This study explores the use of phone and secure messaging via an online patient portal in mediating the communication between patients and their healthcare providers. In analyzing the messages handling processes, we found that although both phone and secure messages were answered in similar manners, the interplay of the frontand back-end roles in collaborative work resulted in patients’ prefere...

A key feature for Internet of Things (IoT) is to control what content available each user. To handle this access management, encryption schemes can be used. Due the diverse usage schemes, there are various realizations 1-to-1, 1-to-n, and n-to-n in literature. This multitude methods with a wide variety properties presents developers challenge selecting optimal method particular use case, which ...

In this paper, we describe a secure group communication protocol for a fault-tolerant synchronous ring. Our protocol, named Secure Synchronous Ring Protocol (SSRP), integrates a secure group communication facility into an existing scalable, fault-tolerant ring protocol. SSRP is a hierarchical group communication protocol that employs Cliques GDH contributory key management protocol and Diffie-H...

The most exciting recent development in nonlinear dynamics is realization that chaos can be useful. One application involves "Secure Communication". Two piecewise linear systems with switching nonlinearities have been taken as chaos generators. In the present work the phenomenon of secure communication with chaos masking has been investigated experimentally. In this investigation chaos which is...
