摘要
该文由传统的钥匙分配问题入手,从正交投影的角度论述和分析了密钥空间中的向量A(密钥)在若干不同子空间上正交投影形成密钥分存方案的算法及数量,并且用C语言实现了密钥分存方案的算法,简述了编程实现算法的技术要点。算法不仅实现了密钥分解分存,而且对信息分解和安全分存给出了一条有效途径。
The ar ti cle begins with the traditional topic on assigning key.By means of orthogonal projection of vector A of key space on orthogonal subspace,it sets forth an alg orithm forming the scheme to assign key.The algorithm is realized in C languag e and the key point of programming technology is briefly described.The algorit hm not only can be used to decompose data key,but also be used to decompose in formation resulting in safe saving.
