Privacy protection method of sensing information virtual service in Internet of Things

Abstract

The invention discloses a privacy protection method of sensing information virtual service in Internet of Things. Sensor sensing data, a cloud server, a local domain manager, and a user are provided.By aiming at generating of sensing information in a wireless sensing network and during a virtual service process in cloud computation, the data privacy protection strategy of the cloud computation virtual service is divided into two parts: (1) the sensing information is transmitted in the network, and is stored in the cloud server; (2) the sensing data stored in the cloud server is used to provide service for a user. By aiming at each of the safety problems faced by the abovementioned two parts, a safety protection algorithm is provided, and therefore the safety storage algorithm of the sensing information and the safety access algorithm of the data stored in the cloud server are provided.

Description

technical field [0001] The invention belongs to the security field of sensory information data virtual service in the Internet of Things, and its purpose is to provide a security protection mechanism for the data privacy of the sensory information virtual service in the Internet of Things, which involves sensory information in a wireless sensor network Secure transmission of sensing information in cloud servers, secure storage, transmission and virtual services. Background technique [0002] In the Internet of Things, various sensory information is first perceived through corresponding sensory devices. Then, connect to the Internet through the corresponding network. Finally, access to the background server through the Internet. It integrates sensor technology, Internet technology, micro-electro-mechanical technology, embedded system technology and wireless communication technology, etc., and can collaboratively sense, collect, and process information about various environm...

AI Technical Summary

Problems solved by technology

The dynamic changes of sensor nodes will bring security risks to the security of sensor information virtual services

(2) In the Internet of Things, there are many various hardware interfaces and software interfaces, and non-safe hardware interfaces and software interfaces will bring great security risks to the transmission of sensing information

In this case, the security threats faced by its sensing information virtual service will continue to increase; (3) In the Internet of Things, due to the limitation of processing power, wireless sensors generally do not encrypt the transmission of sensing information (even if some The sensor encrypts the transmission of sensing information, but the encryption process is relatively simple, generally belonging to the lightweight one), and non-secure network protocols and transmission methods are more likely to be stolen by illegal users; (4) Sensing information in The transmission process in the Internet of Things is relatively complicated, and generally passes through sensing nodes, base stations, wireless sensor networks, internet wired networks (or wireless networks), cloud servers, etc. The complicated network transmission and interconnection devices are more vulnerable to attacks by illegal users and steal

(5) Cloud computing only provides users with virtualized information services, and users cannot prove the source of sensing information. Invalid user authentication and authorization are more likely to be deceived and disguised by illegal users.

In this case, the various security threats faced by its sensing information will be more serious
