Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] see Figure 1-2 , the present invention provides a technical solution: a method for encrypting national secrets using RDMA PSN, comprising an encryption step and a decryption step, characterized in that: the encryption steps are as follows:

[0023] Step 1. When the RDMA data needs to be encrypted, the user provides an SM4 key KEY_A;

[0024] Step 2. Superimpose the RDMA PSN and KEY_A in step 1, and then use the SM3 cryptographic hash operation to obta...

Abstract

The invention relates to the field related to data security, in particular to a method for performing national secret encryption by using RDMA PSN, which comprises an encryption step and a decryption step, and comprises the following steps of: encrypting a data part in RDMA by using SM4, superposing the PSN and a KEY_A of the RDMA, and obtaining a key encryption key KEYB by using a low 128 bit of an SM3 password hash operation result, thereby effectively encrypting the data in the RDMA; meanwhile, when the user needs to switch the key KEYA, assigning which PSN starts to use a new key KEYA at the same time, so that the effect of switching the key without interrupting transmission is achieved, data are better protected, the key can be circularly and automatically switched according to the PSN, the data are better protected, and the confidentiality is improved.

Description

technical field [0001] The invention relates to the field related to data security, in particular to a method for encrypting national secrets by using RDMA PSN. Background technique [0002] The full name of RDMA (Remote Direct Memory Access) technology is Remote Direct Data Access, which was created to solve the delay of server-side data processing in network transmission. Among them, in the RDMA protocol, MR (Memory Region) is used to complete the registration during RDMA access The virtual contiguous memory area accessed on the other side is used to manage local access and remote access of memory; when MW (Memory Window) RDMA accesses, some resources can be allocated in the allocated and bound MR for remote access Area. [0003] The existing RDMA does not specify a special encryption method, and the data is transmitted in plain text, which is extremely easy to be eavesdropped and tampered with. In view of this situation, a method of using RDMA PSN for national secret enc...
