Aimed at overcoming the limitations of current authentications on trusted platform

this dissertation puts forward an improved method based on one-way accumulator

and constructs its solution in detail.New solution introduces ring signature to protect client′s privacy with ring signature′s anonymity

what′s more

the ring length is fixed by the one-way accumulator which accumulates all the members′ information so that the ring won′t be too large with considerable members.During validation

the efficiency is promoted for the diminishment of the hash-compute times

encrypt-compute times and decrypt-compute times.Compared to existing ways of authentication

it indicates that new solution has lower time complexity and space complexity.At the same time

new solution guarantees anonymity and effectiveness

in addition to it makes up traditional ring-signature′s weakness mentioned above;it has high efficiency on the premise of security.
