Digital communication security is critical amid growing privacy threats, particularly on instant messaging platforms vulnerable to eavesdropping. One solution to address this challenge is the use of encryption. This study aims to enhance the security of text messages through the implementation of End-to-End Encryption (E2EE) by combining the Advanced Encryption Standard (AES) 256-bit for symmetric encryption and the Elliptic Curve Diffie-Hellman (ECDH) for secure key exchange. AES was selected for its ability to provide fast and efficient encryption, while ECDH ensures secure key exchange through the mathematical complexity of elliptic curves. The results demonstrate that AES 256-bit achieves an average encryption time of 0.0196 milliseconds for text ranging from 3 to 30 characters, accompanied by an Avalanche Effect of 77%, indicating optimal ciphertext randomness. Meanwhile, ECDH successfully prevented key interception during the exchange process, and the system withstood simulated man-in-the- middle attacks. Thus, the combination of AES and ECDH proves effective as a secure and efficient E2EE solution for instant messaging applications.
