    摘要： A data hashing system operative to hash an incoming string of message words is an object of the present invention. The system generates a hash value tag comprising a deterministic random number string which uniquely identifies the incoming string. The system comprises at least first and second register arrays, at least one 1-way functionality in at least pseudo-randomizing function; and a set of at least first and second orthogonal feedback word stream generators operative to generate a set of at least first and second orthogonal feedback streams of message words respectively, including applying respective permutations to the incoming string. Wherein the first and second feedback streams are combined into the first and second register arrays respectively, the at least pseudo-randomizing functionality accepts input from the register arrays and generates at least pseudo-random output which, in combination with a present word in the incoming string, is provided to the stream generators, and the first feedback stream is a first function of a present word in the incoming stream and the second feedback stream is a second function of a present and previous words, in the incoming stream.

    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.

    摘要： An arrangement, system, and methods for creating and distributing authenticated personal information for users of network services and participants in social surveys, and in chat rooms and other forums. A trusted organization verifies that personal information presented by a user is correct, and authenticates the information in an encapsulated form as “certified profiles” within a smart card or other secure portable hardware device issued to the user Certified profiles are authenticated by digital signatures of the trusted organization and the profile users. Personal information in certified profiles can be in raw and/or in statistically-processed and abstracted form, and can be tailored by the user for specific needs to include whatever personal information is required, and to exclude all other personal information. By the use of unique aliases, it is possible for users to anonymously access restricted network sites and participate in surveys, while still satisfying recipients that supplied personal information is accurate, and for surveys that the user has not responded to the same survey more than once. Users enroll for certified profiles via trusted enrollment vendors who market the service to the public and also make hardware and software available to users for managing, maintaining, and distributing the certified profiles.
