Abstract
An authentication technique employs a security device that communicates with a software token construct installed on a user device via a connector. The technique includes secure provisioning of an authentication seed and safe storage of the seed in encrypted form on the user device. A key for decrypting the seed is stored within the security device, and token codes are generated by physically connecting the security device to the user device and conveying the encrypted seed from the user device to the security device over the connector.
