Analyst(s): Andrew Phillips, Vic Wheatman


Public key infrastructure has emerged as a preferred solution to enhance application security. It is motivated in part by application "Webification," the growth of application service providers and the extension of internal applications for e-business. Smart cards enable this security to "roam" with the user, rather than limiting users' access via a single piece of hardware.
