Abstract
A method and an apparatus to perform Secure Real-time Transport Protocol-on-the-fly (SRTPoF) are disclosed. In one embodiment, the method includes monitoring negotiation between a first Voice-over-Internet-Protocol (VoIP) device and a second VoIP device after a call has been initiated between the first and the second VoIP devices, determining whether the first VoIP device is Secure Real-time Transport Protocol (SRTP)-capable and whether the second VoIP device is SRTP-capable, and performing SRTP-on-the-fly on a Real-time Transport Protocol (RTP) stream transmitted between the first and the second VoIP devices to make the call secure if the first VoIP device is not SRTP-capable and the second VoIP device is SRTP-capable. Other embodiments have been claimed and described.
