System, device, and method of provisioning cryptographic data to electronic devices

A system for cryptographic material provisioning (CMP), the system comprising:

• a first provisioning server to generate a delegation message,
• wherein the delegation message indicates provisioning rights that are delegated by the first provisioning server to a second provisioning server with regard to subsequent provisioning of cryptographic assets to an electronic device,
• wherein the first provisioning server is to generate the delegation message by performing at least one of:
• (A) inserting into the delegation message an association key unknown to the first provisioning server, encrypted using a public key of said electronic device, wherein said public key of said electronic device is usable to encrypt data for subsequent decrypting by said electronic device using said private encryption key of said electronic device;
• (B) inserting into the delegation message a public key of the second provisioning server;
• enabling the electronic device to locally generate said association key unknown to the first provisioning server;
• wherein the association key is retrievable by the second provisioning server based on the public key of the second provisioning server;
• wherein the first provisioning server is to cause delivery of the delegation message from the first provisioning server to the electronic device;
• wherein the second provisioning server is to provision, and based on said delegation message, one or more cryptographic assets to the electronic device, using said association key.
