Performance Analysis of Deterministic Finite Automata and Turing Machine Using JFLAP Tool

Abstract

In real life, the increased data accessing speed and data storage ability is required by most of the machinery fields. However, the real-world problems can be studied effectively with the combination of scientific computational techniques with the mathematical models. Automata theory is known to be the popular mathematical model. Towards most of the software and hardware related applications, the computational methods are analyzed and designed using significant automata theory concepts (likely, pushdown automata (PDA), Turing machines (TMs) and finite automata (FA)). Hence, the conventional lecture-driven style has attracted the reflective preferences of learners using these abstract natured concepts. But the lecture-driven teaching style has less motivated the computer engineering learners. In order to learn automata theory and computational models, we introduce the PDA and TM in a virtual platform. However, this work has motivated the improvement of longitudinal experimental validation and learning using the modern technology. Java Formal Languages and Automata Package (JFLAP) tool is used to write our simulators in JAVA language and the results are obtained from each machine through simulating the input strings.

Preventing Data Leakage in Cloud Servers through Watermarking and Encryption Techniques

“…Awadallah, Ruba, et.al,… [1]Which create SHA-256 chain records to represent the database schema and distribute the data across multiple cloud service providers to simulate decentralization.When a client submits a query, the contracted cloud service providers must update their databases and create an RDB-signature to confirm their agreement on the outcome [25]. The analysis suggests that this approach is cost-effective and does not require significant additional energy usage.Overall, the proposed approach seeks to address the security concerns associated with cloudbased databases by leveraging blockchain technology to create a decentralized and secure system that allows for reliable authentication and monitoring of data modifications.…”
