Abstract :
On the elliptic curve cryptosystem proposed a new multi-proxy signature scheme - (t, k, n) threshold proxy signature scheme. In new program proxy signature and (t,k,n) threshold secret sharing scheme will be combined, and will not over-concentration of the rights of the proxy signer. Computation of the program is small, security is high, the achieve efficiency and the utility is better. Can prevent a malicious user´s forgery attack and have the security properties of proxy signature.
