AI Technical Summary
Technical Problem
In existing technologies, key management methods result in long key read and write operation times and fixed storage space that cannot be flexibly adjusted, leading to low operational efficiency.
Method used
By pre-building a key index table and dynamically adjusting the key storage space, the key index table is stored in NVRAM to improve read and write efficiency. This dynamic adjustment of key storage space shortens the key read and write operation time.
Benefits of technology
It effectively shortens the key read/write operation time, improves the operational efficiency of key management, and supports flexible adjustment of key storage space.

Abstract
The embodiment of the application provides a key management method and device, computer equipment and a storage medium, and belongs to the technical field of information security management. The method comprises the following steps: receiving a key reading instruction, obtaining a key reading index according to the key reading instruction; obtaining first matching index data from a pre-constructed key index table according to the key reading index, wherein the first matching index data comprises a first matching key index and a first key address offset value corresponding to the first matching key index; determining a target key reading address according to the key index table and the first key address offset value, wherein the target key reading address is used to represent a storage address of key information corresponding to the key reading index in a preset key memory; and reading the key information corresponding to the key reading index from the key memory according to the target key reading address. The embodiment of the application can shorten the key reading and writing operation time and improve the operation efficiency during key management.
