Method for selecting P2P sensor network security service under social network environment

Abstract

The invention provides a method for selecting a P2P sensor network security service under a social network environment. The method comprises the steps: step 1, building a service opportunity list according to an unexpected event sent by an operator; step 2, identifying a built relative service opportunity from the service opportunity list; step 3, calculating relative security indexes for each service opportunity; step 4, under social P2P of a sensor network, selecting and outputting a proper security service for each user according to the security indexes. The method for selecting the P2P sensor network security service under the social network environment is low in service retransmission probability, thereby reducing loads of a server side; better user applicability and controllability and stronger service discovery and selection capability are achieved.

Description

technical field [0001] The invention relates to the field of sensor network security services, in particular to a P2P sensor network security service selection method in a social network environment. Background technique [0002] In today's world of information globalization, sensor networks have gradually emerged in the Internet of Things and have been widely used in various fields such as industry, agriculture, medical care, and transportation, and have played a pivotal role in the intelligence and informatization of these industries. With the continuous development of the Internet of Things technology, the characteristics and principles of the social network are given to the sensor network, so that objects can generate social attributes, so that objects can actively interact with information and services facing the social network, and become an important node of the social network, thus breaking through It has become a brand new network model. In existing IoT sensing sys...

However, these works do not consider the service selection problem in the face of the complexity, randomness, and time independence characteristics of sensor network-based social P2P, and the security cannot be well reflected.
