Abstract :
The improved authenticated (t, n) threshold signature encryption scheme based on ECC can not only shorten the time for data transmission, make operation accelerate and substantially reduce the load on the signer, but also have higher security not to be deceived by the third. The scheme uses a division-of-labor signature that decreases the workload on the signer and improves the performance; an idea in which the private key is concealed confines the authority of the SA, consequently, the new scheme is safer. Moreover, the scheme is based on the elliptic curve cryptosystem, supporting the practical use of the scheme, because of its highly efficient performance and comprehensiveness of security
