Abstract:
We introduce a new cryptographic primitive identity-based anonymous proxy
signcryption which provides anonymity to the proxy sender while also providing a mechanism to the original sender to expose the
identity of the proxy sender in case of misuse. We introduce a formal definition of an identity-based anonymous proxy signcryption
(IBAPS) scheme and give a security model for it. We also construct an IBAPS scheme and prove its security under the discrete logarithm
assumption and computational Diffie–Hellman assumption. Moreover, we do an efficiency comparison with the existing identity-based
signcryption schemes and anonymous signcryption schemes and show that our scheme is much more efficient than those schemes, we also
compare the efficiency of our scheme with the available proxy signcryption schemes and show that our scheme provides anonymity to
the proxy sender at cost less than those of existing proxy signcryption schemes.
