Abstract: This paper presents a Constrained Random Perturbation Vector-based (CRPV) pairwise key establishment scheme and its variant, CRPV+ scheme, for wireless sensor networks (WSNs). Compared to all existing schemes which satisfy only some requirements in a so-called versatileness criteria, the CRPV+ scheme meets all requirements. In particular, the performance improvement of our schemes does not rely on tradeoffs among different requirements, but comes from the use of our constrained random vector strategy.
