see instruction latency appendix. That means you can multiply without any hacks. But division is still much more expensive than right shift.

1. Don't store your private keys in memory.

This does not affect anything. You can still have timing attacks even if you do not store them in memory.

2. Use address space randomization.

Address space randomization is a useless crap that has nothing to do with timing attacks. It only kinda but not really defends against russian snowniggers using buggy programs to gain access to your computer.
