Embodiment Construction
[0020] Enhancing the security of tower crane information is one of the main objectives of this system, and it is also the basic requirement of the project entrusting party. 3G is selected as the wireless transmission method of this system, and its strong confidentiality is one of the main considerations. In the 3G network, the link between MS and SGSN can be encrypted, which can reduce the probability of wireless information being intercepted in the air, and greatly improve its information privacy and security. The process of authentication and encryption of data transmitted by the tower crane will be described in conjunction with the accompanying drawings:
[0021] 1) The authentication process is as follows (such as figure 1 shown):
[0022] a. When the tower crane information is transmitted through the 3G network, first the SGSN sends the authentication information to the HLR, and the HLR responds to the corresponding authentication information and sends the authentication...

The invention discloses a method for authenticating and encrypting tower crane information based on 3G (The 3rd Generation Telecommunication) transmission. The method is characterized by comprising the following steps of: 1) carrying out authentication process: firstly, sending authentication information to an HLR (Home Location Register) by an SGSN (Service GPRS Supporting Node) and corresponding responding the authentication information by the HLR; sending an authentication triple into the SGSN; sending an authentication request to an MS (Mobile station) and calculating by the MS; and then judging whether an SRES' (Signed Response) which is sent by the SGSN is the same as an SRES which is sent by the HLR; 2) carrying out encryption process: firstly, generating a secret key by parameters and data through a ruled algorithm; permanently storing the secrete key on the HLR and the MS; and finally, carrying out data encryption on the obtained secrete key through a GEA (Global Elimination Algorithm) and then transmitting the encrypted secrete key into tower crane information through a 3G network. According to the method provided by the invention, the privacy and the safety of user communication are effectively protected and the requirements of the user on the authenticity and the privacy of the data are met; and the cost of the method is low so that the method is applicable to being widely popularized in a tower crane system.
Description
technical field [0001] The invention relates to a wireless communication method, in particular to a method for improving the information security of tower cranes based on 3G transmission by utilizing authentication and encryption methods between MS and SGSN. Background technique [0002] At present, the characteristic of the wireless communication system is that user data must be exposed to the air interface of the wireless access network during the transmission process. Therefore, the security of transmitting user data on the air interface is threatened to a certain extent. In order to ensure the security of information and protect the rights and interests of users and operators, the usual solution is to encrypt and transmit user data on the air interface of the wireless access network, so as to prevent user data from being monitored and cracked. In addition, the flexible networking capabilities and communication service capabilities of many communication methods are very w...
