摘要： An extension of the serial/parallel Montgomery modular multiplication method with simultaneous reduction as previously implemented by the applicants, adapted innovatively to perform both in the prime number and in the GF(2q) polynomial based number field, in such a way as to simplify the flow of operands, by performing a multiple anticipatory function to enhance the previous modular multiplication procedures.

摘要： A system for multi-factor security involving multiple secure devices that distribute the secured functions of the system over the different devices, such that the loss or theft of any one of them does not compromise the overall security of the system. Moreover, a configuration of devices is also secure even if one of them has been attacked by malicious software agents, such as “keyboard sniffers”. A novel contactless smart card reader (200) is presented that incorporates a transceiver antenna (220) within a keypad (210) of a device used with contactless smart cards (100). When the card (100) is pressed against the device's keypad (210), the transceiver (220) of the device establishes a session with the smart card (100). A variety of systems are presented, including those using mobile telephones, computer-interfaced card readers, personal digital appliances, and television set-top box remote controllers.
摘要翻译：一种涉及多个安全设备的多因素安全系统，它们通过不同的设备分发系统的安全功能，使得任何一个安全设备的丢失或被盗都不会损害系统的整体安全性。此外，即使其中一个已经被恶意软件代理（例如“键盘嗅探器”）攻击，设备的配置也是安全的。提出了一种新颖的非接触式智能卡读取器（200），其在与非接触式智能卡（100）一起使用的设备的键盘（210）内并入收发器天线（220）。当卡（100）被按压在设备的键盘（210）上时，设备的收发器（220）与智能卡（100）建立会话。提出了各种系统，包括使用移动电话，计算机接口读卡器，个人数字设备和电视机顶盒遥控器的系统。

摘要： Systems and methods are disclosed, especially designed for very compact hardware implementations, to generate random number strings with a high level of entropy at maximum speed. For immediate deployment of software implementations, certain permutations have been introduced to maintain the same level of unpredictability which is more amenable to hi-level software programming, with a small time loss on hardware execution; typically when hardware devices communicate with software implementations. Particular attention has been paid to maintain maximum correlation immunity, and to maximize non-linearity of the output sequence. Good stream ciphers are based on random generators which have a large number of secured internal binary variables, which lead to the page synchronized stream ciphering. The method for parsed page synchronization which is presented is especially valuable for Internet applications, where occasionally frame sequences are often mixed. The large number of internal variables with fast diffusion of individual bits wherein the masked message is fed back into the machine variables is potentially ideal for message authentication procedures.
