| 20090024352 | Method, Device and System For Verifying Points Determined on an Elliptic Curve - Conventional cryptographic methods that are based on elliptic curves are prone to side-channel attacks. Previously known methods for preventing side-channel attacks have the disadvantage of requiring high arithmetic capacity and a large amount of available memory space. The proposed method overcomes said disadvantage by using a process for verifying points on elliptic curves which saves arithmetic capacity and memory space. | 01-22-2009 |
| 20090235073 | Authentication method and communications system used for authentication - An authentication method authenticates between subscribers of a communications system using an asymmetric elliptic curve encryption algorithm. The method involves providing a first and at least one second subscriber having a first or second secret key known only to the respective subscriber and a public key; authenticating an inquiry transmitted by the first subscriber with respect to the validity of the first certificate contained therein and associated with the first subscriber; calculating the response of the second subscriber associated with the inquiry; randomized encryption of the calculated response and a second certificate associated with the second subscriber using the public key; decryption and authentication of the response transmitted by the second subscriber with respect to the validity of the second certificate contained therein. | 09-17-2009 |
| 20090292921 | METHOD FOR THE ENCRYPTED DATA EXCHANGE AND COMMUNICATION SYSTEM - The embodiments relate to a method for the encrypted data exchange between subscribers of a communication system using cryptography based on elliptical curves, wherein upon a query by a first subscriber a scalar multiplication is calculated by the second subscriber, wherein merely part of the result of the scalar multiplication is returned to the first subscriber as a response. The invention relates to a communication system. | 11-26-2009 |
| 20100172490 | METHOD FOR THE SECURE DETERMINATION OF DATA - The aim of the embodiments is to provide a method for the secure processing of data, in which security is increased in relation to side channel attacks. To achieve this, operation codes for commanding co-processors are determined, for example for the bit-dependent transposition of register contents. The solution exploits the fact that as a result of the technical configuration for the co-processor, a shift of register contents, for example from register A to register B cannot be differentiated from the exterior from a shift from register A to register C. | 07-08-2010 |
| 20110068894 | METHOD FOR AUTHENTICATING AN RFID TAG - To ensure data protection in an authentication method for use in an RFID system in accordance with the challenge-response protocol, the data communication between RFID reader and RFID tag is usually encrypted in addition. Such an authentication can be designed to an arbitrary degree of complexity and therefore inevitably requires a high level of investment in hardware and software resources. An RFID tag has a display, wherein the response is displayed on the display of the RFID tag and is read in by the RFID reader by an optical scanner. The response of the RFID tag can therefore be read out only when there is direct visual contact. | 03-24-2011 |
| 20110107097 | METHOD FOR ENCODED DATA EXCHANGE AND COMMUNICATION SYSTEM - In a system and method for encrypted data exchange between entities (users) of a communication system using cryptography based on elliptic curves, in response to a challenge of a first user a scalar multiplication is calculated by the second user, wherein only part of the result of the scalar multiplication is sent back as response to the first user. | 05-05-2011 |

| 20080196313 | Door and Door Frame Assembly - Door and frame assemblies are disclosed by the present application. In one exemplary embodiment, the a door is connected to a door frame, such that the door is moveable between an open position and a closed position. Activation of a trigger causes a door frame coupling arrangement to couple the door frame to the door in a closed position to thereby inhibit movement of the door relative to the frame. In another exemplary embodiment, a door is coupled to a door frame by a hinge. The hinge is configured to move the door in translation as the door is rotated from the open position to the closed position. For example, the hinge may move the door downward, toward the sill, when the door is moved from the open position to the closed position. | 08-21-2008 |
| 20100251620 | ENTRY SYSTEM WITH WATER INFILTRATION BARRIER - The present application discloses embodiments of entry systems that minimize water infiltration due to a wind driven rain. In one embodiment, the entry system includes a corner pad that includes an upper portion that seals against the weather strip when the door is closed and a lower portion that is spaced apart from the weather strip to form a gap between the lower portion and the weather strip. The lower portion seals against the door when the door is closed. | 10-07-2010 |

| 20080205639 | Method for securely encrypting or decrypting a message - A method for securely encrypting or decrypting a message or for generating or verifying a digital signature in a message, in which the message is subjected, with the aid of a processor, to a mathematical operation using a key (k) which can be represented in the form of a binary number with a sequence of bits, and computational operations are sequentially carried out on auxiliary variables for each bit. The dependence of the computational result on the values of individual bits is taken into account by reading the memory addresses from the auxiliary variables and assigning them to address variables. The difference between the addresses is calculated and, depending on the respective current bit, is added to, or subtracted from, the computer addresses. The assignment of the auxiliary variables to the address variables can thus be interchanged. As a result, the order and selection of the computational operations is controlled on the basis of bits without the program sequence having to contain jump instructions. | 08-28-2008 |
