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(shū)

It should be understood that although terms such as “first”, “second”, and “third” can be used in the one or more implementations of the present specification to describe various types of information, the information is not limited to these terms. These terms are only used to distinguish between information of the same type. For example, without departing from the scope of the one or more implementations of the present specification, first information can also be referred to as second information, and similarly, the second information can be referred to as the first information. Depending on the context, for example, the word “if” used here can be explained as “while”, “when”, or “in response to determining”.

The previous descriptions are only example implementations of the one or more implementations of the present specification, and are not intended to limit the one or more implementations of the present specification. Any modification, equivalent replacement, improvement, etc. made without departing from the spirit and principle of the one or more implementations of the present specification shall fall within the protection scope of the one or more implementations of the present specification.
