  • In the paper, an improved secret sharing scheme based on elliptic curve cryptography is proposed. It guarantees the mutual identity authentication between the legal dealer and the participating parties and can protect against the cheating action. The problems of renew and reuse are properly treated. The scheme may be applicable in practical network communication.
