Problems solved by technology

Under the current technical conditions, data storage mainly relies on network storage devices represented by various disk arrays. The data itself has no security protection measures, and there are great data security risks in the process of use.
[0007] However, the existing key management system has relatively simple functions and does not fully manage the entire life cycle of the key.
As a result, some situations cannot be handled, resulting in the inability to decrypt data and encryption failures, etc.
In addition, existing key management systems mostly use foreign-developed algorithms for encryption and decryption, causing system security to be questioned; client applications also need to participate in encryption, which increases the load on the client
In addition, the encrypted ciphertext of the same plaintext data block is the same during encryption, which makes reverse deciphering easier and reduces the security of the system

Abstract

The invention discloses a storage encryption gateway key management system and method, and relates to the technical field of network securities. The system comprises a key management center and a storage encryption gateway; the key management center is used for managing a whole life cycle of keys in a whole system, including generation, allocation, updating, destruction and recovery management of the keys; and the storage encryption gateway is used for encrypting and decrypting data, and connecting data communication between a front-end server and a storage device. Aiming at the disadvantages in the current storage encryption gateway management system that the life cycle management of the keys is incomplete and encrypted data are easily cracked and the security is low and so on, the invention provides an improved system and method, which can effectively enhance the function and security of the storage encryption gateway management system.

Description

Technical field [0001] The invention relates to the technical field of network security, in particular to a storage encryption gateway key management system and method. Background technique [0002] Gateway (Gateway), also known as network connector, protocol converter. The gateway realizes network interconnection above the network layer. It is the most complicated network interconnection device and is only used for the interconnection of two networks with different high-level protocols. The storage encryption gateway can be used for both WAN interconnection and local area network interconnection. A gateway is a computer system or device that serves as an important task for conversion. Used between two systems with different communication protocols, data formats or languages, or even completely different architectures, the gateway is a translator. Unlike the bridge that simply conveys information, the gateway repackages the received information to meet the needs of the destina...
