This paper presents a multivariate public key cryptographic scheme over a finite field with odd prime characteristic. The idea of embedding and layering is manifested in its construction. The security of the scheme is analyzed in detail, and this paper indicates that the scheme can withstand the up to date differential cryptanalysis. We give heuristic arguments to show that this scheme resists all...
This paper proposes a new public key signature scheme based on multivariate quadratic polynomials over a finite field with odd prime characteristic. This signature scheme has a very simple internal transformation, allowing for efficient signature generation and verification. The security of the scheme is analyzed in detail. The result indicates that the new signature scheme can withstand all known...
