一种使用多块矩阵的公钥密码学

A public key cryptography using multinacci block matrices

Munesh Kumari, Jagmohan Tanti

摘要:

本文提出了一种基于有限域Fp上广义Fibonacci数递归分块矩阵的公钥密码学。为此,我们定义了一种上三角矩阵,即在对角位置上包含多个矩阵的多个分块矩阵,并得到了它的一些代数性质。此外,我们还建立了一种在终端用户处进行密钥协商的方法,从而提高了密码学的效率。所提出的加密算法具有较大的密钥空间,其安全性依赖于离散对数问题(DLP)。

英文摘要:

In this paper, we have proposed a public key cryptography using recursive block matrices involving generalized Fibonacci numbers over a finite field Fp. For this, we define multinacci block matrices, a type of upper triangular matrix involving multinacci matrices at diagonal places and obtained some of its algebraic properties. Moreover, we have set up a method for key element agreement at end users, which makes the cryptography more efficient. The proposed cryptography comes with a large keyspace and its security relies on the Discrete Logarithm Problem(DLP).
