Patent ID: 7920701

Claim:
A digital content system with improved digital content protection, comprising: a central processing unit (CPU) executing associated software configured to receive an encrypted version of digital content from a source of digital content and in response perform decryption to generate and securely transmit clear text digital data corresponding to said digital content; a bridge coupled to said CPU by a secure data path, said bridge securely receiving from the CPU said clear text digital data corresponding to said digital content; a memory coupled to said bridge by a first insecure data path; a graphics processing unit (GPU) coupled to said bridge by a second insecure data path; and a security engine disposed in said bridge, said security engine providing cryptographic services such that said clear text digital data is encrypted by said security engine and transferred via said bridge over said first insecure data path and said second insecure data path as cipher text to protect said digital content, wherein digital content is transmitted and stored as cipher text in portions of said digital content system susceptible to hacking of insecure data paths so that transmission and storage of said digital content within the digital content system is secure; and wherein said security engine identifies a current context within an index of contexts, where the current context has a corresponding key used to implement a specified cryptographic service.
