Moving forward with fine-root definitions and research.

In the letter ‘Fine roots – functional definition expanded to crop species?’ Dr Zobel emphasizes the importance of heterogeneity within crop-root systems. We agree.

Enhanced McCullagh-Barreto identity-based key exchange protocols with master key forward security

Master key forward security is an important property for identity-based key exchange protocols. Unfortunately, most of existing identity-based key exchange protocols do not satisfy this property. In this paper, we firstly analyze Xie’s modified protocol to show that signature is undesirable for an identity-based key agreement protocol with the master key forward secrecy. Then we present two imp...
