Strengthening Digital Security through a Hybrid Encryption Algorithm for Messages on WhatsApp

연구 분야: Infrastructure

학회: SN Computer Science

The primary objective of this study is to develop a cryptographic algorithm that integrates the Caesar and Vernam encryption methods, further secured through key encryption using a Hash function, aimed at enhancing message security in communication channels like WhatsApp ChatBot. The methodology involved designing and implementing the algorithm within a WhatsApp ChatBot to encrypt and decrypt messages directly within the platform, thereby demonstrating its practicality in real-world applications. Comparative analysis was conducted to evaluate the algorithm's performance against other cryptographic methods, revealing a substantial improvement in data security. Specifically, the proposed approach showed superior resistance to unauthorized access and cryptographic attacks, outperforming methods such as ROT13 combined with Vernam and Stream Cipher, or modified Caesar techniques. The results also confirmed the algorithm’s capacity to protect message integrity and confidentiality effectively, addressing the challenges of secure digital communication. In conclusion, the findings validate the potential of the proposed algorithm as a robust solution for safeguarding data in messaging platforms. However, to fully explore its scalability and practical deployment, further research involving detailed simulations, real-world testing, and applicability in broader information security contexts is recommended. This underscores the importance of continuous innovation in cryptographic methods to enhance digital security and protect sensitive communications on platforms like WhatsApp.
