In this paper, we present a construction of public key encryption
secure against related key attacks from hash proof systems in the
standard model. We show that the schemes presented by Jia et
al. (Provsec2013) are special cases of our general theory, and also
give other instantiations based on the QR and DCR assumptions. To
fulfill the related key security, we require the hash proof systems
to satisfy the key homomorphism and computational finger-printing properties. Compared with the construction given by Wee (PKC2012), our construction removed the use of one-time
signatures.
