摘要

A computer-implemented method, non-transitory, computer-readable medium, and computer-implemented system are provided for implementing privacy protection. In an implementation, a public key pk={N, h} corresponding to a target user is obtained, where h is a generator of a predetermined cyclic group with a size of k in a random number space Z*N, a length of k is i bits, a length of N is n bits, and i<

說(shuō)明書

Specific implementations of the present specification are described above. Other implementations fall within the scope of the appended claims. In some situations, the actions or steps described in the claims can be performed in an order different from the order in the implementations and the desired results can still be achieved. In addition, the process depicted in the accompanying drawings does not necessarily require a particular execution order to achieve the desired results. In some implementations, multi-tasking and parallel processing can be advantageous.

The term used in the one or more implementations of the present specification is merely intended to describe a particular implementation and is not intended to limit the one or more implementations of the present specification. The terms “a” and “the” of singular forms used in the one or more implementations of the present specification and the appended claims are also intended to include plural forms, unless otherwise specified in the context clearly. It should be further understood that the term “and/or” used in the present specification indicates and includes any or all possible combinations of one or more associated listed items.
