Cryptography > Communication System Using Cryptography > Wireless Communication > Synchronization SynchronizationSynchronization patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.08/16/07 - 20070189538 - Rapid acquisition of state vectors in an encrypted data communication system A state vector acquisition technique for a counter-based cryptographic data communication system is disclosed. The acquisition technique facilitates receipt of the state vector components (the short component and the long components) in any chronological order. The state vector components are saved upon receipt, and a counter for each long component ... 03/15/07 - 20070058812 - Enforcing time-based transaction policies on devices lacking independent clocks A system and a method for operating a device that is not capable of independently maintaining a local time clock to enforce a time-based transaction policy that requires a reliable time reference. The device establishes a secure communications channel to one or more network-attached time sources and inquires of each ... 09/21/06 - 20060210080 - Key synchronization in a visual cryptographic system A system for visual cryptography comprises a server (1) for encrypting a series of images using a set of keys, a terminal (2) for displaying the encrypted images, a transmission medium (4) for transmitting the encrypting images from the server to the terminal (2), and a decryption device (3) for ... 08/31/06 - 20060193472 - Secure encryption system, device and method A system, device and method for encrypting plaintext information securely. The system includes a transmitting agent to generate and synchronize a first cipher stream using the plaintext information and a first key, to generate and synchronize a second cipher stream using a second key and a randomizing function to randomize ... 03/16/06 - 20060056637 - Method and apparatus for encrypting transmissions in a communication system Method and apparatus for encrypting transmission traffic at separate protocol layers L1, L2, and L3 so that separate encryption elements can be assigned to separate types of transmission traffic, which allows the implementation of different levels of encryption according to service requirements. Encryption elements use variable value inputs, called crypto-syncs, ... 09/08/05 - 20050195979 - System and method for limiting access to data A system and method for limiting access to data including a secured appliance. The secured appliance has limited responsiveness to received remote control data frames unless such remote control data frames include parameters matching those stored within the secured appliance. ... 09/01/05 - 20050190920 - System in a digital wireless data communication network for arranging end-to-end encryption and corresponding terminal equipment The invention concerns a system in a digital wireless data communication network for arranging end-to-end encryption in which the data communication network two or more pieces of terminal equipment are communicating with one another, including at least means for management of encryption parameters (TEK, IV), an encryption key stream generator, ... ### FreshPatents.com Support |
