Side channel attack on a partially encrypted MPEG-G file

Abstract: New genome sequencing technologies have decreased the cost of generating genomic data, thus increasing storage needs. The International Organization for Standardization (ISO) working group MPEG has developed a standard for genomic data compression with encryption features. The approach taken in standard MPEG-G (ISO/IEC 23092) to compress genomic information was to group similar data into streams. Taking this into account, one of the protection options considered was to encrypt each stream separately. In this p… Show more

“…21. M43545 Side-channel attack on MPEG-G in Descriptor Stream Contiguous mode [116] This document proves that there is a way to attack and recover data from an MPEG-G file if it is stored in DSC mode. The attack proves that if the pos descriptor is not encrypted, then the position of the SNPs can be inferred.…”

“…In this chapter, we also prove the deficiencies of the initial encryption proposal: in case the encryption is done per stream, using the properties of MPEG-G's encoding permits to deduce the content of a theoretically encrypted stream on the basis of the contents of other unencrypted ones. A paper on this attack has been submitted [69].…”
