The overwhelming acceptance and growing need for Internet of Things (IoT) products in
each aspect of everyday living is creating a promising prospect for the involvement of …

With the dramatically increasing deployment of IoT devices, storing and protecting the large
volume of IoT data has become a significant issue. Traditional cloud-based IoT structures …

With the ever-increasing requirements of delay-sensitive and mission-critical applications, it
becomes a popular research trend to incorporate edge computing in the Internet of Things …

We propose a mediated certificateless encryption scheme without pairing operations for
securely sharing sensitive information in public clouds. Mediated certificateless public key …

Certificateless Public Key Cryptography (CL-PKC) enjoys a number of features of Identity-
Based Cryptography (IBC) while without having the problem of key escrow. However, it does …

In this paper, we introduce a new fine-grained two-factor authentication (2FA) access control
system for web-based cloud computing services. Specifically, in our proposed 2FA access …

Attribute-based encryption has the potential to be deployed in a cloud computing
environment to provide scalable and fine-grained data sharing. However, user revocation …

In this paper, we propose a two-factor data security protection mechanism with factor
revocability for cloud storage system. Our system allows a sender to send an encrypted …

The ever-growing popularity of cloud systems is prompting a revolutionary change in
information technology field. Parallel and flexible services offered by cloud technology are …

We present a study of security in certificateless signatures. We divide potential adversaries
according to their attack power, and for the first time, three new kinds of adversaries are …
