System Analysis and Example of Using SHA-512 Hash Functions to Protect Students' Personal Data on Educational Platforms

In modern conditions the use of hash functions for the protection of personal data plays an applied and fundamental role in the creation of educational environments on computing systems using cryptographic methods. To effectively solve this topical problem, the protection functions simultaneously pass the data of limited length to the consumer, which leads to the reduction and fixation of the size of the information signal for interception. Thus, software applications developed on the basis of these cryptographic functions include the following parameters, namely algorithms for checking the integrity of programs, students' personal data, as well as specialized algorithms for authorization and authentication. As large volumes of critical data circulate in today's computing environment and need to be processed quickly, the throughput of the hash functions used becomes a key factor. This paper proposes an efficient implementation of SHA-512 on a developed software application and avalanche effect has been investigated.
