Key predistribution

WebWe propose a new grid-group deployment scheme in wireless sensor networks. We use combinatorial designs for key predistribution in sensor nodes. The deployment region is divided into square regions. The predistribution scheme has the advantage that all ...

Random key predistribution schemes for sensor networks

WebRecall that in random key predistribution, a key pool is first selected from the universe of possible keys. Each sensor node is then preloaded with a set of keys from the key pool … WebDuring the key predistribution phase, key information is assigned to each node, such that after deployment, neighboring sensor nodes can find a secret key between them.

http://xwxt.sict.ac.cn/CN/Y2013/V34/I9 Web2.2 A Polynomial-Based Key Predistribution Scheme In the context of sensor networks, we briefly review the polynomial-based key predistribution scheme proposed by Blundo et al. [8], which is the basis of our RPB scheme. To predistribute pairwise keys, the authority randomly picks a t-degree symmetric, bivariate polynomial f(x,y)= X 0≤i,j≤t ... Webthe so-called key predistribution. Afterwards, the trusted authority plays no further role in key establishment, so two nodes who require a common key must derive one from their predistributed keys. A well thought-out scheme to allocate keys is thus crucial; we call such a strategy a key predistribution scheme (KPS). on bluetooth in windows
