ABSTRACT:
A system and method for creating a trusted network capable of facilitating secure transactions via an open network using batch credentials, such as batch PKI certificates, is presented. A certificate is bound to a group, or batch, or devices. This certificate is referenced by an activation authority upon processing a request for service by a device. Information regarding the device batch certificate is maintained in a permanent, or escrow, database. A user identity is bound to a device, as a device key is used to sign a user key created on the device in the presence of the user, and a copy of the device key is later used to decrypt the signed user key upon its transmission and receipt.
