Design of Mobile-PKI for using mobile phones in various applications

Abstract

Today's era witnesses the increasing demand of mobile phones and its applications. In Mobile PKI, it is difficult to apply the WAP (Wireless Application Protocol) in mobile environment since wireless internet has lower transmission bandwidth and mobile phone has fundamental limitations like small screen size, low computing power, low memory capacity, etc. To eradicate these problems, development of Mobile-PKI is needed. This paper presents a Mobile Home Agent based Mobile-PKI supporting mobile phones to provide similar security level as the wired PKI. A Mobile Home Agent and Registration Authority have been considered to minimize the work load of mobile phone and CA (Certificate Authority) respectively. Discussion regarding how the proposed Mobile-PKI provides similar security level as the wired PKI and comparisons with existing schemes have been provided.
