International Journal of Computer Research, Special Issue on Advances in Ad Hoc Network Security, 4th Quarter. (Submission Due 1 January 2007) Guest Editor: Nikos Komninos (Athens Information Technology) http://www.ait.gr/special_issue Ad hoc networks are becoming an integral part of the computing landscape. However, these networks introduce new security challenges due to their dynamic topology, severe resource constraints, and absence of a trusted infrastructure. This International Journal of Computer Research (IJCR) special issue seeks submissions from academia and industry presenting novel research on all aspects of security for ad hoc networks, as well as experimental studies of fielded systems. Topics of interest include, but are not limited to, the following as they relate to mobile ad hoc networks: . Key management . Intrusion detection and tolerance . Secure location services . Secure clock distribution . Privacy and anonymity . Performance and security tradeoffs . Secure roaming across administrative domains . Denial of service . Prevention of traffic analysis . Trust establishment, negotiation, and management . Secure routing . Secure MAC protocols . Cryptographic Protocols . Authentication and access control Submission Instructions: Authors should follow the IJCR manuscript format described in the Submissions and Author Information section on the IJCP website Submitted papers must not substantially overlap with papers that have been published or that are simultaneously submitted to a journal or a conference with proceedings. Papers must be submitted in PDF format to the guest editor at nkom(at)ait(dot)edu(dot)gr, and must be received by the deadline of January 1, 2007. Authors should note that the special issue of IJCR paper must have enough value-added for the reader and for archival purposes beyond the published record already available in the conference literature. Minor enhancements to conference papers and papers under review for other publications will not be accepted. Outstanding papers will be invited for possible publication in a book by Nova Science Publishers, Inc. For more information, please see: http://www.ait.gr/special_issue
