Mobile cloud computing (MCC) is embracing rapid development these days and able to provide data outsourcing and sharing services for cloud users with pervasively smart mobile devices. Although these services bring various conveniences, many security ...

In a 5G network-sliced environment, mobility management introduces a new form of handover called inter-slice handover among network slices. Users can change their slices as their preferences or requirements vary over time. However, existing handover-...

Cloud-based Internet of Things, which is considered as a promising paradigm these days, can provide various applications for our society. However, as massive sensitive and private data in IoT devices are collected and outsourced to cloud for data storage, ...

With the increase in network transmission rates, the Internet of Things (IoT) has gradually become a trend. Users can upload the data generated by the device to the cloud database to save local storage space, thereby reducing local storage costs. Because ...

Recently, cloud-based mobile crowdsensing (MCS) has developed into a promising paradigm which can provide convenient data sensing, collection, storage, and sharing services for resource-constrained terminates. Nevertheless, it also inflicts many security ...

With the widespread usage of Android smartphones in our daily lives, the Android platform has become an attractive target for malware authors. There is an urgent need for developing an automatic malware detection approach to prevent the spread of malware. ...

With the rapid growth of the Internet of Things (IoT) devices, security risks have also arisen. The preidentification of IoT devices connected to the network can help administrators to set corresponding security policies according to the functionality and ...

5G heterogeneous network (HetNet) is a novel network topology that integrates various kinds of wireless access technologies such as 4G Long-Term Evolution (LTE), Wi-Fi, and so on. Despite greatly improving spectrum efficiency, it poses enormous challenges ...

Structured Encryption (STE), which allows a server to provide secure search services on encrypted data structures, has been widely investigated in recent years. To meet expressive search requirements in practical applications, a large number of STE ...

The guarantee of social stability comes from many aspects of life, and image information security as one of them is being subjected to various malicious attacks. As a means of information attack, image splicing forgery refers to copying some areas of an ...

The characteristics of social networks has always been a hot topic of scientific research. In order to protect the privacy of users, the owner of the private data need to provide privacy protection when providing inquiries or publishing data. ...

E-healthcare cloud remarkably facilitates patients to outsource their electronic health record (EHR) to achieve large-scale information sharing in real-time for improving the efficiency of diagnosis and treatment. Unfortunately, compared with other ...

In CCS 2019, the privacy-preserving deep package inspection (PrivDPI) was proposed to detect anomalies and suspicious activities in encrypted network traffic, which is a provably secure and highly efficient approach for the end-to-end communication ...

Nowadays, the use of GPS has penetrated everyone's daily life, so the safety of GPS signals has threatened all of us. Since the portable GPS spoof was proposed at the Black Hat Conference, the cost and threshold of GPS spoofing have also been getting ...

The authors analyse the security threats caused by personal wireless local area network (WLAN) sharing, propose schemes under two different conditions, and evaluate the performance of their schemes. WLAN is a widely used low‐cost wireless networking ...

Crypto ransomware encrypts user files and then extorts a ransom for decryption, thus it brings a big threat to users. To address this problem, we propose RansomSpector, an introspection-based approach to detect crypto ransomware. ...

To achieve more powerful task processing capabilities, the smart embedded systems (SES) are interconnected via wireless network to form a collaboration system. However, due to the limitations on system hardware, the SES device are usually built ...

Nowadays, spatial search services bring unprecedented convenience in people’s daily life (e.g., location-based services, social networking) and are becoming more and more popular. To protect the privacy of outsourcing data, several schemes have ...

With the increasing popularity of geo-positioning technologies and mobile Internet, spatial keyword data services have attracted growing interest from both the industrial and academic communities in recent years. Meanwhile, a massive amount of data is ...

Dynamic spectrum access (DSA) is a promising platform to solve the problem of spectrum shortage for which the most challenging issue is spectrum allocation under uncertain availability information, which is referred as a nondeterministic spectrum ...
