI links using enhanced authentication and cloud tracking are disclosed. According to one embodiment, a method comprises receiving at the receiving device an encrypted information signal from the transmitting device. The encrypted information signal includes a unique identifier of the transmitting device. The method further comprises testing whether a whitelist at the receiving device includes the unique identifier of the transmitting device. The encrypted information signal is decrypted producing a retrieved information signal only if the whitelist includes the unique identifier of the transmitting device; and otherwise terminating communication with the transmitting device.

Abstract: A method and system for bi-directional communications are disclosed. According to one embodiment, a method comprises configuring the first device to enter an active mode according to a non-overlapping (NOL) schedule, the second device being in a silent mode. A transmitter of the first device transmits a first local data signal for a duration not exceeding a maximum tolerable silent duration of the second device. The first device is configured to enter the silent mode after transmitting the first local data signal, according to the NOL schedule.
