Embodiment
The present invention is mainly used in the processing of operator for electronic work order.
Usually, when taking the electronic work order mode to carry out business handling, operator at first generates an electronic work order text at the place, computer terminal; Then; The user is through outside touch pad, and perhaps other signature instruments are signed the user's signature corresponding to himself information on above-mentioned electronic work order text, and is last; Operator preserves above-mentioned user's signature and electronic work order text together, forms a single clear data of worker that has user's original signature.
Then, take method of the present invention to processings that sign electronically of the single clear data of this worker, and after data extract in sign electronically verification and then data integrity and the accuracy of assurance system among preservation and transfer of data.
Come the present invention is elaborated below in conjunction with accompanying drawing and specific embodiment.
Method embodiment:
Fig. 1 is the flow chart of anti-tamper method of the electronic signature of worker's single system of the present invention.
Method as shown in the figure, that the electronic signature of said worker's single system is anti-tamper mainly comprises two steps of electronic signature step and electronic signature extraction checking procedure.
Wherein, said electronic signature step comprises:
S101: the single clear data of the worker calculation process of making a summary is generated the first eap-message digest data;
S102: the single clear data of said worker and the first eap-message digest data are carried out single encrypt data of encryption generation worker and eap-message digest encrypt data.
Said electronic signature is extracted checking procedure and is comprised:
S201: single encrypt data of said worker and eap-message digest encrypt data are carried out decryption processing generate second worker list clear data and the second eap-message digest data;
S202: the single clear data of said second worker calculation process of making a summary is generated the 3rd eap-message digest data; And,
S203: said second eap-message digest data and the 3rd eap-message digest data are compared, whether consistent according to the result of both contrasts, judge whether said electronic signature is distorted.
Fig. 2 is the flow chart of electronic signature step of anti-tamper method of the electronic signature of worker's single system of the present invention; As shown in the figure, it mainly comprises: S101: the single clear data of the worker calculation process of making a summary is generated the first eap-message digest data; And S102: the single clear data of said worker and the first eap-message digest data are carried out single encrypt data of encryption generation worker and eap-message digest encrypt data.
According to above-mentioned steps: at first, among step S101, generate end module place in data; Operating personnel with original electronic work order file as a big text message; And can take the informative abstract technology that it is carried out digest algorithm and handle, generate eap-message digest data (to call the first eap-message digest data in the following text) corresponding to the single clear data of above-mentioned worker, and; The said first eap-message digest data pin is to some specific summary operation methods, and its value has uniqueness.
Among preferred embodiment; What the processing of the single clear data of above-mentioned worker was taked is the MD5 algorithm; Be about to the single clear data of above-mentioned worker as a big text message, adopt the MD5 algorithm computation to go out the single MD5 digest value expressly of this original worker, above-mentioned digest value is 128 message information digest value.Certainly, among this step, also can take other similar algorithm to handle.
Then; Operating personnel are in step S102; With the single clear data of above-mentioned worker with handle the first eap-message digest data that the back generates through above-mentioned steps and carry out data encryption, then, send among the data memory unit after will generating worker's list encrypt data and eap-message digest encrypt data.
And among the preferred embodiment, what take among this data encryption process is RSA Algorithm, so that the cryptographic calculation of data and decrypt operation have effect preferably.
Usually, RSA Algorithm is claimed rivest, shamir, adelman again, is meant that the user has two keys, and one is public-key cryptography, and one is private cipher key, and public-key cryptography is disclosed, and anyone can use, and private cipher key is maintained secrecy, and has only user oneself to use.
According to above-mentioned principle, the user generates end in data can use private key encryption information, and sends the other side of data receiver to, and the other side can untie ciphertext with this user's public-key cryptography.
Wherein, above-mentioned public-key cryptography and private cipher key are mutually deciphering, and have the third party anything but and can inject, and therefore, can guarantee the fail safe of the process of signing electronically.
Fig. 3 is the flow chart that checking procedure is extracted in the electronic signature of anti-tamper method of the electronic signature of worker's single system of the present invention; As shown in the figure, it mainly comprises: S201: single encrypt data of said worker and eap-message digest encrypt data are carried out decryption processing generate second worker list clear data and the second eap-message digest data; S202: the single clear data of said second worker calculation process of making a summary is generated the 3rd eap-message digest data; And, S203: said second eap-message digest data and the 3rd eap-message digest data are compared, whether consistent according to the result of both contrasts, judge whether said electronic signature is distorted.
According to above-mentioned explanation: at first, among step S201, among data memory unit (for example, electronic computer hard disk), take out through single encrypt data of the worker after the abovementioned steps processing encrypted and eap-message digest encrypt data.
Then, take the public-key cryptography corresponding to carry out decryption processing, and then obtain the single clear data of first worker and the second eap-message digest data of plaintextization with above-mentioned private cipher key to single encrypt data of worker and eap-message digest encrypt data.
For whether the electronic signature of verifying the single clear data of above-mentioned worker is distorted, we have carried out the computing of secondary summary to the single clear data of above-mentioned worker, promptly the single clear data of said second worker calculation process of making a summary are generated the 3rd eap-message digest data; Among this step, we take be with step S101 in duplicate summary operation method, for example, take the MD5 algorithm.
Then, we get into step S203: said second eap-message digest data and the 3rd eap-message digest data are compared, because according to the principle of MD5 algorithm, identical data must obtain identical MD5 informative abstract value.Therefore, as long as whether whether we consistent according to the result of both contrasts just can judge said electronic signature comparatively like a cork and distorted.
And, taking after such method, all people that are authorized to reading file can verify to have good technical effect to the integrality of document.
