Multi-core implementation of the symmetric cryptography algorithms in the measurement system

The paper presents the implementation of symmetric cryptography algorithms in the measurement system, where the virtual instruments equipped with the multi-core processors are used to process large amounts of data. The security requirement in such systems is first considered, then the possible solutions to ensure reliable data transmission are proposed. The Advanced Encryption Algorithm (AES) is described in detail as the example of the strong encryption and decryption scheme. Its modifications to take utilize the multi-core processor are then presented. Implementation of the latter in the virtual instrument (VI) working under the Real-Time (RT) mode is described in detail. Finally, required tests are conducted to confirm validity and efficiency of the proposed solution. Comparison between the traditional and modified algorithm is performed to draw conclusions about the possible advantages and applications of such algorithms.
