Heise.de has described that customers of Intel’s eleven and twelfth technology main processors are unable to participate in UHD Blu-ray discs thanks to the halt of help situated in the SGX instruction set. The reasoning for Intel to prevent allowing for for the playback of the Blu-ray technological know-how on those people two generations is that the method thinks that there is a security vulnerability at hand, triggering the disc to be unable to be examine.
Blu-ray discs are incapable of being viewed on Intel Rocket Lake & Alder Lake-based programs owing to large-protection dangers located by unique programs.
The playback of UHD Blu-ray discs utilizes vastly high demands. 1st, the disc lookups to discover if it meets the compatibility specifications provided by the technique processor. Then, the disc should assure that quite a few electronic legal rights management systems are in put, this sort of as state-of-the-art obtain content material procedure (AACS 2. ) copy security, significant bandwidth digital content material protection (HDCP two.2), and Intel’s SGX technologies.
Breaking down the three technologies protections in additional depth,
- Innovative Access Content material Program, or AACS, is a sort of copy defense for Blu-ray discs issued by the Sophisticated Access Material Program Licensing Administration (AACS LA). AACS enables accessibility for Blu-Ray players with a specific set of encryption keys. If any of people keys turn out to be compromised, AACS can be revised. At the moment, AACS is on version two.2.
- Substantial-bandwidth Electronic Material Defense, or HDCP, is the standard for copy and written content defense established by the tv and film market. HDCP is on HDMI connections for devices, this kind of as Blu-ray players, electronic cable packing containers, and several streaming products.
- Intel SGX is the firm’s in-property hardware-dependent encryption, permitting people to defend their delicate info by positioning it into a highly secured territory inside of the system’s memory. The course of action encrypts memory parts making use of protection recommendations that are indictive to the CPU. The Blu-Ray Association at the moment needs all processors to assistance Intel SGX technologies.
Intel provides SGX assistance for the firm’s sixth-generation main processors up to the tenth-era core chips. On the other hand, the two 11th Gen Core Rocket Lake and the present-day 12th Gen Main Alder Lake processors have never made available assistance for SGX, which is creating several UHD Blu-ray customers to be unable to enjoy their discs on their more recent systems.
Intel has never resolved why they halted support for the SGX technological innovation in the previous to processor family members. It is possible that because of to protection vulnerabilities uncovered when accessing the data on ultra superior definition Blu-ray discs, the process was locating extra fake characteristics, producing superior degrees of incompatibility. Rather of altering the SGX encryption technological know-how, Intel has deleted it on their final two generations of processors. This action has induced computer system people to be not able to enjoy Blu-ray discs on their methods and possibly spend for a standard Blu-ray participant or decide into streaming motion pictures and tv shows on the net.
