| 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 |
| 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 |
| 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 |
| 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 |
