Abstract

A method for secure processing of encrypted data within a receiver includes receiving a packet of encrypted compressed data and allocating a region of memory for storing a decrypted version of the packet of encrypted compressed data. The allocation is in response to, and after, reception of the encrypted compressed data. A size of the region of the memory allocated is equal to a size of the packet of encrypted compressed data that is received. The method further includes modifying a configuration of an access authorization filter for defining access rights to the allocated region, decrypting the packet of encrypted compressed data, and storing, in the allocated region, the decrypted compressed data of the packet. The aforementioned allocation, modification, decryption, and storage steps are repeated in response to each new reception of a packet of encrypted compressed data so as to dynamically modify the configuration of the access authorization filter.
