Abstract:
The subject matter discloses a method and a system for securely distributing a credential and encryption keys for physical devices. The system comprises a security server and a physical device. the physical device comprises a memory module configured to store a share of the credential, a communication module configured to exchange signals, and a processing module configured to execute calculations upon request received on a wireless manner via the communication module from the security server, the calculations are transmitted to the security server to execute a multi-party computation process. The multi-party computation process outputs two shares of the credential, a first share is stored in the physical device. The physical device does not have access to the credential.

Claim (Index 11):
A method for securely distributing a credential uniquely associated with a physical device, comprising:\n in a manufacturing phase,\n exchanging information between a processing module of the physical device and a security server to cooperatively execute a multi-party computation (MPC) process, wherein the output of the process is two shares of the credential, and \n storing one share of the credential in the physical device and another share of the credential in the security server, wherein the other share of the credential is stored in association with an identifier of the physical device, and wherein the physical device does not have access to the credential; and \n in a usage phase,\n the physical device receiving a request to authenticate versus a third party, and \n the third party exchanging information with both the physical device and the security server to authenticate the physical server versus the third party without any one of the third party, wherein the physical device and the security server have access to the credential.
