Recognition Of Things In RF Technology

With the continuous development and improvement of wireless sensor technology, the Internet of things in our lives more and more widely used, from the basic necessities of life to transport and other public services, are inseparable from the network services, can be said that the Internet of things "care" moment of daily production and our life. Technology innovation technology of the Internet of things is not single, but a number of innovative technology in the application and integration of the IOT.Internet of things refers to the concept of an object to the object, it requires that the object and interconnected, objects of any change can be perceived by the perception network information, and make information according to the actual demand of intelligent computing and decision making. Sensor networks consists of small sensing nodes, the distribution in with every corner of our daily production and living environment, if there is no a perfect security system, cannot bring the benefits to our life. IOT security issues involved in the iot architecture of all levels, and complicated, because there is no uniform safety standards, it difficult to establish a unified security system effectively.Universal composable model is a kind of tighter security model, communication protocol of every session is decomposed into sub session, each session are ideal security for agreement. Universal composable model design of security protocols with combination, through the proof of the safety of each substructure, proves that the protocol has good security.LCAP protocol is the rfid security level is higher in the agreement, but due to communication before and after data need to update, so appear all sorts of data are not synchronized.This paper introduces in detail the security protocol of the communication process and the advantages and disadvantages, innovation point is put forward based on improved LCAP agreement. After the improved protocol, database back-end storage before and after the update data, solve the problem that the data are not synchronized. The protocol USES public key and bidirectional authentication technology, has a good forward security. By decomposing protocol session, conform to the requirements of the universal composable model design, achieved ideally security goals.
