Trusted Computing/Authentication Rutgers – Camden (CS) • Security is the fastest growing sector of the telecommunications market today • Security involves: encryption, authentication, access control, identity management, user provisioning, … • Telecom often involves access to remote resources, requiring authentication of users and monitoring of users’ access privileges July 11, 2003 Commission on Jobs Growth and Economic Development 54
Trusted Computing/Authentication Some Research Themes • Authentication of remote users is usually done by passwords. • Traditional (alphanumeric) passwords are not user-friendly and lead to security problems and increased IT costs. • Graphical passwords: userfriendly; provide an extremely large password space (similar to a cryptographic key space) and thus are inherently more secure. • Human-factors analysis of new password schemes July 11, 2003 Commission on Jobs Growth and Economic Development 55
Trusted Computing/Authentication Impact of Research: • Passwords are the most common method for authentication, but also one of the most vulnerable to cyber as well as physical attack. • Improved authentication will impact human-computer interface, security. • Will allow users to directly use passwords as cryptographic keys • Collaborations: Drexel, Brooklyn Poly. , Minnesota • Collaborations: Unisys • Password research is of great interest to software and telecommunications industries.
