Key management is the core problem of network system security.In which,the critical problem is key sharing and recovering.Based on the discrete logarithm problem and conic curve cryptography,an efficient multilevel-secret sharing scheme is designed.The proposed scheme has the following properties:cheating of the dealer or any participant can be detected efficiently,providing identity authentication of participants,and the shadows of key validation.
