Patent number: 8301891Abstract: The invention provides a secure Wi-Fi communications method and system. In an embodiment of the invention, unique physical keys, or tokens, are installed at an access point and each client device of the network. Each key comprises a unique serial number and a common network send cryptographic key and a common network receive cryptographic key used only during the authentication phase by all components on the LAN. Each client key further includes a secret cryptographic key unique to each client device. During authentication, two random numbers are generated per communications session and are known by both sides of the wireless channel. Only the random numbers are sent across the wireless channel and in each case these numbers are encrypted. A transposed cryptographic key is derived from the unique secret cryptographic key using the random numbers generated during authentication. Thus, both sides of the wireless channel know the transposed cryptographic key without it ever being transmitted between the two.Type: GrantFiled: November 9, 2010Date of Patent: October 30, 2012Assignee: Koolspan, Inc.Inventor: Anthony C.

Publication number: 20110016323Abstract: The present invention discloses a technique provisioning network cryptographic keys to a client when direct physical transfer is not feasible. In an embodiment of the invention, a client token generates a temporary key encrypted with a first secret key known only in a master token database and passes this on to an enterprise network token of a network to which service is requested. The enterprise network token then further encrypts the encrypted temporary key with a second secret key and passes that on to the master token database. Since the second secret key is also known by the master token database, the originally encrypted temporary key can be securely decoded only by a master token coupled to the master token database. The decrypted temporary key can then be re-encrypted with a key known only by the enterprise network token and the master token, and returned to the enterprise network token.Type: ApplicationFiled: September 24, 2010Publication date: January 20, 2011Applicant: Koolspan, Inc.Inventor: Anthony C.

Publication number: 20110004759Abstract: An authentication and mass subscriber management technique is provided by employing a key table derived as a subset of a larger key pool, a network edge device, and authentication tokens attached on both the network edge device and on a subscriber's computing device. The network edge device and subscriber's computing device are provided with secure, tamper-resistant network keys for encrypting all transactions across the wired/wireless segment between supplicant (subscriber) and authenticator (network edge device). In an embodiment of the invention, a secure, secret user key is shared between a number of subscribers based upon commonalities between serial numbers of those subscribers' tokens. In another embodiment of the invention, a unique session key is generated for each subscriber even though multiple subscribers connected to the same network connection point might have identical pre-stored secret keys.Type: ApplicationFiled: September 15, 2010Publication date: January 6, 2011Applicant: KOOLSPAN, Inc.Inventor: Anthony C.

Patent number: 7607015Abstract: A system and method for consistent authentication and security mechanism to enable a client device to easily roam from one network to another without requiring the client to manually change network configurations is disclosed. In one embodiment, a client device listens for a “beacon frame” broadcast from a Wi-Fi access point. The beacon frame identifies the basic service set identifier (BSSID) of the access point. A tamper-resistant token, or client key, installed at the client device stores a set of authentication parameters, e.g., cryptographic keys, for each Wi-Fi network the client is permitted to access. Each set of authentication parameters is associated with a particular BSSID. Using the BSSID received from the access point, the client device identifies and implements the appropriate set of authentication parameters necessary to authenticate the client device according to an authentication process generally accepted by all the Wi-Fi networks potentially servicing the client.Type: GrantFiled: October 7, 2003Date of Patent: October 20, 2009Assignee: Koolspan, Inc.Inventor: Anthony C.
