My reading is that the primary vector is based on the size of the chunks (due to deterministic chunking and length-preserving encryption). Would padding chunks with random-length data (prior to encryption) help mitigate this at the cost of additional storage (and complexity)?
- cperciva 2y agoTarsnap 1.0.41 (released today) adds padding for exactly this reason.
- ThomasWaldmann 2y agoborg supports the "obfuscate" pseudo compressor since 1.2.0 (since Feb 2022), that adds random extra length to the chunks, using one of 2 different algorithms to determine the extra length.
