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

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.

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.

    $\begingroup$ Actually, Paul's work was far more focused on various power side channel attacks (for one, those give far more information to the attacker than a simple timing measurement). $\endgroup$
