JITSI VOIP PASSWORD

Retained Secrets ( RS), or a secret like an additional password Together with these values the peers may also exhange additional secrets, such as Refer to key continuity and key recovery answers for more New Diffie-Helman key-pairs for each session. Secure phase - confirm the cryptographic data and switch to SRTP modeĭuring the first phase both ZRTP peers exchange information about symmetricĬryptographic algorithms, key agreement algorithms, and authentications modes theyĭuring the next phase the peers generate their Diffie-Helman values andĮxchange the public part of the Diffie-Helman key pair.Key agreement phase - exchanging the key material.Discovery phase - detecting if the peers supports ZRTP.In principle ZRTP uses three phases to negotiate and setup the SRTP master keys the ZRTP cache file was copied by a bad guy?.the ZRTP cache file was deleted or is corrupt?.Which SRTP authentication algorithms does GNU ZRTP implementations support?ĭoes ZRTP require SIP, XMPP or other signaling protocols?ĭoes ZRTP store data about me, does it store used keys?Ĭan ZRTP detect and report Man-in-the-Middle attacks? Which key agreement algoritms are available in GNU ZRTP?

Which cryptographic algoritms are available for secure RTP (SRTP) in GNU ZRTP? GNU ZRTP - what is it, where to find, what to expect What happens if the other party’s program does not support ZRTP? RTP, SRTP, and ZRTP - what is their relationship? Not require special infrastructure or registration. Therefore the handling must be simple, easy to use, and shall Usability is of major importance for VoIP peer-to-peerĪpplications: these applications are mainly used by non-IT Technology may have on its implementation, deployment, and While it is important to look at the technology, the protocols andĪlike, it is also important to look at the implications a specific

ZRTP is a protocol that negotiates the keys and other information required to setup a SRTP audio and video session.

To use SRTP in an efficient way VoIP applications should be able to negotiate keys and other parameters in an automatic fashion.

The Secure Real-time Transfer Protocol (SRTP) enhances security for RTP and provides integrity and confidentiality for RTP media connections.

During the last years several activities started to enhance the Therefore most VoIP applications are considered insecure

Internet in clear, thus the data is not protected from eavesdropping Many VoIP applications send RTP data over the public These protocols is the workhorse for VoIPĪpplications. The ever growing use of Voice over IP (VoIP) and other mediaĪpplications triggered a more widespread use of the Real-time Transfer
