Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flowchart of an implementation method of an application electronic signature service system in a cloud computing environment according to an embodiment of the present invention. As shown in fig. 1, the method includes:
step S101, deploying an electronic signature service system in a cloud computing environment, and accessing each application system in the cloud computing environment to the electronic signature service system through an application interface.
Step S102, when each application system in the cloud computing environment sends a signature request to an electronic signature service system, the electronic signature service system converts electronic data needing to be signed into a form of a two-dimensional code picture; the two-dimensional code picture is scanned through the smart phone, the two-dimensional code data are obtained to confirm information, and the confirmed error-free information is sent to the electronic signature service system.
Preferably, the two-dimensional code data includes: original data or summary data to be signed; the summary data is generated after the electronic signature service system performs summary operation on the original data to be signed.
It should be noted that, by means of the traditional electronic signature data processing flow and the two-dimensional code scanning technology, the invention enables the user to more conveniently carry out the interaction of the electronic signature through the mobile equipment, and the safe and reliable electronic signature in the technology is completed; meanwhile, on the basis of keeping the safety requirements and the service flow of the original service system, a user has better interactive experience.
And step S103, the electronic signature service system encrypts the confirmed electronic data by using a Hash code to form a summary by adopting a digital time stamp technology, adds the date and time information of the received summary into the summary and then carries out electronic signature.
Preferably, the electronic signature comprises: the electronic signature service system performs HASH operation on the submitted electronic data by default to form a HASH value; encrypting the HASH value by using a private key corresponding to the digital certificate of the operator to form an electronic signature value; and the electronic signature adopts RSA algorithm or national cryptographic SSF33 algorithm.
It should be noted that the digital time stamp service (DTS) is a network security service item provided by a special organization, and the time-stamp is a voucher document formed after encryption, and includes three parts: a digest (digest) of the file to be time stamped; the date and time when the DTS received the file; digital signature of DTS. Time stamping is a ubiquitous element of transactions, particularly business processes and business transactions, which provide queryable evidence of when a business process or business transaction occurs. By recording these times in the document, it can be made necessary evidence due to many unique attributes (e.g., the specificity, format, etc. of the ink in the document). The related aspect can prove that a certain file is generated at a certain time and has the following characteristics: non-repudiation and auditability; uniformity and non-intermittency; authenticity and integrity; and (4) reliable storage.
It should be noted that, the implementation of the electronic signature technology requires asymmetric encryption (RSA algorithm) and a message digest (HASH algorithm). The asymmetric encryption means that a user has two keys, one is a public key and the other is a private key, the public key is public and can be used by anyone, the private key is secret and can be used by only the user, and the public key and the private key are in a corresponding relation. The user can encrypt information by using the public key of the other party and transmit the information to the other party, and the other party uses the private key of the other party to unlock the ciphertext. The public and private keys are mutually decrypted and absolutely no third party can be inserted. The message abstract utilizes the HASH algorithm to operate any information to be transmitted to generate a 128-bit message abstract, and different contents of information can generate different message abstracts, so that the message abstract becomes a 'fingerprint' of electronic information. The electronic signature of the electronic information can be realized by the asymmetric encryption technology and the message digest technology.
And step S104, the electronic signature service system adopts a digital watermark technology to embed the electronic data after electronic signature into the electronic data to form signature watermark electronic data.
Preferably, the signature watermark comprises: text or pictures.
It should be noted that, in the Digital Watermarking (Digital Watermarking) technology, some identification information (i.e. Digital watermark) is directly embedded in a Digital carrier (including multimedia, document, software, etc.) or indirectly represented (modifying the structure of a specific area), and the use value of the original carrier is not affected, and the identification information is not easily ascertained and modified again. But can be identified and recognized by the producer. The information hidden in the carrier can achieve the purposes of confirming content creators and purchasers, transmitting secret information, judging whether the carrier is tampered or not and the like. Digital watermarking is an effective method for protecting information safety, realizing anti-counterfeiting tracing and copyright protection, and is an important branch and research direction in the field of information hiding technology research.
And step S105, the electronic signature service system dynamically generates a user encryption key by adopting a data domestic cryptographic technology, encrypts the electronic data of the signature watermark and returns the electronic data of the signature watermark to each application system in the cloud computing environment.
It should be noted that, the implementation method of the application electronic signature service system in the cloud computing environment provided by the embodiment of the present invention further includes: and carrying out decryption processing on the electronic data of the electronic signature and carrying out watermark extraction on the electronic data of the signature watermark.
In summary, the invention realizes the flexible application of the electronic signature service system in the cloud computing environment by fusing the technologies of cloud computing, two-dimensional codes, timestamps, data encryption, electronic signatures, digital watermarks, identity authentication and the like, so as to solve the problems of inconvenient use and low efficiency caused by the need of plugging a smart card in the traditional electronic signature. Furthermore, through a two-dimensional code scanning technology, a user can conveniently interact with the electronic signature through mobile equipment, and the electronic signature which is safe and reliable technically is completed; meanwhile, on the basis of keeping the safety requirements and the service flow of the original service system, a user has better interactive experience. Furthermore, the electronic signature with time accuracy is realized by combining the digital timestamp technology and the electronic signature technology, and by combining the digital watermark technology, safety protection measures are implemented again on the basis of the electronic signature to prevent data from being copied and abused, namely, the information safety protection capability of an application system in cloud computing is enhanced, identity counterfeiting and illegal tampering of data information can be effectively prevented, the integrity of the data information is protected, and information safety applications such as identity authentication, data integrity protection and the like are provided for a cloud computing application service system.
The above disclosure is only a few specific embodiments of the present invention, and those skilled in the art can make various modifications and variations of the present invention without departing from the spirit and scope of the present invention, and it is intended that the present invention encompass these modifications and variations as well as others within the scope of the appended claims and their equivalents.
