@ -22,9 +22,10 @@ This implementation of Zcash is not resistant to side-channel attacks. You
should assume other unprivileged users running on the same hardware as your
`zcashd` process will be able to:
- Determine which note your are spending by observing cache side-channels as you
perform a JoinSplit operation. This is due to probable side-channel leakage in
the libsnark proving machinery.
- Determine the values of your secret spending keys, as well as which notes you
are spending, by observing cache side-channels as you perform a JoinSplit
operation. This is due to probable side-channel leakage in the libsnark
proving machinery.
- Determine which notes you own by observing cache side-channel information
leakage from the incremental witnesses as they are updated with new notes.
