Improvement of Chang-Wu broadcasting cryptosystem using geometric properties of lines

چکیده
In 1991, Chang and Wu proposed a broadcasting cryptosystem using interpolating polynomials and geometric properties of circles. Nevertheless, the Chang-Wu scheme can be further enforced by using a time-variant parameter and a one-way function to protect legal receivers’ secrets from being disclosed. The authors present an improvement of the Chang-Wu scheme using geometric properties of lines. This improvement repairs the security flaws inherent in the original Chang-Wu scheme, whde requiring fewer public parameters and less computing time.

Broadcasting Cryptosystem in Computer Networks Using Geometric Properties of Lines
In 1997, Wu and Wu proposed an improvement of the Chang-Wu broadcasting cryptosystem using geometric properties of lines. The Wu-Wu scheme gave a better performance and required fewer public parameters than the Chang-Wu scheme. In this paper the authors propose an improvement to the Wu-Wu scheme using geometric properties of line. This improvement reduces the computation and significantly decre...
متن کاملImproving the Rao-Nam secret key cryptosystem using regular EDF-QC-LDPC codes
This paper proposes an efficient joint secret key encryption-channel coding cryptosystem, based on regular Extended Difference Family Quasi-Cyclic Low-Density Parity-Check codes. The key length of the proposed cryptosystem decreases up to 85 percent using a new efficient compression algorithm. Cryptanalytic methods show that the improved cryptosystem has a significant security advantage over Ra...
متن کاملInvestigation of Improvement in Georeferencing of Urban Analog Maps using the Geometric Elements and Genetic Algorithm
A large number of civil registries are available as analog maps that require georeferencing. Besides the quality of the analog maps and control points, the algorithm used for georeferencing also affects the accuracy of the map and the carried out geometrical calculations which indicates the need to study modern Georeferencing Methods. This requires the adoption of georeferencing optimization mo...

متن کاملEEH: AGGH-like public key cryptosystem over the eisenstein integers using polynomial representations
GGH class of public-key cryptosystems relies on computational problems based on the closest vector problem (CVP) in lattices for their security. The subject of lattice based cryptography is very active and there have recently been new ideas that revolutionized the field. We present EEH, a GGH-Like public key cryptosystem based on the Eisenstein integers Z [ζ3] where ζ3 is a primitive...
