Abstract
The present disclosure relates to a system and method for forensic access control of an electronic device. More specifically, the present disclosure relates to a system and a method for handling encryption and decryption of access keys of an electronic device.
Claims17
A method for handling encryption and decryption of access keys of an electronic device, the method comprising:
- creating, by a first organization, a first asymmetric key pair (AKP),
- delivering a private key of the first AKP to a second organization,
- receiving, by a fourth organization, a public key of the first AKP,
- creating, by the fourth organization, a second AKP,
- storing, by the fourth organization, a public key of the second AKP in an electronic device and configuring the electronic device to encrypt at least one access key of the electronic device using the public key of the second AKP,
- encrypting, by the fourth organization, a private key of the second AKP using the public key of the first AKP,
- delivering, by the fourth organization, the encrypted private key of the second AKP to a third organization,
- delivering, by the third organization, the encrypted private key of the second AKP to the second organization,
- decrypting, by the second organization, at least one encrypted access key of the electronic device by:
- decrypting the encrypted private key of the second AKP using a smart card comprising the private key of the first AKP,
- decrypting the at least one encrypted access key of the electronic device using the decrypted private key of the second AKP.

A system for handling encryption and decryption of access keys of an electronic device, the system comprising a first, second, third and fourth organization, each organization having at least one computer,
- wherein the at least one computer of the first organization is arranged to:
- create a first asymmetric key pair (AKP),
- store a private key of the first AKP in a manner suitable for making the private key of the first AKP available to the second organization
- wherein the at least one computer of the fourth organization is arranged to:
- receive the public key of the first AKP,
- create a second AKP,
- store a public key of the second AKP in the electronic device and configure the electronic device to encrypt at least one access key of the electronic device using the public key of the second AKP,
- encrypt a private key of the second AKP using the public key of the first AKP,
- transmit the encrypted private key of the second AKP to the at least one computer of the third organization,
- wherein the at least one computer of the third organization is arranged to:
- receive the encrypted private key of the second AKP from the at least one computer of the fourth organization,
- transmit the encrypted private key of the second AKP to the at least one computer of the second organization,
- wherein the second organization has access to the private key of the first AKP, and to the at least one encrypted access key of the electronic device,
- wherein the at least one computer of the second organization is arranged to:
- receive the encrypted private key of the second AKP from the at least one computer of the third organization,
- decrypt the at least one encrypted access key of the electronic device by:
- decrypting the encrypted private key of the second AKP using a smart card comprising the private key of the first AKP,
- decrypting the at least one encrypted access key of the electronic device using the decrypted private key of the second AKP.
