A method for generating an encryption key for use in an encryption process at a device, the method comprising: measuring respective values of a plurality of features of the device to generate a plurality of feature values, normalising the feature values using a respective normalisation map for each feature to generate a plurality of normalised values, and generating the encryption key in dependence on the normalised values.

Security credentials

A method for generating an authentication key for providing a digital signature at a device for authenticating an output from a ring comprising a plurality of peers, the method comprising generating respective security credentials for each peer of a plurality of peers constituting a ring of peers, at least one security credential being generated in dependence on one or more feature of the respective peer device; generating a ring key in respect of the ring in dependence on the respective security credential of each peer constituting the ring; and generating an authentication key in dependence on the ring key, a security credential of a first peer and respective security credentials of at least one of the other peers.
