@ -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.
