A Computationally-Efficient Construction for the Matrix-Based Key Distribution in Sensor Network
Source: Cornell University
This paper introduces a variant for the symmetric matrix-based key distribution in sensor network introduced by Du et al. The authors' slight modification shows that the usage of specific structures for the public matrix instead of fully random matrix with elements in Zq can reduce the computation overhead for generating the public key information and the key itself. An intensive analysis followed by modified scheme demonstrates the value of their contribution in relation with the current work and shows the equivalence of the security.
