END-TO-END NETWORK ENCRYPTION FROM CUSTOMER ON-PREMISE NETWORK TO CUSTOMER VIRTUAL CLOUD NETWORK USING CUSTOMER-MANAGED KEYS

Abstract:

For end-to-end encryption of a virtual cloud network, a VPN tunnel from a customer device is terminated at a host network headend device using encryption keys secured in hardware and managed by the customer. The network headend device can be a card in a bare-metal server with one or more network virtualization devices. The network headend device is configured to receive a first key provisioned by a customer; receive a first data packet sent from a device of the customer; and decrypt the first data packet using the first key to obtain information. A network virtualization device is configured to receive the information from the network headend device; ascertain that the information is to be sent to a virtual machine in a virtual cloud network; ascertain that data in the virtual cloud network is configured to be encrypted; and encrypt the information with a second key to generate a second data packet before routing the second data packet to the virtual machine.
