Certificateless Hybrid Signcryption
Signcryption is a cryptographic primitive that fulfills both the functions of digital signature and public key encryption simultaneously, at a cost significantly lower than that required by the traditional signature-then-encryption approach. In this paper, we address a question whether it is possible to construct a hybrid signcryption scheme in the certificateless setting. This question seems t...
متن کاملCertificateless KEM and Hybrid Signcryption Schemes Revisited
Often authentication and confidentiality are required as simultaneous key requirements in many cryptographic applications. The cryptographic primitive called signcryption effectively implements the same and while most of the public key based systems are appropriate for small messages, hybrid encryption (KEM-DEM) provides an efficient and practical way to securely communicate very large messages...
متن کاملCertificateless Aggregate Signcryption Schemes
The concept of an aggregate signcryption scheme was first introduced in 2009 by Selvi S.S.D. et. al. in the identity-based setting. The aggregation process of these schemes reduces the amount of exchanged information and is particularly useful in low-bandwidth communication networks and computationally-restricted environments. In this paper, we define a suitable security model for certificatele...
متن کاملCertificateless Signcryption without Pairing
Certificateless public key cryptography is receiving significant attention because it is a new paradigm that simplifies the traditional PKC and solves the inherent key escrow problem suffered by ID-PKC. Certificateless signcryption is one of the most important security primitives in CL-PKC. However, to the best of our knowledge, all constructions of certificateless signcryption (CLSC) in the li...
متن کاملEfficient Certificateless Signcryption Scheme
In this paper, we propose a certificateless signcryption scheme from Weil pairings and give a practical security model. Compared with existing schemes, the new scheme is more efficient.
