A Note on Practical Key Derivation Functions
Shoichi Hirose · IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences · 2011
In this article, we first review key derivation functions specified in NIST SP 800-108 and one proposed by Krawczyk. Then, we propose parallelizable key derivation functions obtained by modifying or using the existing schemes. We also define two measures of efficiency of key derivation functions, and evaluate their performance in terms of the two measures.
