OTT service providers encrypt their premium content using Digital Rights Management (DRM). A process of acquiring the decryption keys will therefore take place inside the service platform before viewers can watch the desired content. This process is based on what we call a session token. So, what is it?
Irdeto 2 Decryption Software 16
Under the Digital Video Broadcasting (DVB) standard, conditional access system (CAS) standards are defined in the specification documents for DVB-CA (conditional access), DVB-CSA (the common scrambling algorithm) and DVB-CI (the Common Interface).[1] These standards define a method by which one can obfuscate a digital-television stream, with access provided only to those with valid decryption smart-cards. The DVB specifications for conditional access are available from the standards page on the DVB website.
The decryption cards are read, and sometimes updated with specific access rights, either through a conditional-access module (CAM), a PC card-format card reader meeting DVB-CI standards, or through a built-in ISO/IEC 7816 card reader, such as that in the Sky Digibox.
Due to the common usage of CA in DVB systems, many tools to aid in or even directly circumvent encryption exist. CAM emulators and multiple-format CAMs exist which can either read several card formats or even directly decrypt a compromised encryption scheme. Most multiple format CAMs and all CAMs that directly decrypt a signal are based on reverse engineering of the CA systems. A large proportion of the systems currently in use for DVB encryption have been opened to full decryption at some point, including Nagravision, Conax, Viaccess, Mediaguard (v1) as well as the first version of VideoGuard.
The basic Irdeto 2 works in UNI readers without any problems and can even be shared via Oscam. However, there may be several problems in this basic version of Irdeto 2. For example, the Skylink provider can remotely send an EMM command for a specific decoder card firmware, for a specific user, to change the Surflock function in the card firmware. This feature then disables the decryption of more than 2-3 channels simultaneously (i.e., retrieving ECM requests from the card more than 2-3 times in 10 seconds, which is the lifetime of the Irdeto-2 decryption key). Therefore, it will not be possible to share the card.
It's only a matter of time before the code cracks through the card's firmware. It's just a matter of creating an emulator for a specific decryption system. It's a matter of time to create an algorithm that can handle 100% emulation of any Irdeto card or any CAM module. Everything can be emulated, imitated, replaced, ... etc. . At the same time, the more someone tries to encrypt the data, the bigger the target for crackers.
The problem is the same in Firefox (72.0.1) and Chrome (79.0.3945.130) (with DRM enabled in both). I note that both ITVPlayer and BritBox are getting an error 400 from a call to itvpnp.live.ott.irdeto.com/Widevine/getlicense as the page loads (this returns with a successful 200 response in Windows). This was all working fine in December
Description: The Ericsson RX8310 Distribution Receiver lets operators take full advantage of the efficiency improvements from DVB-S2 modulation, PREKOR by Ericsson dynamic pre-correction, and MPEG-4 AVC compression to distribute three times the amount of content through a satellite transponder verses traditional satellite distribution solutions. The RX8310 combines a DVB-S2 capable demodulator with Director by Ericsson secure content delivery and over-air receiver control solution as a standard feature. For high capacity digital turn-around, the RX8310 provides the option to decrypt multiple services allowing decryption of a complete multiplex of channels with a single unit. Single service decoding options for MPEG-2 and MPEG-4 AVC 4:2:0 SD video, and HD service down-conversion means the RX8310 can provide a simple and cost-effective route to hand-off video into an analog network or for service monitoring.
Novelsat was claiming that satellite broadcasters who use industry-standard BISS/BISS-E-based DRM have suffered hacks, with decryption keys regularly posted to social networks. In response, the company offers NovelSat ProtCASTER which it believes is the only satellite broadcast DRM platform based on virtually unbreakable AES 256-bit encryption.
