dc.description.abstractID-based cryptosystems (IBCs) allow the use of publicly identifiable information in public encryption keys, which reduces the overhead of certificate management and eliminates the need for a certificate authority in the public-key infrastructure. Up to now, bilinear pairing technology is usually used in ID-based paradigms. However, it is expensive in computation time and is unsuitable for mobile networks. Over recent years, the evolution of mobile devices has seen them transformed from a voice communication device to a daily life information center that is restricted by poor battery capacity and limited computation power. Thus, interest in pairing-free ID-based algorithms among researchers is growing. Herein, a pairing-free IBC consisting of ID-based encryption, digital signatures, and key exchange schemes is presented. All of the schemes use the same public and private key definitions, which makes IBC implementation straightforward. Proof of the correctness and security analysis of the scheme are provided. Furthermore, the performance of the proposed system is compared with well-known pairing-based systems and other well-known pairing-free ones.th
