The client device includes a host core and global memory in a common execution environment and a secure core and restricted memory in a secure execution environment. The secure core generates a license challenge only in the context of the secure execution environment and processes a license challenge response that includes a media content decryption key only in the context of the secure execution environment. The secure core decrypts a protected media asset using the media content decryption key only in the context of the secure execution environment such that the decryption key and decrypted media asset will not be in global memory thereby protecting the media asset from unauthorized access."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Decrypting and decoding media assets through a secure data path","description":"A client device for decrypting and decoding media assets through a secure data path.
