SYSTEM AND METHOD FOR SECURELY SHARING CRYPTOGRAPHIC MATERIAL

This abstract first appeared for US patent application 20250097020 titled 'SYSTEM AND METHOD FOR SECURELY SHARING CRYPTOGRAPHIC MATERIAL

Original Abstract Submitted

systems and methods described herein relate to techniques in which multiple parties each generate and exchange quantities that are based on a shared secret (e.g., powers of the shared secret) without exposing the shared secret. according to a protocol, two or more parties may exchange sets of elliptic curve points generated over polynomials that can be used, by each of the two or more parties, to determine a power of a shared secret. the protocol may be utilised as part of determining parameters for a smart contract that is broadcast to a blockchain network (e.g., bitcoin). based on the protocol, an additional party (e.g., a third party different from the two or more parties) may perform a computational task such as execution of the smart contract.
