Abstract
Security of voice communication content in the military's voice communication network will be essential. There is no proposed study on voice data security of military communication networks, but security of voice data will be essential when communicating. This paper is about to an encryption/decryption technique of digital voice data to provide security in case of voice calls in a military communication network. In addition, by using a symmetric key algorithm using AES, a secret key is required, and it has the function of transmitting this key to the receiving end before setting it as a voice call, solving the difficulty of distributing the secret key. This paper proposes a security technique for digital voice data that applies a synchronous stream encryption method that is relatively easy to restore synchronization even in the event of loss of synchronization among stream encryption techniques.
