This paper gives a comprehensive listing of security issues in the systems and analyzes three classes of attacks which are based on mathematical structure of the group which is used in the schemes, the disclosed information of the subgroup and implementation details respectively. The analysis will, in turn, allow us to motivate protocol design and implementation decisions.展开更多

文摘Discrete logarithm based cryptosysterns have subtle problems that make the schemes vulnerable. This paper gives a comprehensive listing of security issues in the systems and analyzes three classes of attacks which are based on mathematical structure of the group which is used in the schemes, the disclosed information of the subgroup and implementation details respectively. The analysis will, in turn, allow us to motivate protocol design and implementation decisions.
文摘In reinventing itself, the Shanghai Cooperation Organization should stick to being a regional cooperative organization guided by a new concept and prioritizing security and economic cooperation. Meanwhile, brash expansion of the organization will cause a lot of problems.
