Timestamp is a voucher document that forms after encrypting, and it comprises three parts: the date and time of file, the digital signature of DTS are received in document, the Digital Time-stamp service (DTS:digital time stamp service) that need add timestamp.The principle of timestamp technology is with certificate particular data to be carried out the time signature, provides the time to put to the proof, and at a time has certain data to prove certain entity.TSA is the abbreviation of Time StampAuthority, and promptly time postmark authority generally is meant the trusted third party that the timestamp service is provided.The major function of TSA provides the confidential time information in the electronic signature, and this temporal information is used to prevent user's data that forge a signature before this time or after the time, carries out deceptive practices.The generative process of timestamp is as follows: the file that the user adds needs timestamp earlier forms summary with the HASH coding encrypting, then summary is carried out client's signature, data behind the signature are sent to TSA, TSA encrypts (signature) to this document after adding the date and time information of receiving in to client's signed data again, sends the user then back to.
The application process of timestamp service in remote signature system that the present invention proposes comprises the steps:
A. the user sends the request of affixing one's seal to remote signature system after editing and finishing file;
B. remote signature system data file that needs are added a cover timestamp is handled the back signature, signature adopts one-way Hash algorithm (HASH algorithm) the data file to be generated one 128 hashed value, with the user's that affixes one's seal private key this hashed value is encrypted then, form digital signature;
C. the data after remote signature system will be signed send to time stamp server TSA;
D. time stamp server TSA calculates 128 hashed value from the raw data file that receives, and then uses the user's that affixes one's seal Public key that the additional digital signature of beginning data file is decrypted again.If two hashed value is identical, time stamp server TSA just can confirm that this digital signature is remote signature system user's a signature so;
E. time stamp server TSA joins in the raw data file of receiving in the date and time information that will receive client's signed data, again this document is encrypted (signature), finishes the processing time and stabs affairs;
F. time stamp server TSA returns to remote signature system to the customer data of joining day stamp information;
G. remote signature system is verified the signature of time stamp server TSA, confirm errorless after, this timestamp service is finished;
H. remote signature system is resolved the details of timestamp service, acquisition time information;
I. remote signature system will be affixed one's seal the time from the temporal information conduct that time stamp server obtains, and charge to audit information;
J. remote signature system continue to affix one's seal, encrypt, action such as transmission;
The temporal information that views when k. the user tests actions such as chapter, audit is the temporal information of obtaining from time stamp server.
Using the method advantage of timestamp service of the present invention in remote signature system is, embed unified time relatively in the Gu Li E-seal information and stabbed information, fail safe and the reliability of time of affixing one's seal improves greatly, also solved the long-range mirror chapter in the multiple terminals skimble-scamble problem of time of affixing one's seal simultaneously.Give full play to the advance of the long-range function of affixing one's seal of E-seal technology and the unified standard time superiority of timestamp technology, and shielded limitation separately, had very high exemplary role and promotional value.
