Information leakage preventing method and system based on internet of things

Abstract

The invention discloses an information leakage preventing method and system based on the internet of things. An RFID (Radio Frequency Identification Device) chip responder and a reader of an application layer of the internet of things, which are mutually communicated and arranged in the internet of things; and the RFID chip responder stores an electronic carrier of identifying information of things in the internet of things. The method comprises the following steps that the RFID chip responder encrypts a private key and a public key and then transmits encrypted information to the reader of the application layer of the internet of things by a network layer of internet of things; the reader of the application layer of the internet of things decrypts the public key and the private key and generates a new private key every time; and the reader of the application layer of the internet of things encrypts and forwards the new generated private key to the RFID chip responder and readers of other application layers of the internet of things by using the public key. The invention protects the safety of data in the internet of things and prevents the leakage of information by a public key and private key encrypting mechanism. In the whole process of realization, the dynamic replacement of the private key not only further protects information safety but also improves the difficulty of password cracking.

Description

technical field [0001] The invention belongs to the technical field of computer security, and relates to an information leakage prevention method, in particular to an information leakage prevention method based on the Internet of Things; meanwhile, the present invention also relates to an information leakage prevention method based on the Internet of Things. Background technique [0002] The Internet of Things is based on the computer Internet, using RFID, wireless data communication and other technologies to construct an "Internet of Things" covering everything in the world. In this network, items can "communicate" with each other without human intervention. The essence is to use radio frequency automatic identification (RFID) technology to realize the automatic identification of items and the interconnection and sharing of information through the computer Internet. However, with the rapid development of the Internet of Things, the hidden security crisis behind the Internet...

Problems solved by technology

Since the communication is carried out in an open wireless environment, it is possible for the surrounding covert attack to obtain the data information on the transponder just like the reader, which constitutes a threat to security and privacy.
