Problems solved by technology

[0003] Usually, the application of encryption technology in such a redundant system has the following difficulties: if different platforms implement the same encryption algorithm, different sources of random number seeds will result in different secret keys, resulting in different encryption results. The output result cannot be compared and judged

Embodiment 1

[0033] Embodiment one, such as figure 1 As shown, a device for obtaining consistent encryption and decryption results in a synchronous redundant system is used in an information control system with high security requirements, including several synchronously running homogeneous or heterogeneous redundant executive bodies 10 , scheduler 20 and encryption operator 30;

[0034] The redundant execution body 10 is connected with the scheduler and is used to execute the application program. Each redundant execution body is equivalent in function and can be homogeneous or heterogeneous in structure, and runs a series of application programs on it , according to the input of the scheduler, perform task processing.

[0035] The scheduler 20 is used for various management of redundant execution bodies, input and output agents, and other related operations, such as receiving external input and distributing input data to each redundant execution body; and judging the addition of redundant...

Abstract

The invention relates to the technical field of encryption protection and the technical field of system architecture which adopts redundancy design and needs redundancy executor comparison results, inparticular to a device for obtaining consistent encryption and decryption results in a synchronous redundancy system, which comprises a plurality of isomorphic or heterogeneous redundancy executors which run synchronously, a scheduler and an encryption arithmetic unit, the redundant executor is used for executing the application program and outputting an operation result to the scheduler; the dispatcher is used for managing each item of the redundant executor and inputting and outputting an agent; and the encryption arithmetic unit is used for carrying out encryption and decryption operationon the input data stream and returning a data encryption and decryption result to the scheduler. The invention further relates to a method for obtaining the consistent encryption and decryption resultin the synchronous redundancy system. According to the invention, the consistent encryption behavior on the redundant executor is realized, and the encryption intermediate results are consistent, sothat the final output result can be compared and judged.

Description

technical field [0001] The present invention relates to the technical field of encryption protection and the technical field of system architecture that adopts redundant design and requires comparison results of redundant executives, and in particular relates to a device and method for obtaining consistent encryption and decryption results in a synchronous redundant system. Background technique [0002] In the case of high system security, system redundancy design is usually adopted, and multiple homogeneous or heterogeneous task executives are used to process tasks synchronously, and the accuracy of the overall output of the system is improved by comparing and judging the output of the executive , and improve the system's ability to resist attacks. [0003] Usually, the application of encryption technology in such a redundant system has the following difficulties: if different platforms implement the same encryption algorithm, different sources of random number seeds will r...
