<p>The invention concerns a system and a method for creating a secure network capable of facilitating secure transactions via an open network using batch identity credentials, such as batch public key infrastructure certificates. A certificate is related to a group, or batch, of devices . Said certificate is referenced by an activating authority when a service request from a device is processed. Data concerning the certificate of the batch of devices are kept in a permanent or engagement database. A user identity is related to a device, since a device key is used for signing a user key created on the device in the presence of the user, and a copy of the device key is subsequently used for decrypting the signed user key during its transmission and its reception.</p> |
