IPv6 Usage With Various Operating Systems 2007-09-01 Dell

In a nutshell, IPv6 (Internet Protocol version 6) is the successor to the most common Internet Protocol today (IPv4). This is largely driven by the fact that IPv4's 32-bit address is quickly being consumed by the ever-expanding sites and products on the internet. IPv6's 128-bit address space should not have this problem for the foreseeable future. Additionally, the industry expects the US Federal government to start requiring IPsec (IP security) as part of the IPv6 requirements after June 30th 2008 in their RFQs for most products.

Route Fragility: A Novel Metric for Route Selection in Mobile Ad Hoc Networks 0000-00-00 Rensselaer Polytechnic Institute

A key factor deciding the performance of a routing protocol in mobile ad hoc networks is the manner in which it adapts to route changes caused by mobility. Exploiting the intuition that a less dynamic route lasts longer, this paper proposes a new metric, the Route Fragility Coefficient (RFC), to compare routes. RFC estimates the rate at which a given route expands or contracts. Expansion refers to adjacent nodes moving apart, while contraction refers to their moving closer. RFC combines the individual link contraction or expansion behavior to present a unified picture of the route dynamics. The paper demonstrates that lower the value of RFC, more static (less fragile) the route.

Self-Configurable Key Pre-Distribution in Mobile Ad Hoc Networks 0000-00-00 University of California

This paper presents two new schemes that, in the absence of a centralized support, allow a pair of nodes of a mobile ad hoc network to compute a shared key without communicating. Such a service is important to secure routing protocols. The schemes are built using the well-known technique of threshold secret sharing and are secure against a collusion of up to a certain number of nodes. The paper evaluates and compares the performance of both the schemes in terms of the node admission and pairwise key establishment costs.

Cisco IPICS Enhances Safety and Security at Cisco 2007-08-01 Cisco Systems

Cisco campus in San Jose reaches up to 20,000 people per day. They wanted to manage on-premise emergency response and day-to-day safety and security operations as well as enable location-independent dispatch and collaboration across security operations centers. The challenge was to reduce costs of maintaining dedicated leased lines to Cisco sites for radio communications. Cisco campus deployed Cisco Internet Protocol Interoperability and Collaboration System (IPICS) solutions. This resulted in more rapid response to emergencies, reduced costs of maintaining radio infrastructure and there was better situational awareness from responders, management, and key executives during crisis situations.

Live Webcast: The High Business Risks of Low-Cost Web Hosting 2007-01-24 15:33:32 Verio

Building a successful e-commerce site is a challenge in small and medium-sized businesses (SMBs) that lack infrastructure resources and IT personnel. That's why many SMBs are turning to managed hosting services when it comes to developing their online sales channels.

Join this live TechRepublic Webcast, featuring Dennis Boyle, COO of Verio, as he explores:

How managed hosting can help you build a more lucrative e-commerce Web site

The risks associated with Web hosting�and how to mitigate them

Why going beyond price is critical to selecting the right hosting partner

Key criteria for choosing a Web hosting service

Questions to ask prospective vendors

Hosted by James Hilliard, Moderator for TechRepublic, and featuring live Q&A, this Webcast is your opportunity to learn how you can leverage managed hosting to improve your e-business results. Pre-register today!

COCOON: An Alternative Approach to End-Point Congestion Management 2006-12-13 01:00:24 Alcatel-Lucent

This paper proposes an alternate endpoint congestion management scheme, called COordinated COngestion cONtrol (COCOON). The basic idea is to identify and group connections that may traverse the same backbone link, to enable them to share congestion information, and to coordinate among them all the congestion avoidance/control activities. The size of a COCOON group can be dynamically adjusted so as to magnify the benefits of end-host congestion management. COCOON also allows a new connection to commerce with a congestion window that is large enough to catch up with other connections while not inducing congestion. Finally, COCOON takes into account non-responsive UDP connections and "Bundles" them into a virtual connection that is subject to TCP-like congestion control.

Authenticity by Typing for Security Protocols 2006-12-09 01:00:18 Microsoft

This paper proposes a new method to check authenticity properties of cryptographic protocols. First, code up the protocol in the spi-calculus of Abadi and Gordon. Second, specify authenticity properties by annotating the code with correspondence assertions in the style of Woo and Lam. Third, figure out types for the keys, nonces, and messages of the protocol. Fourth, check that the spi-calculus code is well-typed according to a novel type and effect system presented in this paper. The main theorem guarantees that any well-typed protocol is robustly safe, that is, its correspondence assertions are true in the presence of any opponent expressible in spi.

Types and Effects for Asymmetric Cryptographic Protocols 2006-12-09 01:00:18 Microsoft

This paper presents the first type and effect system for proving authenticity properties of security protocols based on asymmetric cryptography. The most significant new features of the type system are - a separation of public types (for data possibly sent to the opponent) from tainted types (for data possibly received from the opponent) via a subtype relation; trust effects, to guarantee that tainted data does not, in fact, originate from the opponent; and challenge/ response types to support a variety of idioms used to guarantee message freshness. The paper illustrates the applicability of the system via protocol examples.

Timed Spi-Calculus With Types for Secrecy and Authenticity 2006-12-07 01:00:20 Alcatel-Lucent

This paper presents a discretely timed spi-calculus. A primitive for key compromise allows to model key compromise attacks, thus going beyond the standard Dolev-Yao attacker model. A primitive for reading a global clock allows the authors to express protocols based on timestamps, which are common in practice. The authors accompany the timed spi-calculus with a type system, prove that well-typed protocols are robustly safe for secrecy and authenticity and present examples of well-typed protocols as well as an example where failure to typecheck reveals a (well-known) flaw.

Methods That Are Available for Authenticating Internet Protocol Security Sessions 2006-10-13 01:00:15 Microsoft

This webcast describes the various methods that are available for authenticating Internet Protocol security (IPsec) sessions. It presents information about the different authentication methods. The webcast then focuses on deployment considerations and interoperability issues. The deployment considerations may include security, ease of use, distribution, and other factors.
