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.
