Device Firmware Reversing to Obtain the Screen Mirroring Protocol
Extend your device compatibility list and provide advanced features – having exact device functioning description!
The client’s product supports a well-known popular mobile device platform, and in particular its functionality of video mirroring from the device screen to an external screen. Basically, this feature works only with the platform-compatible devices.
The client needed this feature to work with devices operating on other platforms. To perform screen/video mirroring, devices establish secure connection with public/private key exchange. Apriorit researchers' task was to reverse the original platform firmware and reconstruct the process of handshaking. This would allow to implement the same process on the accepting side under another platform.
