Research On Internet Of Thins(IOT) Distributed Data Storage And Encryption And Access Control

Internet of Things is a link through the RFID devices, infrared sensors, global positioning systems, laser scanners, and sensor nodes sensing equipment, as agreed in the agreement and anything connected to the Internet, carry out information exchange and communication, to achieve the intelligent identification, location, tracking, monitoring and management functions of a network. Internet of Things are linked with the Internet, its core and foundation is still the Internet, Extension and expansion of the network is based on the Internet, And its clients extends between any kind articles. With the rapid development of information technology, Information security connotations also continue to extend, giving security these information under a precise definition is difficult. With the development background of the internet and Internet of things, information security can be understood as:under the given secretary-level security conditions, Information system capability to withstand accidents or malicious acts, these events and actions will jeopardize the storage, data processing or transmission and the availability, confidentiality, integrity, non-repudiation and controllability services provided by these systems.This paper firstly outlines the security requirements of internet of things and the current research status; second, this paper presents a special task for internet of things, their security requirements. Data encryption and access control issue were discussed in detail. Moreover, this paper introduces a novel method to solve such problems by using Attribute-Based encryption method. The Attribute-based security system is a combination of an attribute-based access control and authentication mechanism. Its biggest advantage is that, it is not necessary to decrypt the data for access control, thus saving the energy consumption of expensive sensor node for data decryption; a detailed analysis has been given to run this system. This energy utilization, the storage space of wireless sensor nodes, life of the entire internet of things networks and impact on their operation has been tested by simulation.
