Abstract: Embodiments are directed to countermeasures for side-channel attacks on protected sign and key exchange operations. An embodiment of storage mediums includes instructions for commencing a process including an elliptic curve scalar multiplication (ESM) operation including application of a secret scalar value; splitting the secret scalar value into two random scalar values; counting a number of leading ‘0’ bits in the scalar value and skipping the number of leading ‘0’ bits in processing; performing an ESM iteration for each bit of the secret scalar value beginning with a most significant ‘1’ bit of the scalar value including a Point Addition operation and a Point Double operation for each bit on randomized points; performing ESM operation dummy iterations equal to the number of leading ‘0’ bits; and returning an output result for the ESM operation.

Abstract: Systems, apparatuses, and methods to response to detected attacks in an autonomous system based on context of the autonomous system are described. In particular, the disclosure provides an intrusion detection system receiving contexts and contracts dictating particular response guide rails from a higher level components or stack on the autonomous system. The intrusion detection system is arranged to respond to attacks according to the contract without intervention by the higher level components or stack.

Abstract: Systems, apparatuses, and methods to response to distinguish a ghost target from an actual target based on radar signals is provided. In particular, the disclosure provides an intrusion detection system adapted to receive radar signals and distinguish a potential ghost target from a legitimate target based on a signal to noise ratio of the radar signals and a range to the ghost target and the legitimate target.

Abstract: Systems, apparatuses, and methods to response to distinguish a ghost target from an actual target based on radar signals and ranges determined from the radar signals. In particular, the disclosure provides an intrusion detection system receiving ranges and velocities for targets detected based on radar signals, determining a potential ghost target from the received velocities and confirming the potential ghost target based on estimated ranges and perturbations of the vehicle speed.

Abstract: Systems, apparatuses, and methods to establish a mapping between message identifications for messages transmitted on a communication bus and electronic control units transmitting the messages is provided. In particular, retransmission of a low priority message onto the bus is forced such that the retransmitted low priority message overlaps with a higher priority message to determine whether the messages originated from the same ECU.

Abstract: A method comprises maintaining, for at least one remote device, a security footprint and a verified version of a software stack for the remote device, generating an attestation initiation token that includes a nonce to be used to generate an XMSS signature for attestation of the remote device, sending the attestation initiation token to the remote device, receiving, from the remote device, a modified message representative including a hash of a current version of a software stack for the remote device and an indicator of a version number of the current version of the software stack for the remote device, validating the hash, and in response to a determination that the hash is valid, generating an XMSS signature using the security footprint and the current version of a software stack for the remote device and a security footprint for the apparatus.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed for anomaly detection and recovery. An apparatus to isolate a first controller in an autonomous vehicle includes a first controller to control a reference signal of the autonomous vehicle via a communication bus, a second controller to control the reference signal of the autonomous vehicle when the first controller is compromised, and a message neutralizer to neutralize messages transmitted by the first controller when the first controller is compromised, the neutralized messages to cause the first controller to become isolated from the communication bus.
