Abstract

A token device that generates and displays one-time passwords and couples to a computer for inputting or receiving data for generating and outputting one-time passwords and performing other functions is provided. The token includes an interface for coupling to a computer. The token may also be coupled to any network that the computer may be connected to, when coupled to the computer. Data and information may be transmitted between the computer and token, and between the network and token, via the computer and interface. The data and information may include one-time password seeding, file transfer, authentication, configuration and programming of the token. The token must be seeded to generate and display one-time passwords. An original, or seed, value is loaded into the token. One-time passwords are subsequently generated or calculated, or both, from the seed value. Seeding of the token involving a counter, time, or time-related functions, may allow synchronization of the token with such functions. The token may support different authentication methods.
