Random data

In this section:

Note

Random data is only available for the eSecIP Professional and eSecIP Standard editions.

The randomData information type is optional for the product configuration file.

Random data can be generated by the Security Appliance and provisioned onto the device during a manufacturing run. The random data will differ from one device to another, and from one configuration object to another on the same device. Use this information type for applications that require high entropy to seed a pseudo-random number generator, or perhaps as seed material for cryptographic keys derived on the device, for example.
