    摘要: In one example an apparatus comprises a computer readable memory, a signing facility comprising a plurality of hardware security modules, and a state synchronization manager comprising processing circuitry to select, from the plurality of hardware security modules, a set of hardware security modules to be assigned to a digital signature process, the set of hardware security modules comprising at least a first hardware security module and a second hardware module, and assign a set of unique state synchronization counter sequences to the respective set of hardware security modules, the set of state synchronization counter sequences comprising at least a first state synchronization counter sequence and a second state synchronization counter sequence. Other examples may be described.

    摘要: Systems, apparatuses and methods may provide for infrastructure node technology that conducts a mutual authentication with a vehicle and verifies, if the mutual authentication is successful, location information received from the vehicle. The infrastructure node technology may also send a token to the vehicle if the location information is verified, wherein the token includes an attestation that the vehicle was present in a location associated with the location information at a specified moment in time. Additionally, vehicle technology may conduct a mutual authentication with an infrastructure node and send, if the mutual authentication is successful, location information to the infrastructure node. The vehicle technology may also receive a token from the infrastructure node.

    摘要: Embodiments are directed to post quantum public key signature operation for reconfigurable circuit devices. An embodiment of an apparatus includes one or more processors; and a reconfigurable circuit device, the reconfigurable circuit device including a dedicated cryptographic hash hardware engine, and a reconfigurable fabric including logic elements (LEs), wherein the one or more processors are to configure the reconfigurable circuit device for public key signature operation, including mapping a state machine for public key generation and verification to the reconfigurable fabric, including mapping one or more cryptographic hash engines to the reconfigurable fabric, and combining the dedicated cryptographic hash hardware engine with the one or more mapped cryptographic hash engines for cryptographic signature generation and verification.
