Problems solved by technology

In recent years, with the continuous development of the Linux kernel, more and more types of hardware drivers, file systems, scheduling modes, application software, etc. are supported, which makes the Linux kernel and distribution become huge, which reduces the startup speed and increases the attack surface. get bigger
In the cryptographic device, even though the Linux system has undergone a series of cuts, there are still some parts that are closely integrated with the system functional components that cannot be cut, which will affect the startup speed of the cryptographic device and increase the security risk of data

Abstract

The invention provides a password unit creation method and device, a data processing method and device and electronic equipment. The creation method comprises the steps of obtaining a password component for executing a password processing operation; according to the dependency relationship between the password component and a dependency component, obtaining each type of target dependency componentcorresponding to the password component; and packaging the password component and each type of target dependency component into a mirror image file representing a password unit installation package through a static link by using a construction tool. According to the scheme, the password component and the target dependency component are independent and then packaged into the mirror image file in astatic link mode, and the mirror image file can achieve corresponding password operation during running. Based on this, the capacity of the password unit is small, the number of attack surfaces can be reduced to improve the security of data, and in addition, due to the small capacity, the starting speed and the recycling speed when a password service function is used can be increased.

Description

technical field [0001] The present invention relates to the technical field of computer cryptography, in particular to a cryptographic unit creation method, data processing method, device and electronic equipment. Background technique [0002] In the computer field, in order to improve data security, cryptographic devices are generally required to perform corresponding encryption or decryption operations on transmitted data. Currently, cryptographic devices rely on the Linux system to provide cryptographic functions through dedicated hardware. The degree of coupling between the cryptographic device and the Linux system is high, and the Linux system itself is not used in the cryptographic field. In recent years, with the continuous development of the Linux kernel, more and more types of hardware drivers, file systems, scheduling modes, application software, etc. are supported, which makes the Linux kernel and distribution become huge, which reduces the startup speed and incr...
