ABSTRACT: This study focused on enhancing the Elliptic Curve Digital Signature Algorithm (ECDSA) to improve the security of digitally signed emails. Despite its benefits, ECDSA faced vulnerabilities with its key generation and signature generation phases such as weak elliptic parameters, susceptibility to private key leakage, and insecure hash functions. The study proposed a three-pronged strategy: Firstly, it recommended strengthening elliptic curve parameters using Elliptic Curve NIST P-256 / SEC256RI to combat brute force attacks. Secondly, it suggested replacing the random number generation for the k value with a deterministic nonce mechanism to mitigate private key leakage risks. This adjustment aimed to enhance the security framework of ECDSA, preventing unauthorized access. Thirdly, the study advocated implementing SHA-256 for hash functions to resist collision attacks, crucial for maintaining the integrity of digitally signed documents. Conducted in a simulated Python environment, the research demonstrated a robust approach to overcoming ECDSA’s weaknesses. By enhancing security measures, the study established a more reliable framework for protecting email communication.
