  • LIGHTWEIGHT DISTRIBUTED SIGNATURE PROTOCOL FOR MOBILE COMPUTING AND IOT DEVICES
    Publication number: 20230006811
    Abstract: The techniques described herein may provide an efficient and secure two-party distributed signing protocol, for example, for the IEEE P1363 standard. For example, in an embodiment, method may comprise generating, at a key generation center, a first partial private cryptographic key for a user ID and a second partial private cryptographic key for the user ID, transmitting the first partial private cryptographic key to a first other device, transmitting the second partial private cryptographic key to a second other device, and generating a distributed cryptographic signature for a message using the first partial private cryptographic key and the second partial private cryptographic key.
    Type: Application

  • Efficient and secure distributed signing protocol for mobile devices in wireless networks
    Patent number: 11516658
    Abstract: The techniques described herein may provide an efficient and secure two-party distributed signing protocol for the identity-based signature scheme described in the IEEE P1363 standard. For example, in an embodiment, a method may comprise generating a distributed cryptographic key at a key generation center and a first other device and a second other device and generating a distributed cryptographic signature at the first other device using the second other device.
