Embodiment

[0159] In the system initialization process of this embodiment, the preferred anonymity level K=5, the preferred length parameter N corresponding to the K-level queue (including the input queue) 1 , N 2 ,...,N 5 100, 200, 400, 800, 1600 respectively. The master server will p, q, g, K, N 1 , N 2 ,...,N 5 , public key vector {y 1 ,y 2 ,...,y 5} are stored as public parameters, and any user can query the master server for these parameters. In this embodiment, after the system initialization is completed, the K-level queues of the system are all empty.

[0160] After the system initialization is finished, a certain user generates anonymous messages (a, b, c, d) according to the method provided by the present invention. In this embodiment, it is assumed that the user selects any anonymity level between 1 and 5 with equal probability, that is, the probability of the user outputting his plaintext message from any queue is equal.

[0161] After the system is initialized, it ...

Abstract

The invention relates to an anonymous message exchange system with optional anonymity degree and its realization method. The existing anonymous message exchange system cannot flexibly adapt to changes in user message anonymity requirements. The present invention includes a main control server for generating initialization parameters, responding to query requests, and coordinating the work of subsystems, a user message input queue for buffering messages, K-1 intermediate queues for buffering intermediate results, and a queue for inputting A message processing subsystem for processing messages in the message, an output queue for caching messages waiting to be distributed, and a message distribution subsystem for extracting messages from the output queue and sending them to message receivers according to the address field of the message. Based on the present invention, users can make a trade-off between anonymity and forwarding delay, and flexibly choose their own anonymity and delay parameters. All messages of anonymity levels are mixed together for processing, and messages of different anonymity levels can be exchanged Protect.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to an anonymous message exchange system with an optional anonymity degree and an implementation method thereof. Background technique [0002] The basic function of the message exchange system is to receive input messages from multiple senders, and after processing, forward the messages to different receivers according to the destination address of each message. A network switch is a typical message exchange system. The message exchange system generally includes four main parts: input queue, output queue, message processing subsystem and message distribution subsystem. Messages from different senders are first buffered into the input queue, and the message processing subsystem cyclically obtains messages from the input queue, processes the messages, and puts them into the output queue. The message distribution subsystem forwards the messages in the output q...
