Spatial encryption was first proposed by Boneh and Hamburg in 2008. It is one implementation of the generalized identity-based encryption schemes and many systems with a variety of properties can be derived from it. Recently, Hamburg improved the notion by presenting a variant called doubly-spatial encryption. The doubly-spatial encryption is more powerful… CONTINUE READING
