- in classical cryptography, because of the passive eavesdropping, the absolute security of secure key is impossible
由于被動竊聽的存在，通信雙方在傳輸信道上建立絕對安全的密鑰是不可能的。 - quantum cryptography ( qc ) is the combination of classical cryptography and quantum mechanics . the characteristics of quantum mechanics, such as no-cloning theorem and heisenberg's uncertainty principle, provide the perfect secrecy for quantum cryptographic communication
量子密碼學是密碼學與量子力學結(jié)合的產(chǎn)物,利用量子不可克隆定理和海森堡測不準原理等量子特性，量子密碼通信理論上已經(jīng)證明是絕對安全。 - 1 . digital image scrambling digital image scrambling comes from the algorithms used by the classical cryptography in the early time . digital image is considered as a two dimension matrix, and when the permutation transform is executed, the digital image is disturbed and the way for protecting the digital image is obtained
本文所做的創(chuàng)新工作總結(jié)如下：1數(shù)字圖象置亂數(shù)字圖象置亂起源于經(jīng)典的密碼學早期所使用的一些密碼算法，把數(shù)字圖象看成一個二維的矩陣，對這個矩陣進行排列變換，使數(shù)字圖象變成一幅雜亂無章的圖象，達到對圖象進行擾亂的目的。
