Using hardware acceleration to improve the security of Wi-Fi client devices

Abstract

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. © Springer-Verlag Berlin Heidelberg 2014.
