53 MPH200 series video encoders WebUI user manual
RSA involves a public key and a
private key. The public key can be
known to everyone and is used for
encrypting messages. Messages
encrypted with the public key can only
be decrypted using the private key. The
public key for the RSA algorithm are
generated by MPH key generator and
appears in the “Current RSA Public
Key” box.
Video stream encryption and authentication
MPH200 series supports video stream encryption and authentication, it
adds authentication information to video elementary stream.
It allows verifying the exact encoder has encoded the video stream and
video is authentic. Authentication is done by a hardware chip in the device
called trusted platform module (TPM). TPM is a hardware chip in devices
that securely holds RSA key and generates RSA-signatures by it.
You can have a certication (x509) for TPM RSA key pairs (e.g. signed by
Teleste) mapped to the serial number of the MPH encoder, showing that
particular device encoded the video. So any recording can be traced back
to exact MPH unit.
Enables/disables SRTP feature.
A single “master key” can provide keying material for encryption and
integrity protection for both SRTP and SRTCP streams.
Video stream authentication is based on secure RSA private key stored
safely on Trusted Platform Module (TPM). SRTP uses 2048bit RSA
mode encryption for authentication. RSA delivers a higher level of
security strength compared to other algorithms.
Enables/disables video stream authentication feature.
