Partial Rigidity of CR Embeddings of Real Hypersurfaces into Hyperquadrics with Small Signature Difference
Partial Rigidity Real Hypersurfaces Signature Difference
2010/11/11
We study the rigidity of holomorphic mappings from a neighborhood of a Levi-nondegenerate CR hypersurface $M$ with signature $l$ into a hyperquadric $Q_{l'}^{N} \subseteq \mathbb{CP}^{N+1}$ of larger ...
Cryptanalysis on Chen-Qiu-Zheng blind signature scheme
Blind Signatures Security Privacy Cryptology
2010/9/10
Chen, Qiu, and Zheng proposed a Rabin-like blind signature scheme, which is based on the square-root problem. Although their scheme is simple and efficient, it can be compromised when choosing some pa...
A novel identity-based society oriented signature scheme with anonymous signers
RSA cryptosystem society signature
2010/9/15
Recently, Saeedina proposed an identity-based society oriented signature scheme with anonymous signers based on the Quillou-Quisquater signature scheme. The scheme is identity-based and the signatures...
