| 20090169013 | SYSTEM FOR AND METHOD OF CRYPTOGRAPHIC PROVISIONING - A system for and method of securely provisioning a module with cryptographic parameters, such as cryptographic keys and key tables, is presented. Such modules may be used to enable encrypted communications between mobile phones to which they are coupled. The system and method prevent a malevolent individual involved in manufacturing the modules from compromising the security of the module. In particular, the modules are provisioned by an entity different from the manufacturer. | 07-02-2009 |
| 20090172412 | SYSTEM FOR AND METHOD OF AUTO-REGISTRATION WITH CRYPTOGRAPHIC MODULES - A system for and method of registering devices an applications with cryptographic modules is presented. The system and method prevent devices and applications from operating in conjunction with cryptographic modules unless such devices and applications have previously been registered with the module. | 07-02-2009 |
| 20090204393 | Systems and Methods For Adaptive Multi-Rate Protocol Enhancement - A method of processing a codec sample is provided. The method includes: removing from a first portion of the codec sample, a first number of first information bits. The first information bits are indicative of frame information associated with the codec sample. The method also includes inserting at the first portion of the codec sample from a second portion of the codec sample, a second number of data bits. The first number of the first information bits is greater than or equal to the second number of the data bits. The method also includes removing the second portion of the codec sample. The method may also include encrypting and decrypting the codec sample. In some embodiments, the codec sample is an adaptive multi-rate codec sample. In some embodiments, the adaptive multi-rate codec sample is a 5.15 mode adaptive multi-rate codec sample. | 08-13-2009 |
| 20090268902 | SYSTEM FOR AND METHOD OF CRYPTOGRAPHIC PROVISIONING - A system for and method of securely provisioning a module with cryptographic parameters, such as cryptographic keys and key tables, is presented. Such modules may be used to enable encrypted communications between mobile phones to which they are coupled. The system and method prevent a malevolent individual involved in manufacturing the modules from compromising the security of the module. In particular, the modules are provisioned by an entity different from the manufacturer. | 10-29-2009 |
| 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 |

| 20080313458 | 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. | 12-18-2008 |
| 20080313464 | 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. | 12-18-2008 |
| 20090122984 | SECURE MOBILE TELEPHONY - An system for and method of providing end-to-end encrypted real-time phone calls using a commodity mobile phone and without requiring service provider cooperation is presented. The system and method improve upon prior art techniques by omitting any requirement for mobile phones that are specially manufactured to include end-to-end encryption functionality. | 05-14-2009 |
| 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 |
| 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 |
| 20110055574 | 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. | 03-03-2011 |
| 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 |
