Archaeological studies of chinese music and military cryptograph 中國樂曲考古學與軍事密碼學的比較
Its key idea of this project is to balance the transmitting efficiency and the transmitting cryptograph 針對這些存在的問題,筆者提出了一種改進方案? ? bb84 +量子密鑰分配方案。
The difficulty of decoding based on cryptograph and public key is equal to the difficult } " of dividing the product of two big prime numbers 從一個公開密鑰和密文中恢復出明文的難度等價于分解兩個大素數(shù)之積。
Cryptology is the core of the information security . modern cryptograph divides into the public key system and the private key system 密碼學是信息安全技術的核心,現(xiàn)代密碼體制分為公鑰體制和私鑰體制兩大類。
In this paper , the security of the wtls is analysed . now elliptic curve and ripemd160 cryptograph algorithm is two latest methods and do not easily attack 橢圓曲線法和ripemd ? 160是兩種目前較新的加密算法,且不易被破解,本文初步分析和研究了這兩種方法。
Last we describe the functions of the system in brief in the sixth chapter , we introduce the cryptograph protocol and the sollltion of some typical cryptosystems 第六章介紹了密碼協(xié)議與典型密碼系統(tǒng)的實現(xiàn)方案。說明了密碼協(xié)議及其在安全系統(tǒng)中的應用,并分析了目前廣泛應用的典型密碼系統(tǒng)實現(xiàn)方案。
This thesis mainly analyses security in the wtls and reasons for defects , study two solutions of security in the wtls which are elliptic curve and ripemd160 cryptograph algorithm 本文主要分析了wtls的安全漏洞及其存在的原因,并在此基礎上研究了兩種解決wtls安全問題的方法? ?橢圓曲線和ripemd ? 160算法。
The paper introduces a sort of encrypted algorithm which comparied with the original length of cryptograph , the length of encrypted cryptograph will base on the difference of the encrypted information piece length to minish 本文介紹了一種加密后的密文長度與原明文長度文相比,依據(jù)所選加密信息塊長度的不同而做相應減小的加密算法。
Public key cryptography , combined with the traditional symmetric cryptograph and the message digest technology , can provide confidentiality , integrity and proof of origin . it ' s the foundation of many secure applications 公鑰密碼技術結合傳統(tǒng)的對稱密碼技術及信息摘要技術,可提供信息的保密性、完整性和信源確認,是多種安全應用的基礎。
