Implementing robust and up-to-date cryptographic algorithms is essential for securing data, transactions, and communications within blockchain systems. A study titled “Combining Elliptic Curve Cryptography and Blockchain Technology to Secure Data Storage in Cloud Environments” proposes a novel technique that integrates Elliptic Curve Cryptography (ECC) with blockchain technology to enhance data security in cloud environments. The data is first encoded using the Elliptic Curve Integrated Encryption Scheme, then signed using the Elliptic Curve Digital Signature Algorithm, and finally confirmed by the blockchain network before being stored in the cloud. Additionally, the paper “Enhancing Blockchain Security by Developing the SHA256 Algorithm” presents a novel modification approach to enhance the performance of SHA-256 by introducing an extended mechanism for generating a 288-bit message digest, thereby strengthening the hashing process. By integrating these advanced cryptographic techniques, blockchain platforms can significantly bolster the confidentiality, integrity, and authenticity of their operations, ensuring robust security against evolving threats.
