  • Publication number: 20140105403
    Abstract: Methods and apparatus for generating a private-public key pair, for encrypting a message for transmission through an unsecure communication medium (30), and for decrypting the message are disclosed. The methods are based on the well-known McEliece cryptosystem or on its Niederreiter variant. More general transformation matrices Q are used in place of permutation matrices, possibly together with an appropriate selection of the intentional error vectors. The transformation matrices Q are non-singular n×n matrices having the form Q=R+T, where the matrix R is a rank-z matrix and the matrix T is some other matrix rendering Q non-singular. The new Q matrices, though at least potentially being dense, have a limited propagation effect on the intentional error vectors for the authorized receiver. The use of this kind of matrices allows to better disguise the private key into the public one, without yielding any further error propagation effect.

  • Patent number: 8680042
    Abstract: Sickle cell anemia is a genetic disease characterized by red blood cells that assume an abnormal, rigid, sickle shape. Acute complications of Sickle cell anemia are treated symptomatically with analgesics and transfusions, and a prophylactic treatment of sickle cell crisis is long term application of hydroxyurea. According to the present invention, an N-methyl D-aspartate receptor (NMDAR) blocker is used for the treatment of sickle cell anemia and for manufacture of a medicament for the treatment of sickle cell anemia. Moreover, a method for screening for a compound effective in the treatment of sickle cell anemia comprises contacting a candidate compound with the NMDAR and selecting said candidate compound as effective if it is found to selectively reduce activity of the NMDAR.

  • Publication number: 20140050760
    Abstract: The invention relates to an infectious arenavirus particle that is engineered to contain a genome with the ability to amplify and express its genetic information in infected cells but unable to produce further infectious progeny particles in normal, not genetically engineered cells. One or more of the four arenavirus open reading frames glycoprotein (GP), nucleoprotein (NP), matrix protein Z and RNA-dependent RNA polymerase L are removed or mutated to prevent replication in normal cells but still allowing gene expression in arenavirus vector-infected cells, and foreign genes coding for an antigen or other protein of interest or nucleic acids modulating host gene expression are expressed under control of the arenavirus promoters, internal ribosome entry sites or under control of regulatory elements that can be read by the viral RNA-dependent RNA polymerase, cellular RNA polymerase I, RNA polymerase II or RNA polymerase III.

  • Publication number: 20130326315
    Abstract: An apparatus and method are disclosed for evaluating an input polynomial (p(x)) in a (possibly trivial) extension of the finite field of its coefficients, which are useful in applications such as syndrome evaluation in the decoding of cyclic codes. The apparatus comprises a decomposition/evaluation module (110) configured to iteratively decompose the input polynomial into sums of powers of the variable x, multiplied by powers of transformed polynomials, wherein each transformed polynomial has a reduced degree as compared to the input polynomial, and to evaluate the decomposed input polynomial. In another aspect, an apparatus and method of identifying errors in a data string based in a cyclic code are disclosed, which employ the Cantor-Zassenhaus algorithm for finding the roots of the error-locator polynomial, and which employ Shank's algorithm for computing the error locations from these roots.

  • Publication number: 20130303873
    Abstract: A hopper having a passage through which a medicine can be passed downward is provided. A part of a lower portion of the hopper is a deformable portion having flexibility, and the deformable portion is deformable so as to open and close the passage. According to this configuration, the deformable portion that is a part of the hopper is deformed to open and close the passage. Thus, there is no portion such as an opening and closing plate on which the medicine remains, thereby preventing a gap in which the medicine remains from being formed in the hopper, and preventing the medicine from easily remaining in the hopper.
