Description
Technical Field
The invention belongs to the technical field of hotel entrance guard, and particularly relates to a safe intelligent hotel entrance guard control system and method based on NFC.
Background
Currently, the current state of the art commonly used in the industry is such that: currently, hotel security issues have become a very important issue for public or individuals, where various security systems have been proposed and developed for some critical processes. An intelligent hotel access control system is a highly intelligent electronic safety precaution system developed in recent years and is mainly used for controlling each room or entrance and exit of a hotel. Along with the appearance of more and more high-tech crimes, the traditional hotel access control system is more and more weak, the security of a hotel is improved from the source, the increasingly improved security requirements of the public are met, and the design of the safe intelligent hotel access control system is an urgent need of people.
In summary, the problems of the prior art are as follows: with the appearance of more and more high-tech crimes, the traditional hotel access control system is increasingly weak. Traditional hotel access control systems are mainly divided into radio frequency card access control systems and biometric access control systems. The radio frequency card access control system has a single identification mode, most radio frequency card accesses only complete a basic door lock control function, a card user is not identified, the radio frequency card access control system rarely sees that the uniqueness of the card user can be confirmed, and the radio frequency card is easily copied by illegal molecules, so that the safety of the access control system is reduced. Biometric access control systems are widely used and popularized with the advancement of automatic identification technology. Compared with a radio frequency card access control system, the biometric access control system can achieve one-to-one correspondence of keys and users, but the biometric access control system has over high requirements on the users and the use environment, and can cause the user to be incapable of carrying out complete biometric identification and authentication after the tissues used as the biometric characteristics of the user are damaged or lost.
The difficulty and significance for solving the technical problems are as follows: to solve the above problems, the present invention needs to satisfy: 1. no additional cards or "keys" need to be carried by the user. 2. Not entirely on the biometric regime. 3. Has good safety and can resist most known attack means. The cryptology-based security system and the near field communication technology are good medicines for solving the problems. The system which uses a symmetric encryption system, an asymmetric encryption system, a message signature and a message verification code algorithm in cryptography is acknowledged to have extremely high security, and the system which uses a session key one-time pad in the patent increases the difficulty of encrypted message decryption. Due to the limitation of the transmission distance of the near field communication technology, the near field communication technology ensures that the message sent to the door lock by the mobile phone of the user is not easy to steal, and the safety of the near field communication technology in the current social environment is improved. The invention can realize good authentication and identification effects on any legal user in any environment, can promote the safety of the hotel access control system, and can properly expand the invention at the present of fast internet development to realize a non-foreground hotel.
