Embodiment Construction

[0034] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principle of the present invention.

[0035] A specific example of the present invention is figure 1 As shown, the communication system adopting the counter synchronization method with low interaction overhead includes the communication device of the sender, referred to as the sender, the communication service system with limited channel resource conditions, referred to as the communication service system, and the communication device of the receiver, referred to as the receiver. The sending end and the receiving end are only defined in one communication process. When other communication processes occur, the roles of the sending end and the receiving end may be interchanged. For example, the...

Abstract

The invention relates to a low-interaction-overhead counter synchronization method. The method comprises the steps of splitting a time counter value of a sending end; sending a low part of a counter value of the sending end; extracting the low part of the counter value of the sending end by a receiving end; splitting a time counter value of the receiving end; and through comparison of the low parts of the counter values of the sending end and the receiving end, carrying out restoration at the receiving end, thereby obtaining the time counter value of the sending end, and realizing the synchronization of counters of the communication sending end and receiving end. The method is applicable to a communication system with limited channel resources; in a data communication encryption application, according to the method, cipher information of the two communication parties is synchronized with low interaction overhead; and accurate encryption and decryption behaviors of the sending end and the receiving end are realized.

Description

technical field [0001] The invention relates to the technical field of counter synchronization, in particular to a counter synchronization method with low interaction overhead. Background technique [0002] For some communication systems with limited channel resources, such as satellite communication systems serving ground terminal communications, there is an essential difference in the use of channel resources from ground network transmission systems with good channel resources. Such communication systems usually have the following characteristics: [0003] 1. One end of the communication (usually the initiator) cannot use link resources frequently. That is to say, the communication system strictly limits the service frequency of each user. [0004] 2. The content length of a single communication is strictly controlled. The length of information sent is usually measured in bits, not bytes. [0005] 3. While the use of resources is limited, this type of communication sys...
