Techniques for protecting data in cloud computing environments

摘要

A client computer runs a communicator employed to connect to a server computer in a cloud. The communicator is updated on a regular basis to update its algorithms for processing raw data into secured data. The server computer receives and validates the secured data, and attempts to update the communicator if the secured data is invalid. The server computer may deem the client computer as being infected when the update is reinitiated a predetermined number of times. The raw data may be restructured, or encrypted using an encryption scheme where the key used for the encryption is not provided to the receiver of the data. The algorithm for data restructuring and encryption may be included in the update to the communicator. Communication between the client computer and the server computer may be on a dynamically selected channel indicated in a previous communication.
