METHODS CIRCUITS DEVICES AND SYSTEMS FOR PROVISIONING OF CRYPTOGRAPHIC DATA TO ONE OR MORE ELECTRONIC DEVICES
First Claim
1. An electronic device comprising:
- a cryptographic material provisioning (CMP) module adapted to process a provisioning message with a first message portion which is encrypted with a native key of said device and includes first cryptographic material along with a first permissions data vector,wherein said CPM is further adapted to process data bits of a second portion of the provisioning message using the first cryptographic material and in accordance with usage limitations defined in the first permissions data vector.

Abstract
Disclosed are methods, circuit, devices and systems for provisioning cryptographic material to a target device. According to embodiments, a cryptographic material provisioning (CMP) module may be adapted to process a provisioning message with a first message portion which is encrypted with a native key of the target device and which includes first cryptographic material along with a first permissions data vector, wherein the CMP may be further adapted to process data bits of a second portion of the provisioning message using the first cryptographic material and in accordance with usage limitations defined in the first permissions data vector.
