20130121491 | SYSTEM AND METHOD OF CREATING AND SENDING BROADCAST AND MULTICAST DATA - 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. | 05-16-2013 |
20130031620 | LOCALIZED NETWORK AUTHENTICATION AND SECURITY USING TAMPER-RESISTANT KEYS - 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. | 01-31-2013 |
20110264815 | Subnet Box - The invention provides an external in-line device (“Subnet Box”) placed between a network and an access point to achieve secure Wi-Fi communications without needing to modify the access point. The Subnet Box comprises an embedded token and will authenticate users based on pre-stored access rights. In at least one embodiment of the invention, the Subnet Box comprises: a first communications port for intercepting data packets communicated to and from a wired communications network; a second communications port for intercepting data packets communicated to and from a wireless access point, wherein the wireless access point is an edge device of the wired communications network; a database comprising a number of serial numbers each associated with a client token and a secret cryptographic key; and a processor for determining whether a computing device having a client token can access the wired communications network via the wireless access point. The processor establishes a secure tunnel between the computing device and the first communications port. | 10-27-2011 |
20110194695 | System And Method Of Creating And Sending Broadcast And Multicast Data - 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. | 08-11-2011 |
20110138170 | SYSTEM AND METHOD OF PER-PACKET KEYING - A method of per-packet keying for encrypting and decrypting data transferred between two or more parties, each party having knowledge of a shared key that allows a per-packet key to differ for each packet is provided. Avoiding the use of a static session key during encryption offers several advantages over existing encryption methods. For example, rejecting packets received with duplicate sequence numbers, or sequence numbers that are beyond a specified deviation range mitigates Replay Attacks. | 06-09-2011 |

20110044453 | SYSTEM AND METHOD OF ENCRYPTED MEDIA ENCAPSULATION - A system for and method of media encapsulation is presented. The method may include receiving, via an audio digitizer, a plurality of packets of data and compressing, via a codec, the plurality of packets of data. The method may also include queuing the plurality of packets of data in a queue and encrypting, via a filter, payloads of at least two of the plurality of packets of data in the queue into a single payload. The method further include transmitting the single payload in a single encrypted data packet. | 02-24-2011 |
20110016323 | REMOTE SECURE AUTHORIZATION - 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. This allows the enterprise network token to gain secure access to the temporary key of the client token, thereby allowing the enterprise network token to securely provision the remote client token with the appropriate enterprise Network Keys. | 01-20-2011 |
20110004759 | MASS SUBSCRIBER MANAGEMENT - 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. | 01-06-2011 |
20100031063 | System for and Method of Remote Secure Backup - Systems and methods for registering a module for backup, backing up a module, and restoring a backed up module are provided. | 02-04-2010 |
20100017867 | SELF-MANAGEMENT NETWORK ACCESS USING LOCALIZED ACCESS MANAGEMENT - The invention provides a method and system for locally tracking network usage and enforcing usage plans at a client device. In an embodiment of the invention, a unique physical key, or token, is installed at a client device of one or more networks. The key comprises a usage application and one or more access parameters designated the conditions and/or limits of a particular network usage plan. Upon initial connection to the network, the usage application grants or denies access to the network based on an analysis of the current values of the access parameters. Therefore, network usage tracking and enforcement is made simple and automatic without requiring any back-end servers on the network while still providing ultimate flexibility in changing billing plans for any number of users at any time. | 01-21-2010 |
