side channel attack on RSA implementation

Question

What classes of side-channel attacks are applicable to RSA implementation and what is the efficiency rate ?

Answer 1

One type of side channel attacks on RSA is timing attack. It explots the timing variability of operation implementation. To secure against RSA timing attack, constant-time operations are implemented.

Answer 2

As far as I can find out there one of "Paul Carl Kocher" development was Timing Attack, that can break implementations of RSA, a timing attack is a side channel attack that attacker attempts to compromise a cryptosystem by analyzing the time taken to execute cryptographic algorithms.
