Stochastic Approach in Government Service and Transactional Management Using Two-Tier Encryption-Decryption Process

Francis S. Cambaya and Albert A. Vinluan
Abstract— The Stochastic Approach in Government Service and Transactional Management Using Two-Tier Encryption-Decryption Process is designed to provide an undeterministic approach in performing encryption using Blowfish and Andvance Encryption Standard. With the help of stochastic methods namely: Poisson, Drunkards Walk and Queue, a tool for computing the cryptographic protocols to be used were developed during the process. To validate the cryptographic method to ensure security and performance for encryption and decryption, the study conducted test through visualization and experimental attacks on both AES and blowfish. The attacks are used are Scytale ciphertext-only attack, avalanche effect and Vigenère Analysis. The AES and blowfish visualization as well as the attacks were accomplished using CrypTool 2.1. Authentication and access control was applied in the developed encrypting file system through the development of a web-based application using Java. The IDE used was Netbeans 8.2. The combined use of user credentials and file encryption/decryption framework was able to implement authentication and access control in the process of government services and transactional management system.

Index Terms— Stochastic encryption, two-tier encryption-decryption, cryptography.
