N2 - Abdalla et al.[1, 6] proposed a transform of an anonymous IBE (A-IBE) scheme to a PEKS (Public key encryption with keyword search) scheme. Boneh et al. proposed a transform of a PEKS scheme to an A-IBE scheme for only one-bit message. A transform for constructing an A-IBE scheme for polynomially many-bit message by using a PEKS scheme has not been proposed yet. To construct a transform from any PEKS scheme to an A-IBE scheme for a polynomially many-bit message, we firstly define a multiple PEKS (mPEKS) scheme and show that a mPEKS scheme can be constructed from a PEKS scheme. We also prove that if a PEKS scheme is confidential, so is the resulting mPEKS scheme. We then provide a transform from a mPEKS scheme to an A-IBE scheme for a polynomially many-bit message.
