Enabling Comparable Data Access Control for Lightweight Mobile Devices in Clouds

Dijiang Huang (Inventor)

Research output: Patent

Abstract

Mobile devices such as smartphones are being widely used to acquire data about users and their surroundings. Unfortunately, these devices are constrained by their limited capabilities. Cloud computing provides a good solution to data outsourcing and computation offloading for these lightweight devices, but it also raises concerns about secure data storage, secure computation, and fine-grained access control in data sharing. To address these security issues cryptographic methods are used to encrypt data before storing it in the cloud. This method is complex and allows cloud service providers the potential to access data, which complicates security issues. Researchers at Arizona State University have developed a constant-size cipher-text policy, comparative, attribute-based encryption program. This approach assists lightweight mobile devices in storing sensitive data in cloud-based storage. The program offloads the major cryptography computational overhead into the cloud. No data content is exposed within the cloud. Limiting service providers access to data increases data security. The system enables lightweight devices to offload computing tasks to the cloud, which improves the speed and provides the device with greater capabilities. Potential Applications Data storage Apps development Lightweight electronic devices Benefits and Advantages Lower Costs Inexpensive method for storing more data. More Power Increases the power of lightweight computing devices such as smart phones or tablets. Retrofit Works with existing devices and applications.
