description: Theme of the final qualification work: "The use of critographic tools in nosql databases". This work is devoted to increasing data security in NoSQL storage by developing a data encryption mechanism for the subsequent implementation of secure storage. Tasks that were solved during the study: 1. Analysis of existing solutions that provide cryptographic protection of a DBMS. 2. Development of cryptographically secure storage architecture based on existing NoSQL solutions. 3. The choice of cryptographic algorithms for implementation in the DBMS. 4. Assessment of the impact on the performance of the proposed solutions. As a result, in this thesis, the requirements for the encryption system in the DBMS are proposed. The analysis and comparison of the functionality of existing secure DBMSs is performed. The comparative analysis of NoSQL DBMS types is given. The architectures from the point of view of using encryption in the DBMS, approaches to the joint use of several cryptosystems are investigated and evaluated. Cryptosystems with homomorphic properties are analyzed and evaluated. A prototype non-relational DBMS of the âfamily of columnsâ type has been developed, which uses encryption at the application level to protect user data. The ability to fulfill the necessary requests and the possibility of implementing additional structures that accelerate the execution of the request are verified. Estimated query execution time and the amount of encrypted data in the implemented prototype.
