Patent ID: 7100048

Claim:
A method for efficient encryption and decryption of Internet, Intranet, or e-mail messages, comprising the steps of: providing a sending unit in communication with an integrated encryption circuit embedded with an encryption algorithm; encrypting a message at said sending unit; appending to the message at said sending unit a receiver's unencrypted IP address; appending to said message a receiver's encrypted IP address; sending said encrypted message with said unencrypted IP address and said encrypted IP address to a receiving unit; providing said receiving unit having an integrated encryption circuit embedded with a decryption algorithm; receiving with said receiving unit said encrypted message with said unencrypted IP address and said encrypted IP address; decrypting with said receiving unit said encrypted IP address, thereby resulting in a decrypted IP address; storing said decrypted IP address in a first register built into said integrated encryption circuit within said receiving unit; storing said unecrypted IP address in a second register built into said integrated circuit within said receiving unit; means for comparing said second register storing unencrypted IP address to said first register storing said decrypted IP address; decrypting said message if said second register storing said unencrypted IP address matches said first register storing said decrypted IP address; and means for halting decryption process if said second register storing said unencrypted IP address does not match said first register storing said decrypted IP address.
