Provably Secure Partially Blind Signature Scheme Based on Quadratic Residue
Partially blind signature schemes are the most important ingredient for anonymity in off-line e-cash system. In this paper, a new approach to setup formal security arguments in random oracle model for factorization based partially blind signature schemes is presented. Then a provably secure and efficient scheme based on quadratic residue is proposed. The approach also allows one to give formal ...

متن کاملLong Quadratic Residue Codes
A long standing problem has been to develop “good” binary linear block codes, C, to be used for error-correction. The length of the block is denoted n and the dimension of the code is denoted k. So in this notation C ⊆ GF (2) is a k-dimensional subspace. Another important parameter is the smallest weight of any non-zero codeword, d. This is related to error-correction because C can correct [d−1...
متن کاملOn quadratic residue codes and hyperelliptic curves
For an odd prime p and each non-empty subset S ⊂ GF (p), consider the hyperelliptic curve XS defined by y = fS(x), where fS(x) = Q a∈S(x− a). Using a connection between binary quadratic residue codes and hyperelliptic curves over GF (p), this paper investigates how coding theory bounds give rise to bounds such as the following example: for all sufficiently large primes p there exists a subset S...
متن کاملTunable phase-shifted fiber Bragg grating based on femtosecond laser fabricated in-grating bubble.
We present a type of phase-shifted fiber Bragg gratings based on an in-grating bubble fabricated by femtosecond (fs) laser ablation together with a fusion-splicing technique. A microchannel vertically crossing the bubble is drilled by fs laser to allow liquid to flow in or out. By filling different refractive index (RI) liquid into the bubble, the phase-shift peak is found to experience a linea...
