    摘要: Systems and methods for securely executing digital rights management software comprising content code are described. One method comprises receiving encrypted multimedia content and content code from a storage medium by a host processor, wherein the content code provides restricted content distribution by examining an environment in which a player application resides. Based on functions defined within the content code, the host processor partitions the content code into portions. Based on whether the functions corresponding to the portions are related to computations involving confidential data, commands and parameters related to the portions of the content code are generated and forwarded to a secure processor for decrypting the encrypted multimedia content.
