Embodiment 1

[0019] like figure 1 As shown, the embodiment of the present invention provides a server-side secure file management method, including:

[0020] Step 101, the service server encrypts the security file with the management key to obtain the encrypted file.

[0021] In this embodiment, the process of encrypting the security file in step 101 may be to directly encrypt the security file with the management key to obtain the encrypted file; After encryption, the once-encrypted file is encrypted with the management key to obtain the encrypted file; the business server can also use the management key and other encryption methods to encrypt the security file, which will not be repeated here. Wherein, the management key is configured by the service management device, and the management key is generated by concatenating the service key of the business server and a randomly generated service random key. Preferably, the service random key is valid once.

[0022] Step 102, the service se...

Embodiment 2

[0046] like image 3 As shown, the embodiment of the present invention provides a server-side security file management device, including:

[0047] The encryption module 301 is used to encrypt the security file by using the management key to obtain the encrypted file; the management key is configured by the service management device, and the management key is generated by splicing the service key and a randomly generated service random key;

[0048] The storage module 302 is connected with the encryption module and used for storing encrypted files.

[0049] In this embodiment, the process of implementing secure file management on the server side through the encryption module 301 and the storage module 302 is similar to that provided in Embodiment 1 of the present invention, and will not be repeated here.

[0050] The technical solution provided by the embodiment of the present invention implements server-side security file management through encrypted storage of security files...

Embodiment 3

[0052] like Figure 4 As shown, the embodiment of the present invention provides a server-side security file management system, including:

[0053] The service management device 401 is configured to configure a management key, which is generated by concatenating the service key of the business server and a randomly generated service random key;

[0054] The service server 402 is connected with the service management device, and is used to encrypt the security file with the management key to obtain the encrypted file; and store the encrypted file.

[0055] In this embodiment, the process of implementing secure file management on the server side through the service management device and the service server is similar to that provided in Embodiment 1 of the present invention, and will not be repeated here. The structure of the service server is similar to the structure of the server-side secure file management device provided in Embodiment 2 of the present invention, and will not...

Abstract

The invention discloses a server-side security file management method, device and system, and relates to the field of information security. It was invented to solve the problem of relatively concentrated risk and low security in the prior art because the private key is uniformly stored in one chip. The technical solution provided by the embodiment of the present invention includes: the business server encrypts the security file with a management key to obtain the encrypted file; the management key is configured by a service management device, and the management key is configured by the service key of the business server; key and a randomly generated service random key are concatenated; the service server stores the encrypted file.

Description

technical field [0001] The present invention relates to the field of information security, in particular to a server-side security file management method, device and system. Background technique [0002] An encryption machine is a host encryption device used to provide security services such as encryption and digital signatures for application systems. In the prior art, the encryption machine generally saves the security files uniformly through the chip. [0003] However, due to the unified storage of security files in one chip, the risk is relatively concentrated and the security is low. Contents of the invention [0004] The purpose of the present invention is to provide a server-side security file management method, device and system, which can reduce risks and improve security. [0005] On the one hand, the embodiment of the present invention provides a server-side security file management method, including: the business server uses a management key to encrypt the se...
