Abstract
A technique is utilized in the configuration and seeding of security tokens at third party facilities, particularly at facilities of a configuration agent, such that a token can be configured without the configuration agent having security-defeating knowledge about the token. Such a technique allows a third party to provision a token with a seed, but in such a way that the third party will not know, or be able to construct, the seed after the seed provisioning process is complete. The seed may include, by way of example, a symmetric key or other secret shared by two or more entities. In some arrangements, a method is used for secure seed provisioning. Data is derived from inherent randomness in a token or other authentication device. Based on the data, the token or other authentication device is provisioned with a seed.
