in this paper that effectively combines the functionalities of digital
signature and encryption and decreases the computational costs and communication
overheads in comparison with the traditional signature-then-encryption
schemes. It simultaneously provides the attributes of message confidentiality,
authentication, integrity, unforgeability, non-repudiation, public verifiability
and forward secrecy of message confidentiality. Since it is based on elliptic
curves and can use any fast and secure symmetric algorithm for encrypting
messages, it has great advantages to be used for security establishment
in store-and-forward applications and when dealing with resource-constrained
devices.]]>Antipa, A., D. Brown, A. Menezes, R. Struik and S. Vanstone,20032003pp: 211223Bao, F. and R.H. Deng,19981998pp: 5559Elkeelany, O., M.M. Matalgah, K.P. Sheikh, M. Thaker, G. Chaudhry, D.
