QuestionQ8

VerifiedInfrastructure and System Security

You are responsible for security at a defense-contracting firm and are evaluating several potential encryption algorithms. One algorithm under review is not integer-based, uses shorter keys, and is public-key based. What type of algorithm is it?

Explanation

Elliptic-curve cryptography is a public-key approach based on the mathematics of elliptic curves rather than integer factorization. It can provide comparable security with substantially shorter key sizes than RSA.
