Threshold Shared Verification Signature Encryption Scheme Based on Elliptic Curve

This paper proposes a threshold shared verification signature encryption scheme which based on elliptic curve, in which any t among n verifiers can verify the validness of signature, otherwise it cannot. The scheme integrates digital signature scheme with public key cryptography system. Compared with proposed threshold shared verification signature encryption scheme, it has higher secrecy of data transmission, requires shorter secret key distance and smaller communication cost, performs efficiently and be able to prevent verifier cheat, etc.
