The Evolution of Strong Authentication: Towards a Future of Ubiquitous, Secure Digital Identities
Strong authentication technologies have long been used for providing an extra layer of assurance that an individual accessing computing resources is who they say they are. However, the cost of deploying and managing such systems, including the provisioning of hardware tokens and the strain on helpdesk resources dealing with lost tokens or forgotten passwords, has made their use expensive and complex. New authentication models, however, are changing all that. Key developments include next-generation authentication servers that automate all tasks involved, and services provided in the cloud.
