Secured and Privacy in Exam Cell Management System Using Blockchain Mechanism with Advanced Encryption Standard (AES) Algorithm

This study proposes a novel approach to enhance the security and privacy of Exam Cell Management Systems (ECMS) by integrating blockchain technology with the Advanced Encryption Standard (AES) algorithm. Traditional systems face challenges such as data breaches and unauthorized access, necessitating innovative solutions. Our proposed system utilizes blockchain's decentralized and immutable nature to securely record and verify examination-related transactions. Each transaction is encrypted using AES before being added to the blockchain, ensuring confidentiality and tamper-proofing. The decentralized nature of blockchain enhances transparency and accountability, while AES encryption provides robust data protection. Experimental results demonstrate significant improvements in data security, privacy, and integrity compared to traditional systems. This approach offers a promising solution for educational institutions to mitigate the risks associated with data breaches and unauthorized access, thereby ensuring the integrity and trustworthiness of the examination process.
