摘要
本文利用分式分解定理构造两级(K,N)TCSS系统,分析了此系统的性能和优缺点,指出利用此系统,不仅具有(K,N)TCSS系统要求的性能,并且可以查验掌管子密钥人员的合法性,防止了主密钥的窜改或破坏。
According to the principles of determinant resolution, this paper presents a (K, N) TCSS system and analyses the performance, the advantage and the shortage of the system. It points that by using the system we not only can get the performance demanded by (K, N) TCSS system, but also can identity the legality of the persons who grasp the sub-cryptographic key, thus we can protect the main key from being changed and destroyed.
