摘要：
The invention relates to a chip for processing a content, comprising at least a microprocessor. Said chip includes an integrated non-volatile programmable memory for storing protection data and protected data, said protection data being intended to be used for authorizing/denying access to said protected data by said microprocessor under execution of a program. The invention allows to protect program and data dedicated to a chip-integrated conditional-access system and to protect features as external connections and downloaded data directly on the chip.
