Abstract
A method of encrypting broadcast and multicast data communicated between two or more parties, each party having knowledge of a shared key, is provided. The key is calculated using values, some of which are communicated between the parties, so that the shared key is not itself transferred. Avoiding the transfer of the key offers several advantages over existing encryption methods.
