1. An efficient certificateless signcryption scheme in the standard model

P. Rastegari; M. Berenjkoub

Volume 9, Issue 1 , Winter and Spring 2017, , Pages 3-16


  Certificateless public key cryptography (CL-PKC) is a useful method in order to solve the problems of traditional public key infrastructure (i.e., large amount of computation, storage and communication costs for managing certificates) and ID-based public key cryptography (i.e., key escrow problem), simultaneously. ...  Read More

Volume 7, Issue 2 , Summer and Autumn 2015, , Pages 91-99


  A multi-secret sharing scheme (MSS) allows a dealer to share multiple secrets among a set of participants. in such a way a multi-secret sharing scheme (MSS) allows a dealer to share multiple secrets among a set of participants, such that any authorized subset of participants can reconstruct the secrets. ...  Read More

3. A traceable optimistic fair exchange protocol in the standard model

R. Ganjavi; M. Rajabzadeh Asaar; M. Salmasizadeh

Volume 7, Issue 1 , Winter and Spring 2015, , Pages 3-14


  An Optimistic Fair Exchange (OFE) protocol is a good way for two parties to exchange their digital items in a fair way such that at the end of the protocol execution, both of them receive their items or none of them receive anything. In an OFE protocol there is a semi-trusted third party, named arbitrator, ...  Read More
