Hybrid network encrypt/decrypt scheme

A method for a service provider to transmit decryption information in a secure manner, comprising:

• receiving a request for a service from a requestor over a bidirectional channel;
• authenticating the requestor;
• providing decryption information to the requestor over the bidirectional channel for use in decrypting the service;
• transmitting the service, encrypted with encryption information corresponding to the decryption information, over a unidirectional channel;
• changing the decryption information needed to decrypt the service throughout the transmission of the service;
• and
• providing the requestor with changes to the decryption information over the unidirectional channel.

A method for a client to receive decryption information from a service provider in a secure manner, comprising:

• requesting a service over a bi-directional channel;
• transmitting authentication information over the bi-directional channel;
• receiving first decryption information over the bi-directional channel;
• receiving the service over a unidirectional channel;
• decrypting the service using the first decryption information;
• receiving second decryption information over the unidirectional channel;
• and
• decrypting the service using the second decryption information.

A method for a service provider to transmit decryption information in a secure manner, comprising:

• receiving a request for a service from a requester via postal mail;
• authenticating the requestor;
• transmitting first decryption information to the requestor via postal mail for use in decrypting the service;
• transmitting the service, encrypted with encryption information corresponding to the first decryption information, over a unidirectional channel;
• generating second decryption information for use in decrypting the service at a later time;
• transmitting the second decryption information over the unidirectional channel;
• and
• transmitting the service, encrypted with encryption information corresponding to the second decryption information, over the unidirectional channel.

A method for a service provider to transmit decryption information in a secure manner, comprising:

• receiving a request for a service from a requestor;
• authenticating the requestor;
• installing first decryption information on a device of the requestor for use in decrypting the service;
• transmitting the service, encrypted with encryption information corresponding to the first decryption information, over a unidirectional channel;
• generating second decryption information for use in decrypting the service at a later time;
• transmitting the second decryption information over the unidirectional channel for reception by the requester;
• and
• transmitting the service, encrypted with encryption information corresponding to the second decryption information, over the unidirectional channel.
