Cryptography > Communication System Using Cryptography > Position Dependent Or Authenticating Position Dependent Or AuthenticatingPosition Dependent Or Authenticating 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.07/26/07 - 20070172064 - Electronic device, control method thereof, security program and others An electronic device, a control method thereof and a security program are provided which are capable of preventing or suppressing the theft of the electronic device. The electronic device comprises mounting means for loading a portable recording medium and encrypted information write means for encrypting predetermined information using an encryption ... 05/24/07 - 20070116288 - System for managing keys and/or rights objects One or more rights objects (RO) files may be used for storing RO's preferably in the protected area available only to authenticated users. A RO navigation file is stored preferably in an unprotected public area containing status bits, where each status bit identifies whether a location in a RO file ... 05/24/07 - 20070116287 - Method for managing keys and/or rights objects One or more rights objects (RO) files may be used for storing RO's preferably in the protected area available only to authenticated users. A RO navigation file is stored preferably in an unprotected public area containing status bits, where each status bit identifies whether a location in a RO file ... 02/08/07 - 20070030972 - Cryptographic system and method for geolocking and securing digital information A method and apparatus for controlling access to digital information utilizes a location identity attribute that defines a specific geographic location. The location identity attribute is associated with the digital information such that the digital information can be accessed only at the specific geographic location. The location identity attribute further ... 01/18/07 - 20070014406 - Cryptographic key split binding process and apparatus A cryptographic key split combiner includes a number of key split generators for generating cryptographic key splits from seed data, and a key split randomizer for randomizing the key splits to produce a cryptographic key. The key split generators can include a random split generator for generating random key splits, ... 06/15/06 - 20060126842 - Method and system for generation of cryptographic keys and the like A method, and deterministic random bit generator system operating in accordance with the method, for generating cryptographic keys and similar secret cryptographic inputs which are hard to guess. A seed is input from an entropy source; and an initial state is generated as a function of the seed. When a ... 05/18/06 - 20060104447 - Discrete logarithm-based cryptography using the shafarevich-tate group Systems and methods for discrete logarithm-based cryptography using the Shafarevich-Tate group are described. In one aspect, a Shafarevich-Tate group is generated from an abelian variety. Data is encrypted or signed or a common secret is established as a function of a secret generated from the Shafarevich-Tate group. ... 05/04/06 - 20060093144 - Communications method for at least two system components of a motor vehicle In a communications system for at least two system components over a network connection, e.g., a CAN bus system of a motor vehicle, system components have ready in each case a prespecified, fixed number of test codes known only to them. Based on a time-variable signal which is accessible to ... 04/13/06 - 20060078122 - Location-based wireless messaging for wireless devices An apparatus and method of location-based wireless messaging wireless devices is described. The method includes the receipt of a location-based message request from a user of a wireless device desiring to receive a location-based message. Once the request is received, a spatial location of the wireless device is monitored. Once ... ### FreshPatents.com Support |
