Embodiment 1.
3G i.e. G mobile communication, refers to the cellular mobile telecommunications technology of high speed data transfer.3G service can transmit sound and data message simultaneously, is the lifting in the speed of transmission voice and data with the main distinction of 2G, and speed is typically at hundreds of more than kbps.Four kinds of standards of 3G existence at present: CDMA2000, WCDMA, TD-SCDMA, WiMAX.
VPDN English is Virtual Private Dial-up Networks, is also called Virtual Private Dialup Network, is the one of VPN business, is Virtual Private Dialup Network business based on dial user, i.e. surfs the Net in dial-up access mode.Implementing of VPDN is to use tunneling technique, the data of enterprise network will be encapsulated in tunnel and be transmitted, user can realize the general headquarters' long-range management to branch by VPDN, remotely monitoring, many-sided data transfer demands such as service application, saving the communications cost of user, improve business administration operational paradigm, the most also the extension for client traffic provides well guarantee.Affiliated enterprise uses the special account number of VPDN to dial in enterprise headquarters, it is achieved local data uploading to data center of enterprise headquarters, it is achieved information sharing, the mutual and process of related service application.
Along with constantly popularizing of 3G Network, operator is proposed the VPDN business of 3G for enterprise customer to the demand of " 3G moves private network ", that is: Virtual Private Dialup Network business of based on 3G wireless access way, it is to utilize L2TP tunneling protocol, just can build on existing Dial-up Network one virtual, not by the designated lane of external interference, thus realize the similar mode using wired dedicated network and access intranet resource.
Being analyzed from above, we can use technology based on 3G VPDN private network to carry out electricity-selling system design of flowing.Use this technology to reduce firstly the expense of manpower and equipment, owing to ISP can be used to provide the ready-made network platform, greatly reduce the input on people's force-summing device；Next improves Business Processing speed, 3G network compares similar GPRS technology higher Business Processing and transmission performance, 3G VPDN system can also promote to manage the improvement of information service, power supply administration can utilize this system to improve payment flow process, from user friendly angle, improve service brand and the grade of service；3G network has the advantages that to access whenever and wherever possible, only needs a notebook computer+3G wireless network card, just can carry out sale of electricity of flowing, improve power marketing person works's efficiency.
1, system group network explanation: this system have employed B/S structure, flowing electricity-selling terminal equipment have employed " wireless network card+notebook+printer ", by browser access telecommunications 3G Radio Access Network, use the special account number of VPDN to dial in special certificate server at secure context simultaneously and carry out access authentication, safety certification obtains sales service system specialty address, Qinghai by accessing VPDN server afterwards, obtains the authority (if account number is not over certification, do not possess the function of networking) of access enterprise networks network.
In electric power side, we there is also mounted router and fire wall, fire wall has been made security strategy, only allow that the port specified accesses the wireless sale of electricity front end processor in DMZ district, wireless sale of electricity front end processor carries out data interaction with the data base of sales service system after receiving instruction, by data feedback to flowing electricity-selling terminal.
2. security of system solution is connected with intranet by radio channel due to Qinghai electric power wireless payment system, therefore design first has to ensure to access safety, it is impermissible for intranet is produced safely any impact, so solving the key that security of system problem is the flowing electricity-selling system application of 3G wireless network.
This time we have rented the 3G VPDN private network of China Telecom and have carried out research test, mainly being realized to access authentication, end to end private ownership, the security doctrine of End-to-End Security encryption when 3G disposes by proprietary APN+binding access authentication, the privately owned tunnel of L2TP, the safe encryption technology of IPSEC at secure context, concrete deployment scheme is as follows: ● proprietary APN+ binds access authentication
When the 3G wireless access carrying out flowing terminal site is disposed, the private network APN (Access Point Name) first distributed by operator.Terminal site uses 3G router to access, operator can (IMSI be the number the most uniquely identifying a mobile subscriber by the IMSI information of site user, be made up of 15 bit digital, be stored in SIM card), the account of terminal use and password configured in advance be on carrier authorization server.When the 3G router of site initiates wireless connections, only allow the legal user of binding information by user name, password AAA certification after access 3G dedicated network, prevent illegal SIM card user dial-in customer's 3G private network.
In addition; the PIN code defencive function of SIM card can be set by 3G router further; only know that the PIN password of SIM card could trigger 3G dialing, prevent the illegal operation that disabled user is carried out after getting user's SIM card, it is ensured that the use safety of SIM card.
● the privately owned tunnel of L2TP+IPSEC VPN
In order to ensure 3G access site data service transmit in operator's IP core net private ownership, we are to the VPDN business of operator application enterprise group user 3G, existing Dial-up Network builds one virtual, not by the designated lane of external interference, thus have secure access to intranet resource.
Operator can provide LAC end router and supporting AAA (Authentication checking, Authorization mandate, the Accounting book keeping operation) server of L2TP.We use a router as the LNS end of L2TP at enterprise's one-level net or two grades of net convergence-levels, and dispose an AAA server.LAC router is mainly responsible for the access authentication to 3G user, sets up L2TP tunnel with the proprietary LNS of this user owned enterprise.The AAA server of enterprise's one-level net or two grades of net convergences is mainly deposited site router and is set up username and password required when connecting.The form of user name is XX@XX.COM, and wherein the character string before@can be by user side self-defining, the@i.e. domain name of character string below.Operator's AAA server confirms the access authority of this user by domain name.Operator's AAA server is necessary consistent with the username and password of enterprise's AAA server.
End-by-end security is encrypted principle, as it was noted above, 3G technology has the cryptographic verification techniques of self, but the cryptographic verification techniques of 3G is just for wireless portion, and at IP core network part, the L2TP tunnel between LAC to LNS is not encrypted, data or in plain text transmission.And also can be through the IP network of operator in the middle of from LAC to network, in order to reach encrypted transmission end to end, need between electrical network on sale point and electric power general headquarters router, use IPSEC to realize encrypting end to end.
