ABSTRACT:
A method for the secure transmission of data from a distributor to a client over a computer network. The method includes encrypting the data using an encryption confidentiality key known to the client, but not the distributor. The method also includes storing the encrypted data at the distributor and generating a message by further encrypting the encrypted data using an encryption transmission key. The corresponding transmission decryption key is also known by the client. Also, the method includes transmitting the generated message to the client.
