Embodiments described herein provide systems and methods to prevent, or provide a countermeasure, to a co-existence attack, for example, that may occur in a Security Credential Management System (SCMS) where both regular butterfly key (RBK) protocol and unified butterfly key (UBK) protocol are supported. Embodiments described herein provide, support, employ, or implement hardware acceleration for a Hardware Security Module (HSM), for example, for cryptographic operations (e.g., block ciphers, digital signature schemes, and key exchange protocols).

Systems and methods for countering co-existence attack

In a vehicle-to-everything (VX) technology environment, systems and methods are provided for extending the distribution of activation codes (ACs) in an Activation Codes for Pseudonym Certificates (ACPC) system, in a privacy-preserving manner, to a unicast mode of communication. In this unicast ACPC (uACPC), in some embodiments, the ACs are distributed by the back-end system via a unicast channel upon the receipt of the vehicle's direct request for its respective ACs. In some embodiments, uACPC can leverage edge computing architecture for low latency delivery of certificate revocation lists (CRLs) and higher availability for the distribution of ACs.

Systems and methods for accelerated certificate provisioning

Video data and audio data of multiplexed data are separated. Abstract video data is generated from the separated video data and abstract audio data is generated from the separated audio data. Then, the abstract video data and the abstract audio data are packed and a packed video and audio data management table is generated from packed video and audio data Dand video and audio data synchronization information D. The packed video and audio data management table comprehensively manages the packed video and audio data. Thus, data of various video formats, various audio formats and various multiplexing formats can be monistically managed.
