MIKEY

The Multimedia Internet Keying (short: MIKEY ) is a standardized according to RFC 3830 Key Exchange protocol. It is characterized by its independence from the underlying signaling protocol, a variety of options for key exchange and low latency from.

MIKEY is mainly used for real-time multimedia application in conjunction with SRTP and typically uses three key exchange process:

• Pre-shared key ( PSK ) method, in which the key must be agreed prior to the transfer of all communication partners. In many communication partners difficult scalable.
• Public key: Asymmetric encryption algorithm, in which coded with the help of public and private key messages and decoded.
• Diffie -Hellman: This principle differs from the above in that no common key has to be transmitted, but can be calculated by two communication parties. This has the advantage that the communication can be conducted over insecure channels. However, the method fails to have more than two communication partners.
