Analysis of Security Algorithms for a Distributed Database

We analyzed the security of a database considering the environment of distributed systems, there are several security mechanisms that are applied to the different types of data that are saved; this research identifies several problems for mitigating the security of a distributed database. The objective is to define a basic scheme and an abstract algorithm through algorithms using flowchart techniques for a security process in a DDB. The deductive method and the exploratory investigation were used to analyze the information of the articles of the reference. It resulted in a basic structure based on a three-level architecture, with 3DES encryption algorithm applied to the request and response; SQL-based encryption for data processing; FPE encryption algorithm for storage in the database; the scheme was presented with its scope and possible limitations; and a prototype of an abstract algorithm expressed with flowchart techniques was obtained. It was concluded that the basic scheme and abstract algorithm presented as an alternative to control access to resources, to provide improved security in a distributed database.
