Abstract
There are various ways of social communication including writing (WhatsApp, Messenger, Facebook, Twitter, Skype, etc), calling (mobile phone) and voice recording (record your voice and then send it to the other party), but there are ways to eavesdropping the calls and voice messages, One way to solve this problem is via cryptographic approach. Chaos cryptography build on top of nonlinear dynamics chaotic system has gained some footstep in data security. It provides an alternative to conventional cryptography built on top of mathematical structures. This research focuses on the protection of speech recording by encrypting it with multiple encryption algorithms, including chaotic maps (Logistic Map and Sine Maps).

This paper proposes a new and efficient chaos-based cryptosystem for multiuser speech encryption. In this regards, Chua chaotic systems are added to the transmitters and receiver to generate the chaotic encryption/decryption keys. The User, who has been selected to send the speech information, encrypts voice information by the chaotic keys and sends it to the base station. To encrypt the speech signal, combination of Chaotic Matrix Operation for Randomization or Encryption and XOR operation is s...
