Many certificateless schemes have been proposed for different purposes, but as for as their applications in any electronic cash schemes there is still a lot of potential for strengthening the security aspect, and this paper is an attempt towards this. In this paper we propose a new type certificateless scheme which is applied for group oriented signcryption rather than a signature without using...

Internet of Vehicles (IoV) is a specialized breed Vehicular Ad-hoc Networks (VANETs) in which each entity the system can be connected to internet. In provision potentially vital services, IoV transmits large amount confidential data through networks, posing various security and privacy concerns. Moreover, possibility cyber-attacks comparatively higher when transmission takes place more frequent...

The application of digital signature technology to the Internet vehicles (IoV) is affected by its network and communication environment. In 5G era, influx a large number intelligent devices into mobile requires low transmission delay power consumption as well high-security requirements. To best our knowledge, well-designed solution in which signcryption used has not been proposed IoV research a...

Recently, Liu et al. proposed the first certificateless signcryption scheme without random oracles and proved it was semantically secure in the standard model. However, Selvi et al. launched a fatal attack to its confidentiality by replacing users’ public keys, thus pointed out this scheme actually doesn’t reach the semantic security as claimed. In this paper, we come up with a rescue scheme ba...

A new attack against a novel certificateless aggregate signature scheme with constant pairing computations is presented. To enhance security, a new certificateless signature scheme is proposed first. Then a new certificateless aggregate signature scheme with constant pairing computations based on the new certificateless signature scheme is presented. Security analysis shows that the proposed ce...

According to actual needs, generalized signcryption scheme can flexibly work as an encryption scheme, a signature scheme or a signcryption scheme. In this paper, firstly, we give a security model for identity based generalized signcryption which is more complete than existing model. Secondly, we propose an identity based generalized signcryption scheme. Thirdly, we give the security proof of th...

The rapid development of wireless sensors has accelerated the popularity body area network (WBAN). WBAN use multiple to collect patient’s data, and data is transferred medical cloud for processing analyzing. In order protect in cloud, some heterogeneous signcryption schemes that support equality test have been proposed. However, we observe these same cryptographic parameters different systems. ...
