    Patent number: 7487353
    Abstract: A method for transferring data between a first computer and a second computer is provided. The first computer sends a request to start a session, an encrypted session ID, and an encrypted hash value to the second computer. The second computer receives the request, decrypts the encrypted hash value, independently determines a hash value and compares the independently determined value to the decrypted value. If they match, the second computer starts a session with the first computer. Subsequently, the first computer sends a request to download or upload data, an encrypted ID, an identity of the file, and an encrypted hash value to the second computer in a second connection in the session. The second computer receives the request, decrypts the encrypted hash value, independently determines a hash value and compares the independently determined value to the decrypted value. If they match, the second computer processes the request.
