Embodiment
The safety of the electricity consumption situation being monitored and under the mode of not having the card sale of electricity, being guaranteed load value data for the ease of electric power enterprise, in embodiments of the present invention, when carrying out communication between the network equipment of ammeter and electricity bill control data are encrypted, when ammeter need be supplemented with money, for the network communication signal of supplementing order with money that comprises that receives, it is correct to use earlier the decipherment algorithm of setting to confirm that this supplements order with money, supplement the Stored Value information that the ammeter record is revised in order with money according to this again, guarantee to supplement with money data security in the order with this.The application scenarios that the embodiment of the invention is considered be have card sale of electricity and and do not have the mode that the card sale of electricity combines, promptly power consumer can use IC-card to purchase electricity and to ammeter payment, also can utilize the no card sale of electricity business of Utilities Electric Co..In embodiments of the present invention, not having card sale of electricity business realizes according to flow process shown in Figure 2.In flow process shown in Figure 2, can be between electricity bill control center and the concentrator by receiving and sending messages by dedicated network or GPRS, can receive and send messages by the power line carrier mode when using network communication between concentrator and the ammeter, also can use wireless digital radio station communication signal, global mobile communication system/general grouping wireless service signal or 485 interface communication signals.Below be that example describes to receive and send messages by the power line carrier mode between concentrator and the ammeter.
Step 01: telephone system or internet system send the information that user's initiation is paid the fees to the electricity bill control center.This information has been specified the ammeter that need supplement with money.In this step, the user initiates to pay the fees by phone or internet.Comprise the information that is used to specify ammeter in the information that initiation is paid the fees, for example provided the identification information of ammeter.Also include the amount of supplementing with money in the information that initiation is paid the fees, for example the electric degree number or the amount of money to ammeter.
Step 02: the mind-set concentrator sends pre-charging information in the electricity bill control.Ammeter is determined according to the information that the user provides in the electricity bill control center in this step, determines concentrator according to the corresponding relation of ammeter of preserving in the database and concentrator again, can send pre-charging information to concentrator by dedicated network or GPRS then.
Step 03: concentrator sends pre-charging information to ammeter.Specifically be that pre-charging information is modulated into carrier signal, send to ammeter then.
Step 04: ammeter sends to concentrator and supplements response message in advance with money.Specifically be that ammeter is read last charging information, what comprise ammeter in this charging information supplements number of times with money, supplements information such as time the residual electricity number of degrees, the last time that can also comprise ammeter in addition with money.And in this step, ammeter also sends relevant information to concentrator.The relevant information here is used to generate ciphertext, is illustrated hereinafter for the particular content of this relevant information.After this step was finished, ammeter entered the wait carrier wave and supplements state with money.
Step 05: concentrator sends to the electricity bill control center and supplements response message in advance with money.
Step 06: the electricity bill control center judges according to supplementing response message with money in advance whether ammeter can supplement with money, if can then carry out step 10, otherwise enters step 07 and step 08.
If the user is in the preceding card mode of having used when once purchasing electricity, complete charge, in card, stored the electric degree number of respective numbers and electricity bill control central record this paying be the user which time paid, this user will block the insertion ammeter then, supplementing with money in advance in the response message so, supplementing number of times with money and equal the number of times of paying; Otherwise not inserting ammeter if the user will block, promptly is not ammeter payment, is supplementing with money in advance in the response message so, supplements number of times with money and lacks 1 than the paying number of times.Therefore the electricity bill control center can be identical according to the paying number of times before this is supplemented with money at ammeter of supplementing number of times and preservation with money of supplementing with money in advance in the response message, confirms that ammeter can supplement with money.
Step 07: the mind-set user uses in the electricity bill control telephone system or internet system are sent information, and its content is that ammeter can not be supplemented with money.
Step 08: the mind-set concentrator sends cancellation and supplements order with money in the electricity bill control.Enter step 09 then.This step can be before or after step 07.
Step 09: concentrator sends cancellation to ammeter and supplements order with money.
Step 10: the electricity bill control center generates supplements order with money.This supplement with money order at be the ammeter of appointment in the step 01.In this step, the electricity bill control center is included in according to the generation of the relevant information in the step 04 ciphertext and supplements with money in the order.
Step 11: the mind-set concentrator sends and supplements order with money in the electricity bill control.The electricity bill control center is according to the ammeter of preserving and the corresponding relation of concentrator in this step, search supplement with money order at the concentrator of ammeter correspondence, supplement order with money to the concentrator transmission that finds again.
Step 12: concentrator sends to ammeter and supplements order with money.Specifically be to be modulated into carrier signal and to send to ammeter then with supplementing order with money.
Step 13: order is supplemented in the ammeter checking with money.If it is correct to supplement order with money, then enters step 14, otherwise enter step 17.How further specify ammeter hereinafter verifies and supplements order with money.
Step 14: ammeter is supplemented with money according to supplementing order with money.Specifically be to revise the electric weight that writes down in the ammeter according to the amount of supplementing with money of supplementing with money in the order.
Step 15: ammeter sends the response message of successful recharging to concentrator.This information is modulated into carrier information equally and sends then.
Step 16: concentrator is sent to the electricity bill control center with the response message of successful recharging.
Step 17: ammeter sends information to concentrator, and its content is incorrect for supplementing order with money.Being modulated into carrier information equally sends then.
Step 18: concentrator is sent to the electricity bill control center with information.
Below in conjunction with step 04 and step 13, further specify guaranteeing the mode that data security adopted of supplementing order with money in the embodiment of the invention.
A kind of mode is for the relevant information in the step 04, can be the ammeter described in this step supplement number of times with money, supplement response message as can be seen in this case in advance with money and also can be used to generate ciphertext, so need not to send separately the relevant information that is used to generate ciphertext.When the electricity bill control center generates ciphertext, the number of times of supplementing with money of ammeter is encrypted and obtained ciphertext according to the cryptographic algorithm of setting.When ammeter is verified supplementing order with money in step 13, use the decipherment algorithm of setting earlier, calculate the comparison ciphertext according to the number of times of self preserving of supplementing with money.The decipherment algorithm that the cryptographic algorithm at electricity bill control center and ammeter use should be identical or consistent, and promptly the two result who obtains at identical data computation should be identical.So, if the comparison ciphertext is identical with ciphertext, illustrate supplement with money in the order supplement with money in number of times and the ammeter to supplement number of times with money identical, can think that this supplements order with money is to be used for supplementing with money of this ammeter, be the correct order of supplementing with money.Use algorithm to encrypt, read artificially and write in certain ammeter, thereby and supplement this with money order and intercept and capture or duplicate and import this certain ammeter and cause illegally and supplement with money for fear of the information of supplementing number of times with money of supplementing with money in the order to supplementing number of times with money.Cryptographic algorithm and decipherment algorithm can be provided by the electricity bill control center.
Another kind of mode is for the relevant information in the step 04, can be the random number that ammeter generates and preserves.This random number also can be included in and supplement with money in the response message.When the electricity bill control center generates ciphertext, this random number encryption is obtained ciphertext according to the cryptographic algorithm of setting.When ammeter was verified supplementing order with money in step 13, the decipherment algorithm of use setting calculated the comparison ciphertext then with itself and ciphertext contrast to random number, and then to supplement order with money correct as if identical.The random number that this moment, ammeter used can only be the random number of preserving when generating random number, and this random number lost efficacy after obtaining comparing ciphertext, can be with its deletion.The order of supplementing with money that this as can be seen mode can be avoided mailing to current ammeter is used to other ammeters, because other ammeters are different with the random number that current ammeter generates, the comparison ciphertext that other ammeters obtain is also different with ciphertext in supplementing order with money.
The third mode is for being used in combination of above-mentioned dual mode, and what comprise described ammeter in the relevant information in step 04 simultaneously supplements number of times and random number with money.This mode compare in first kind of mode, can avoid the number of times of supplementing with money that number of times equals to be supplemented with money ammeter just of supplementing with money of other ammeters, thereby also can utilize the situation of order of supplementing with money that ammeter receives of being supplemented with money for other ammeter payments.Compare in the second way, can avoid random number to be read and imitate the random number that generates into other ammeters by some technological means, thereby also can utilize the situation of order of supplementing with money that ammeter receives of being supplemented with money for other ammeter payments.
For above-mentioned three kinds of modes, the amount of supplementing with money of ammeter can also be added in the ciphertext.When the calculating of step 13 comparison ciphertext, according to random number and/or supplement number of times with money, and the amount of supplementing with money is calculated.Can avoid like this after order is correctly supplemented in checking with money, import ammeter again supplementing the order modification amount of supplementing with money information wherein with money.
