Embodiment Construction

[0042] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0043] figure 1 It is a schematic structural diagram of an implementation environment shown according to an exemplary embodiment. The implementation environment may include a client 110 , a server 120 and a user terminal 130 .

[0044] The client 110 may be a computing device capable of providing the server 120 with information to be signed, and providing the signed information to th...

Abstract

The disclosure relates to a file signature method. The method is applied to a client and the method comprises the steps as follows: performing abstract calculation on a target file to obtain an abstract value of the target file; transmitting the abstract value to a server, wherein the abstract value is used by the server to encrypt the abstract value; receiving an encrypted abstract value from the server; and combining the encrypted abstract value into the target file. Therefore, the problem that the client needs to upload the whole target file to the server for file signature is solved, and the effects of reducing the information transmission amount between the client and the server and improving signature efficiency are achieved.

Description

technical field [0001] The disclosure relates to the field of computers, in particular to a file signature method and device. Background technique [0002] File signature technology can enhance the integrity and security of file transmission, and has been widely used in information transmission, information security, transaction services and other fields. File signature technology is based on client / server (C / S) architecture. In related technologies, the client needs to upload the entire file to be signed to the server, so that the server can sign it. Since the entire file to be signed needs to be uploaded, the transmission speed between the client and the server is slow, and the signature efficiency is low. Contents of the invention [0003] In order to overcome the problems existing in related technologies, the present disclosure provides a file signature method and device. [0004] According to the first aspect of an embodiment of the present disclosure, there is pro...
