Abstract

The traditional voice call over Global System for Mobile Communications (GSM) and Public Switched Telephone Network (PSTN) is expensive and does not provide a secure end to end voice transmission. However, the growth in telecommunication industry has offered a new way to transmit voice over public network such as internet in a cheap and more flexible way. Due to insecure nature of the public network, the voice call becomes vulnerable to attacks such as eavesdropping and call hijacking. Accordingly, protection of voice call from illegal listening becomes increasingly important.
To this end, an android-based application (named E2ESeVoice application) to transmit voice in a secure way between the end users is proposed based on modified RC4. The performance of the proposed E2ESeVoice application is evaluated in terms of Mean Opinion Score (MOS) and computation time. The MOS score of E2ESeVoice application is measured with encrypted and unencrypted calls and resulted in values of 4.25 (Good) and 4 (Good) respectively. The result shows that the MOS of both tests is comparable and the encryption has not affect the quality of voice.
