• Spatial encryption is one of the generalized identity based encryption proposed by Boneh and Hamburg in 2008. Spatial encryption provides a framework for generating many identity based cryptosystems such as broadcast encryption, forward secure encryption or ring signature. While this may appear to be an attractive feature, all existing spatial encryption schemes are only selectively secure. In this paper, we present a fully secure spatial encryption scheme based on the three composite order bilinear groups.
