Identity based signcryption schemes without random oracles
Abstract
Signcryption is a cryptographic primitive which performs encryption and signature in a single logical step with the cost lower than signature-then-encryption approach.. In this paper we gave attacks on confidentiality and unforgeability of two identity based signcryption schemes without random oracles. Further we proposed an improved identity based signcryption scheme without random oracles. We also proposed an identity based public verifiable signcryption scheme with third party verification without random oracles.
