System and method for safe sharing dynamic memory of multi-application space

Abstract

The invention relates to a safe sharing dynamic memory system used for multiple applications and a method thereof, which pertains to the technical field of information safety and is especially applicable to exchanging information safely among multiple systems. The system comprises a sharing memory pool, a memory block and an access control module; the sharing memory pool is a multi-array sharing memory pool; the sharing memory pool is a virtual two-dimensional multi-array memory space; each memory space can be allocated by size dynamically and specified with access privileges, and adopt different cipherkey algorithms so as to ensure the completeness and confidentiality of data in the memory and achieve data sharing among multiple applications. The method adopted in the system comprises procedures of establishing the sharing memory pool, writing data, reading data, writing the data into the sharing memory and decrypting the data. The system and the method of the invention have the advantages of ensuring the completeness and confidentiality of the data in the memory, achieving safe, convenient and flexible data sharing among multiple applications and also being capable of serving as a basic facility to realize safe information exchanging among multiple systems.

Description

technical field [0001] The invention relates to a system and method for securely sharing dynamic memory between multiple applications, belongs to the technical field of information security, and is particularly suitable for realizing secure exchange of information among multiple systems. Background technique [0002] Data sharing among multiple applications is a very important and practical technology. The development and design of large and medium-sized software is mostly completed by the cooperation of many programmers. Usually, a programmer is only responsible for the development of one or several modules. These modules can be dynamic link libraries, applications or other programs. A program component of the form. These independently developed program modules ultimately need to be run as a whole, that is, to form a system. During the operation of the system, these modules often need to frequently exchange and share data. For dynamic link libraries and their calling appli...
