Secure Data Sharing in Mobile Environments

Secure data communication over mobile devices in health networks.

“…The solution enhances existing security protocols by reducing their current complexity and computation cost. It has been designed to meet the following fundamental requirements as defined in [20]:…”

“…For this research, we use softwarebased cryptography solution due to its low deployment cost, high usability and interoperability between mobile devices with different platforms. We assume that the 20 underlying operating system of the mobile device is robust and secures the shared memory used for performing cryptographic operations. …”

“…An approach for secure data sharing among members of a particular group is proposed in [20]. The architecture is designed to meet two key requirements:…”

“…In a group of two members, the write process takes 2.4 seconds and the read process is 3.1 seconds (for the first read). The time increases noticeably with larger data size [20], In the healthcare scenario, with hundreds of messages sent in parallel, current times would further increase causing poor data read-write performance. Currently, the mobile device needs to perform multiple encryption-decryption operations for writing or reading data.…”

“…only mobile data security solution that is designed specifically for data sharing among group members. In order to perform fair comparison, we use Wi-Fi network connection with 2.4Mbps downlink and 153Kbps uplink speed to meet the specifications as published in [20]. Since SDSA performs most cryptography operations on the server instead of the device, it significantly outperforms SSS both in terms of time required to read and write data.…”
