ABSTRACT
In this paper, we survey the state of research on identity-based cryptography.
We start from reviewing the basic concepts of identity-based encryption and signature schemes,
and subsequently review some important identity-based cryptographic schemes based on
the bilinear pairing, a computational primitive widely used to build up various identity-based
cryptographic schemes in the current literature.
We also survey the cryptographic schemes such as a certificate-based encryption scheme
and a public key encryption scheme with keyword search
, which were able to be constructed
thanks to the successful realization of identity-based encryption.
Finally, we discuss how feasible and under what conditions identity-based cryptography may be
used in current and future environments and propose some interesting open problems concerning
with practical and theoretical aspects of identity-based cryptography.
