Speech communication in Electronic Warfare (EW) environment should be resistant to interception, masquerade and tolerant to communication channel errors. In this paper, we described an algorithm which provides speech compression, strong encryption, error tolerance and speaker authentication features. This Robust Speech Coder (RSC) is backward compatible with the existing codecs with capability to opt for additional features as and when required. General Terms Speech Compression, Triple DES, Robust Secure Coder (RSC) algorithm, Secure Hash Algorithm SHA-512
