Using Hardware Acceleration to Improve the Security of Wi-Fi Client Devices

摘要

As mobile devices prevail, communications security has become a critical and popular topic in recent years. For example, when a mobile device accesses Wi-Fi, the data communicated with the Wi-Fi access point may be encrypted to provide extra security. However, on a mobile device with limited energy budget, data encryption/ decryption often imposes high pressure on the battery life. In this paper, we review how a recently introduced Extremely Heterogeneous Architecture (EHA) can potentially be used to improve performance and energy efficiency of data encryption/decryption on mobile devices.
