Abstract
Methods and systems for processing video data are disclosed herein and may comprise receiving within a single mobile multimedia processor chip integrated within a mobile device, a secure key from an off-chip device integrated within the mobile device. The secure key may be decrypted within the single mobile multimedia processor chip, utilizing an on-chip key. The decrypted secure key may be stored within the single mobile multimedia processor chip. The received encrypted data may be decrypted within the single mobile multimedia processor chip, using the stored, decrypted secure key. The on-chip key may be stored within a one-time programmable (OTP) memory in the single mobile multimedia processor chip. The stored on-chip key may be retrieved from the OTP memory for the decrypting. The stored decrypted received secure key may be encrypted utilizing the on-chip key stored within the single mobile multimedia processor chip.
