A newly filed patent (Publication Number: US20240037217A1) describes a system for digital rights management that includes a platform with at least one processor and memory device. The system involves determining if digital media is locally installed before initiating the operating system. If not installed, a first Unified Extensible Firmware Interface (UEFI) application generates attestation data and communicates with a server to receive the digital media and decryption key. The binary file is sealed using a sealing enclave and a unique local decryption key is generated before installation on the platform's storage. Additional operations include loading and decrypting the sealed binary file in a second UEFI application, with successful decryption leading to the opening or execution of the digital media.
Furthermore, the system involves utilizing encrypted channels, RSA public keys, and symmetric private keys for secure communication and verification processes. It also supports hypervisors for launching virtual machines with segregated resources, generating unique cryptographic keys, and validating virtual machines using these keys. In cases where the digital media is an update recovery script, recovery instructions are retrieved after decrypting the sealed binary file. The patent also covers a method and apparatus for digital rights management, mirroring the system's functionalities and encryption protocols to ensure secure handling of digital media and efficient execution of operations on the platform.
