ANALYSIS OF THE USE OF THE HIGHLY EFFECTIVE IMPLEMENTATION OF THE SHA-512 HASH FUNCTIONS FOR THE DEVELOPMENT OF SOFTWARE SYSTEMS

Hashing functions play an applied and fundamental role in the current protection of programs and data by cryptography techniques. Typically, these security features transmit latency data at the same time, producing a small and fixed-size signal. Along with an avalanche-like growing volume of data requiring quick validation, the hash function throughput is becoming a key factor. According to scientific research published in the technical literature, one of the fastest implementations of SHA-512 is the SHA-2 implementation, which provides bandwidth of the algorithm over 1550 Mbps, but is also faster such as the Whirlpool where bandwidths exceed 4896 Mbps At present, many papers have been published discussing the hardware implementation of the SHA-512. All considered implementations are usually aimed at high bandwidth or efficient use of computing resources. In general, it is impossible to know in advance which choice of functional design for this component will be the best in achieving the specific design purpose. After implementation and implementation of the algorithm with different components, it was possible to carry out system analysis and comment on the quality of this implementation, since the goal relates to the achievement of high bandwidth or low overall computing power. We systematized the results of all the calculations performed and analyzed each implementation separately. A detailed description of the stages of the expansion and compression of messages. Similarly, at different stages and refers to the stage of update hash, but its implementation is not always clearly defined. One of the reasons to skip the details of the previous stage and the stage of the hash update is that it assumes that these steps will be implemented in such a way as to minimize the negative impact on it. The data mixing function in the article does not claim to be the highest bandwidth of the algorithm, but it proved to be sufficiently stable for third-party decoding. Summarizing our research in the field of cryptographic protection by various methods, we can state that the application developed on the basis of the SHA-512 algorithm application software corresponds to the following technical parameters, namely verification of the integrity of programs and data and a sufficiently reliable authentication algorithm.
