Embodiment 1.
3G is the 3G (Third Generation) Moblie technology, refers to support the honeycomb mobile communication technology of high speed data transfer.3G service can transmit sound and data message simultaneously, with the key distinction of 2G be lifting on the speed of transmission voice and data, speed is generally more than hundreds of kbps.3G exists four kinds of standard: CDMA2000, WCDMA, TD-SCDMA, WiMAX at present.
VPDN English is Virtual Private Dial-up Networks, is called again Virtual Private Dialup Network, is a kind of of vpn service, is based on dial user's Virtual Private Dialup Network business, namely surfs the Net in the dial-up access mode.The specific implementation of VPDN is to adopt tunneling technique, the data encapsulation that is about to enterprise network is transmitted in the tunnel, the user can realize that by VPDN general headquarters are to the telemanagement of branch offices, remote monitoring, many-sided data transmission demand such as service application, saved user's communications cost, improved the business administration operational paradigm, the while also provides good guarantee for the expansion of client's business.Affiliated enterprise uses the special-purpose account number of VPDN to dial in enterprise headquarters, realizes that local data to the uploading of data center of enterprise headquarters, realize information sharing, the processing of mutual and related service application.
Along with constantly popularizing of 3G network business, operator has released the VPDN business of 3G to the demand of " 3G moves private " for the enterprise customer, that is: based on the Virtual Private Dialup Network business of 3G wireless access way, it is to utilize the L2TP Tunnel host-host protocol, just can build on existing Dial-up Network one virtual, be not subjected to the designated lane of external interference, thereby the mode that realizes the wired dedicated network of similar employing is accessed the intranet resource.
By above analysis as can be known, we can adopt the electricity-selling system design of flowing of technology based on 3G VPDN private network.Adopt this technology at first to reduce the expense of manpower and equipment, owing to can adopting ISP that the ready-made network platform is provided, greatly reduced the input on manpower and equipment; Next has improved business processing speed, 3G network is compared similar GPRS technology higher business processing and transmission performance, 3G VPDN system can also promote the improvement of management information service, power supply administration can utilize this system to improve the flow process of paying the fees, from user friendly angle, improve service brand and the grade of service; 3G network has the characteristics of access whenever and wherever possible, only needs a notebook computer+3G wireless network card, and the sale of electricity of just flowing improves power marketing personnel work efficiency.
1, system group network explanation:
This system has adopted the B/S structure, the electricity-selling terminal equipment that flows has adopted " wireless network card+notebook+printer ", by browser access telecommunications 3G Radio Access Network, adopt the special-purpose account number of VPDN to dial in special-purpose certificate server at secure context simultaneously and come access authentication, safety certification by after could access the VPDN server and obtain the professional address of Qinghai sales service system, obtain the authority (if account number not by authenticating do not possess the function of networking) of access enterprise networks network.
We have also installed router and fire wall in the electric power side, made security strategy on fire wall, only allow the wireless sale of electricity front end processor in the port access DMZ district of appointment, the database that wireless sale of electricity front end processor is received after instruction with the sales service system carries out data interaction, with data feedback to the electricity-selling terminal that flows.
2. security of system solution
System is connected with intranet by radio channel due to the Qinghai electric power wireless payment, therefore at first design will guarantee access security, do not allow intranet is produced safely any impact, so the resolution system safety problem is the 3G wireless network key that electricity-selling system uses that flows.
This time we study test at the 3G VPDN private network of having rented China Telecom, secure context be mainly by proprietary APN+ binding access authentication, L2TP privately owned tunnel, when IPSEC safety encipher technology realizes that 3G disposes to access authentication, the security doctrine encrypted of private ownership, End-to-End Security end to end, concrete deployment scheme is as follows:
● proprietary APN+ binding access authentication
When the 3G wireless access of the terminal site of flowing is disposed, the private network APN(Access Point Name that is first distributed by operator).The access of 3G router is adopted in the terminal site, operator can (IMSI be the number of a mobile subscriber of unique identification in carrier network with site user's IMSI information, formed by 15 bit digital, be stored in SIM card), terminal user's account and password configured in advance be on operator's certificate server.When the 3G of site router is initiated wireless connections, only allow the legal user of binding information by the aaa authentication of user name, password after access 3G dedicated network, prevent illegal SIM card user dial-in customer 3G private network.
In addition, can the PIN code defencive function of SIM card be set by the 3G router further, only know that the PIN password of SIM card could trigger the 3G dialing, prevent that the disabled user from getting the illegal operation of carrying out after user's SIM card, guaranteed the use safety of SIM card.
● L2TP+IPSEC VPN privately owned tunnel
For the data service that guarantees 3G access site transmit in operator's IP kernel heart net private ownership, we are to the VPDN business of the application user 3G of group of enterprises of operator, build virtual a, designated lane that be not subjected to external interference on existing Dial-up Network, thus secure access intranet resource.
Operator can provide LAC end router and supporting AAA (Authentication checking, Authorization authorize, the Accounting keeps accounts) server of L2TP.We adopt a router as the LNS end of L2TP at enterprise's one-level net or secondary net convergence-level, and dispose an aaa server.The LAC router mainly is responsible for the access authentication to 3G subscription, sets up L2TP Tunnel with the proprietary LNS of this user owned enterprise.Needed username and password when the aaa server that enterprise's one-level net or secondary net converge is mainly deposited the site router and connected.The form of user name is XX@XX.COM, and wherein the character string of@front can be by the user side self-defining, and the character string of@back is domain name.Operator's aaa server is confirmed this user's access authority by domain name.Operator's aaa server must be consistent with the username and password of enterprise's aaa server.
To safety encipher principle end to end, as mentioned before, 3G technology has the encrypted authentication technology of self, but the encrypted authentication technology of 3G is only for wireless portion, and in IP kernel heart mesh portions, the L2TP Tunnel between from LAC to LNS is not encrypted, data or expressly transmit.And also can be through the IP network of operator in the middle of from LAC to the network, in order to reach encrypted transmission end to end, need to adopt IPSEC to realize encryption end to end between electrical network point on sale and electric power general headquarters router.
