Key predistribution
Web1 feb. 2005 · To facilitate the study of novel pairwise key predistribution techniques, this paper develops a general framework for establishing pairwise keys between sensor nodes using bivariate polynomials. This paper then proposes two efficient instantiations of the general framework: a random subset assignment key predistribution scheme, and a … 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 …

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 ...
In symmetric key cryptography, both parties must possess a secret key which they must exchange prior to using any encryption. Distribution of secret keys has been problematic until recently, because it involved face-to-face meeting, use of a trusted courier, or sending the key through an existing encryption channel. The first two are often impractical and always unsafe, while the third depends on the security of a previous key exchange. Websymmetric, pairwise key shared between two sensors, which is the basis of other security services such as encryption and authentication. Several key predistribution techniques have been developed recently to address this problem. Eschenauer and Gligor[6] proposed the basic probabilistic key predistribution, in which each sensor is
