中文拼音 [hāxīhánshǔ]
哈希函數
英文
hash function-
Hash functions are fundamental to modern cryptography
哈希函數是現代密碼系統的基礎。The general purpose hash function algorithm library contains implementations for a series of commonly used additive and rotative string hashing algorithms in the c + + programming language
通用哈希函數運演算法則庫包括一系列通常使用的附加的或者循環的字元竄散列法運演算法則,在c + +程序語言中。Serves as a hash function for a particular type
用作特定類型的哈希函數。The basic requirements for a cryptographic hash function are
加密哈希函數的基本要求是:Serves as a hash function for this object
作為此對象的哈希函數。Examples of well - known hash functions are md2 and and sha
較為熟知的哈希函數的示例有md2和sha 。Serves as a hash function for the current
對象的一個哈希函數。This process also uses hash functions
此過程還使用哈希函數。We design two different method to build the m - tree called static method and dynamic method separately, and we improve the dynamic initialization process of m - tree scheme by utilizing the dh algorithm. this improvement reduces the encryption cost efficiently in the initialization process. by taking stock of disparity cost between the m - tree and lkh sheme, we found that the encryption cost in joining and leaving operation achieve balance when r = 19
設計了動態和靜態兩種m樹的建立方法,並利用哈希函數改進了動態的初始化過程,減少了初始化過程的加密開銷;總結歸納出skdc , lkh和m樹三種方案的性能分析表;通過觀察m樹和lkh方案開銷差隨r的變化,發現當r = 19時,加入和離開操作的加密開銷達到平衡。Computes a hash - based message authentication code hmac using the
哈希函數計算基於哈希值的消息驗證代碼( hmac ) 。A hash - based message authentication code hmac uses a hash function where data is hashed by iterating a basic compression function on blocks of data
基於哈希的消息驗證代碼( hmac )使用一個哈希函數,通過在數據塊上迭代基本壓縮函數來計算數據的哈希值。It is possible for a hash function to generate the same hash code for two different keys, but a hash function that generates a unique hash code for each unique key results in better performance when retrieving elements from the hash table
一個哈希函數能夠為兩個不同的鍵生成相同的哈希代碼,但從哈希表檢索元素時,為每一唯一鍵生成唯一哈希代碼的哈希函數將令性能更佳。To use a public - key system to digitally sign a message, the sender first applies a hash function to the message to create a message digest
若要使用公鑰系統對消息進行數字簽名,發送方先向該消息應用哈希函數以創建消息摘要。In proc. the 4th conference on security in communication networks scn 04, amalfi, italy, september 8 - 10, 2004, springer - verlag, lncs 3352, pp. 165 - 179

是一個安全的、單向的哈希函數,把任意長度的數據轉化成固定長度的校驗和/哈希碼。For example, a hash function for a string might take the ascii codes of each character in the string and add them together to generate a hash code
例如,一個字元串的哈希函數可以採用該字元串中每一字元的ascii代碼並它們添加到一起來生成一個哈希代碼。Message authentication code hash functions are commonly used with digital signatures to sign data, while message detection code hash functions are used for data integrity
消息身份驗證代碼( mac )哈希函數通常與數字簽名一起用於對數據進行簽名,而消息檢測代碼( mdc )哈希函數則用於數據完整性。10 goldwasser s, micali s, rivest r. a digital signature scheme secure against adaptive chosen - message attacks. siam journal of computing, 1998, 17 : pp. 281 - 308
