We propose a new definition for searchable proxy re-encryption scheme (Re-PEKS), define the first known searchable proxy re-encryption scheme with a designated tester (RedPEKS),and then give concrete constructions of both Re-PEKS and Re-dPEKS schemes that are secure in the random oracle model, along with the proofs.
