Classification: CPC H  G | IPC G  H

Claim 0:
1. A method comprising:
generating, in a secure environment of a tamper resistant device in a client device, initial network credentials for accessing a network, wherein the initial network credentials enable the secure environment of the tamper resistant device to be authenticated by a network solution provider before operational network credentials are provided securely by the network solution provider;
using a cryptographic key that is pre-set in the tamper resistant device to encrypt, in the secure environment of the tamper resistant device, the initial network credentials;
cryptographically signing, in the secure environment of the tamper resistant device, the encrypted initial network credentials; and
outputting the encrypted and signed initial network credentials for delivery to the network solution provider,
wherein:
the tamper resistant device is configured for installation by a client device manufacturer into the client device;
the client device manufacturer is not a manufacturer of the tamper resistant device; and
a shrilling key of the manufacturer of the tamper resistant device is used for cryptographically signing, in the secure environment of the tamper resistant device, the encrypted initial network credentials.
