End-to-End Pairwise Key Establishment Using Multi-Path in Wireless Sensor Network

Overview Resource aware random key pre-distribution schemes have been proposed to overcome the limitations of energy constrained wireless sensor networks. In most of these schemes, each sensor node is loaded with a key ring. Neighboring nodes are considered to be connected through a secure link if they share a common key. Nodes which are not directly connected establish a secure path which is then used to negotiate a symmetric key. However, since different symmetric keys are used for different links along the secure path, each intermediate node must first decrypt the message received from the upstream node. Notice that during this process, the negotiated key will be revealed to each node along the secure path.

Devil's Advocate: More hazards of buying technology

Politically astute IT managers may be reluctant to follow any other path when faced with powerful interests within their user base. It is easy to get into email and users can be added to the system until everybody is connected to the world at large.

Through the fog... mobile tariffs

And there are different charging schemes for all of these services. When new GPRS data services were rolled out, users had to switch from thinking in terms 'price per minute connected' to 'price per megabyte of data transferred'.

US House of Reps passes anti-spam bill

It permits, but does not require, the Federal Trade Commission to establish a "do not spam" registry, overrides many state laws, and imposes an "opt out" standard instead of a more stringent "opt in" requirement.

Radioactive: Taipei gets meshed up

Because each node relies on those next to it to interoperate, they need to speak the same lingo. Each device will be own its own network router, relaying data to the next node (another 4G) phone. For fixed networks to have any-to-any connectivity...

Peter Cochrane's Blog: More wireless equals more wires

But behind all of this will be an increasingly dense network of fibre and wires to get the base-band signals to each wireless node. The connection of nodes to the spine network will remain the exception for all but a very few cases.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
