Simulcrypt (SimulCrypt)

A DVB protocol published by ETSI used in IPTV / broadcast TV head-ends to enable use of multiple key management systems. The standardised SCS (Simulcrypt Synchroniser) to ECMG (Entitlement Control Message Generator) interface is used to allow multiple key management systems to operate in parallel, each generating its own (typically proprietary) ECMs (Entitlement Control Messages).

Example traffic

XXX - Add example decoded traffic for this protocol here (as plain text or Wireshark screenshot).

Wireshark

The SIMULCRYPT dissector is fully functional for the SCS - ECMG interface. It decodes the Simulcrypt syntax to analyse different Simulcrypt messages and associated TLV parameters.

Preference Settings

(XXX add links to preference settings affecting how PROTO is dissected).

Capture Filter

You cannot directly filter PROTO protocols while capturing. However, if you know the TCP port used (see above), you can filter on that one.
