Note on additional diagnostic characters for Marphysa sanguinea (Montagu, 1813) (Annelida: Eunicida: Eunicidae), a recently introduced species in the Netherlands

Recently specimens of the polychaete Marphysa sanguinea (Montagu, 1813) (Annelida: Eunicida: Eunicidae) were reported as an introduction to the Eastern Scheldt in southwestern Netherlands. In order to confirm the species identity, material was examined with SEM and compared with material from Devon near the type locality in Cornwall, UK. These studies confirmed that this was a new record of M. ...

A Simple Attack on a Recently Introduced Hash-Based Secure User Authentication Scheme

User authentication is an important service in network security. Recently, several user authentication protocols have been proposed. However, a scheme which withstands all known attacks is not yet available. The Lee-Li-Hwang (LLH) authentication scheme [3] was proposed to circumvent the guessing attack in the Peyravian-Zunic (PZ) password scheme [6]. However, Yoon, Ryu, and Yoo (YRY) [9] discov...

A Simple Attack on a Recently Introduced Hash-based Strong-password Authentication Scheme

The user authentication is an important part of network security. Several strong-password authentication protocols have been introduced, but a secure scheme, which probably withstands to several known attacks, is not yet available. Recently, a hash-based strong-password authentication scheme was described in [2], which withstands to the several attacks, including replay, passwordfile compromise...
