  • Cryptographic key generation using kummer varieties
    Patent number: 11792002
    Abstract: An authenticated, ID-based private/public key pair, with a self-certified public key, is generated using Kummer arithmetic without bilinear pairings. Two or more parties can generate such key pairs and use them as their respective long-term key pairs which, when combined with the parties' short-term key pairs, can allow the parties to establish an authenticated, short-term shared key. Some embodiments are suitable for connected vehicles communicating with each other and/or with other systems. Other features are also provided.
    Type: Grant
    Filed: December 26, 2019
    Date of Patent: October 17, 2023
    Assignee: LG ELECTRONICS INC.
    Inventors: Harsh Kupwade Patil, Paulo Sergio Licciardi Messeder Barreto, Jefferson E. Ricardini Fernandes De Oliveira

  • Systems and methods for a butterfly key exchange program
    Patent number: 11165592
    Abstract: Embodiments described herein provide an implicit protocol with improved resource and bandwidth efficiency. A post-quantum secure approach for issuing multiple pseudonym certificates from a small piece of information is provided, while traditionally most encryption schemes are vulnerable to post-quantum attacks (e.g., in a traditional SCMS). Long-term security can be improved with the post-quantum protocol.
