Abstract: Data leakage is a frequent occurrence due to security system vulnerabilities. The key is the most valuable object in the encryption and decryption process. The Hill Cipher algorithm also has a key in the form of several decimal numbers placed in a square matrix. This key exchange will result in system security vulnerabilities. This study uses the Diffie-Hellman technique in key exchange where the key sent by the sender to the recipient is in the form of a number which is the component that forms the actual key value. The results of the study stated that the key generation using the Diffie-Hellman algorithm was successfully used by the Hill Cipher algorithm even though in the generation process it produced several values that did not have the appropriate determinant
Keywords: Hill Cipher, Diffie-Hellman, End-to-end, Encryption, Decryption
