METHOD FOR SECURING THE RENDEZVOUS CONNECTION IN A CLOUD SERVICE USING ROUTING TOKENS

Abstract:

Systems and methods for establishing a secure connection are described. A server receives a plurality of routing tokens for establishing a service connection between a service node and the server along a network path through a plurality of network devices. The routing tokens can be validated by a corresponding network device. The server transmits a packet including the routing tokens to a first network device. The first network device validates a first routing token associated therewith, then directs the packet along the network path to a second network device, and so forth, until each of the network device receives and validates their routing token. The server establishes a cryptographic context between the service node and server for establishing a secure channel between the service node and the server. The server transmits a service node routing token to the service node via the secure channel for validation.
