Selecting Cryptographic Key Sizes

In this article we offer guidelines for the determination of key sizes for symmetric cryptosystems, RSA, and discrete logarithm based cryptosystems both over finite fields and over groups of elliptic curves over prime fields. Our recommendations are based on a set of explicitly formulated hypotheses, combined with existing data points about the cryptosystems.
