Problems solved by technology

However, the processing capability, storage capability and communication capability of the sensor node itself are relatively weak, so that the traditional end-to-end encryption mechanism cannot be used in the wireless sensor network, and the public key encryption in the traditional network is no longer applicable, and digital signature cannot be performed.

Embodiment Construction

[0054] Certain embodiments of the accompanying drawings of the present invention are described in more detail below.

[0055] according to figure 1 , the present invention is built on the basis of model checking technology, and the specific implementation mode is:

[0056] 1. Establish a state transition system based on time automata

[0057] The state transition system based on timed automata described in the present invention uses timed automata modeling to describe the possible states of the protocol during operation for the sender, receiver and intruder involved in the protocol respectively.

[0058] For the sender, a timed automaton is used to describe the state process of executing the protocol. When the sender communicates securely with the receiver, the protocol starts to execute. First, the sender enters the idle state from the dormant state, sets up a status flag, denoted as A, and sets up a clock variable Ta at the same time. A and Ta change continuously with the ...

Abstract

The invention discloses a wireless sensor network security protocol verification method based on model checking. A state migratory system formed by a timed automata represents a wireless sensor network security protocol, a modal / time sequence logical formula represents the conditions which need to be met by the security protocol in the wireless sensor network, and the verification of the wireless sensor network security protocol is converted into a model carrying out verification that whether the state migratory system is a formula. According to the wireless sensor network security protocol verification method based on model checking, the characteristics of the wireless sensor network are sufficiently considered during the security protocol verification process, a clock restraint condition is added in the modal / time sequence logical formula, and comprehensive verification can be conducted on the wireless sensor network security protocol.

Description
