developers can develop related applications based on standardized DRM APIs. In implementationIn the process of DRM, trustzone, an arm-level security technology, can reinforce the security of DRM at the hardware architecture level. So what is trustzone? To put it simply, trustzone is a security technology at the system architecture level. It virtualizes the ent
Since the iphone 5s opened fingerprint recognition function, Android smart machines have followed, the major handset manufacturers even push their security performance. In reality, however, fingerprint technology does not save the safety of mobile phones. It is reported that only one day after the IPhone 5s was released, Chaoscomputerclub, Europe's largest hacker group, announced that it had cracked the touch ID and recorded the operation in video. On the other hand, Andro was spared. Accordin

If large physical addresses are supported, multi-core processors must be supported, and if virtualization is supported, large physical addresses, multicore processors, and TrustZon
keys exposed to host CPU Clear video streams delivered to video decoder * Device implementations may use a trusted bootloader, where in the bootloader is authenticated via an OEM key stored on a system partition.Security level detailsLevel 1 In this implementation Widevine DRM keys and decrypted content are never exposed to the host CPU. only security hardware or a protected security co-processor uses clear key values and the media content is decrypted by the secure hardware.

In the previous chapter, we briefly talked about how the hardware to prepare the chip start-up mode, after the hardware has been prepared to understand the nature of the software is how the process is. Friends who have contacted s5p4412 must know irom boot boot, burning write startup code when there are four files to burn (Bl1,bl2,u-boot.bin, TSZW). In fact,
