Enhancing Security in Blockchain-Based System with Sharding via Advanced Encryption Standard (AES) Algorithm

Blockchain technology has offered a decentralized and gained widespread adoption in various domains of immutable ledger. However, as blockchain networks grow, they face challenges related to scalability and security. However, as blockchain networks continue to scale, the need for efficient solutions to maintain security and scalability becomes increasingly critical. A potential way of solving these problems is sharding, an approach that breaks the blockchain network into smaller, interconnected shards. This paper explores the enhancement of security in blockchain-based systems by implementing sharding with the Advanced Encryption Standard (AES) algorithm. Sharding effectively partitions the blockchain network, allowing multiple transactions concurrently. While this approach can improve scalability, it also introduces new security considerations, such as the need to secure inter-shard communication and protect sensitive data within each shard. AES, a widely recognized symmetric-key encryption algorithm, is leveraged to address these security concerns. In this paper, we discuss the integration of AES encryption within the sharding mechanism to ensure the confidentiality and integrity of data exchanged between shards.
