Design of Secure Electronic Disposition Applications by Applying Blowfish, SHA-512, and RSA Digital Signature Algorithms to Government Institution

摘要

Many Government institutions still applies manual dispositions so that there are still some obstacles including the speed of delivery, accessibility, search, and the absence of security against disposition so that the disposition is prone to damage. In this study an electronic secure disposition application will be developed in accordance with the Regulation of the Minister of State for Administrative Reform and Bureaucratic Reform number 6 of 2011 concerning Regulation of Electronic Service Manuscripts to overcome manual disposition problems in Government Institution. The application will apply the Blowfish algorithm as its encryption method. and digital signatures with SHA-512 hash functions and RSA digital signatures in the attached file. The methodology used is Prototyping and modeling with UML (Unified Modeling Language). The results obtained in the form of a safe electronic disposition system are called Electronic Disposition Information System (e-disposition) of government institution. The system can meet the management of dispositions according to the needs in Government institution with guaranteed confidentiality, data integrity, authentication, and non-denial.
