Method for establishing secure communication link between computers of virtual private network
First Claim
1. A method for accessing a secure computer network address, comprising steps of:
- receiving a secure domain name;
sending a query message to a secure domain name service, the query message requesting a secure computer network address corresponding to the secure domain name;
receiving a response message containing the secure computer network address corresponding to the secure domain name; and
sending an access request message to the secure computer network address using a virtual private network communication link.

Abstract
A technique is disclosed for establishing a secure communication link between a first computer and a second computer over a computer network. Initially, a secure communication mode of communication is enabled at a first computer without a user entering any cryptographic information for establishing the secure communication mode of communication. Then, a secure communication link is established between the first computer and a second computer over a computer network based on the enabled secure communication mode of communication. The secure communication link is a virtual private network communication link over the computer network in which one or more data values that vary according to a pseudo-random sequence are inserted into each data packet.
