Which of the following is the GREATEST advantage of elliptic curve encryption over RSA encryption?
A. Computation speed
B. Ability to support digital signatures
C. Simpler key distribution
D. Greater strength for a given key length
Correct Answer: A
Explanation/Reference:
The main advantage of elliptic curve encryption over RSA encryption is its computation speed. This method was first independently suggested by Neal Koblitz and Victor S. Miller. Both encryption methods support digital signatures and are used for public key encryption and distribution. However, a stronger key per se does not necessarily guarantee better performance, but rather the actual algorithm employed.
