Signcryption is a public key or asymmetric cryptographic method that provides simultaneously both message confidentiality and unforgeability at a lower computational and communica...
A convertible authenticated encryption scheme allows a specified recipient to recover and verify a message simultaneously. Moreover the recipient can prove the dishonesty of the se...
In the setting of identity-based encryption with multiple trusted authorities, TA anonymity formally models the inability of an adversary to distinguish two ciphertexts correspondi...
Signcryption is a new cryptographic primitive which simultaneously provides both confidentiality and authenticity. This paper proposes an improved signcryption scheme and a varia...
