SECURE MESSAGE ROUTING IN MULTI TENANT SYSTEM WITHOUT CONTENT INSPECTION

摘要

A method for message routing in a multi-tenant system includes encrypting an ID of a tenant with a public key that is generated for the tenant together with a corresponding private key; storing a set of the encrypted ID and the public key in both a device and a server of the multi-tenant system; transmitting from the device to the server a message comprising the set of the encrypted ID and the public key stored in the device; and detecting whether the message is directed toward a data store for the tenant by comparing the set comprised in the message and the set stored in the server.
