例句與用法
- Pseudorandomness of camellia - like scheme
Camellia型方案的偽隨機(jī)性 - The sequences have good pseudorandomness as binary ones . just as q - ary generalized self - shrinking sequences , two parameters are chosen as the section key to strengthen the cryptosystem
和q元廣義自縮序列一樣，在加密的時候也可以選擇兩個參數(shù)作為密鑰使密碼體制更加牢固。 - 20 ramzan z , reyzin l . on the round security of symmetric - key cryptographic primitives . in advances in cryptology - crypto 2000 , lncs 1880 , springer - verlag , santa barbara , ca , usa , aug . 2000 , pp . 376 - 393 . 21 gilbert h , minier m . new results on the pseudorandomness of some block cipher constructions
可證安全理論研究的是分組密碼理想狀態(tài)下的安全性，不關(guān)注具體算法的安全性，更多的是對設(shè)計準(zhǔn)則的研究設(shè)計安全的分組密碼就是盡可能逼近理想狀態(tài)，逼近的過程就是不斷的降低假設(shè)條件。 - 18 iwata t , kurosawa k . on the pseudorandomness of the aes finalists - rc6 and serpent . in fast software encryption - fse 2000 , lncs 1978 , springer - verlag , new york , usa , april 2000 , pp . 231 - 243 . 19 iwata t , yoshino t , yuasa t , kurosawa k . round security and super - pseudorandomness of misty type structure
本文首先證明了5輪camellia型結(jié)構(gòu)對適應(yīng)性攻擊是偽隨機(jī)的然后證明了8輪camellia型結(jié)構(gòu)對適應(yīng)性攻擊是超偽隨機(jī)的最后討論了如何構(gòu)造更有效的camellia型方案，指出如果每一輪僅用一個隨機(jī)函數(shù)，則無論輪數(shù)如何增長，也不能使camellia型方案是偽隨機(jī)的并給出了一個如何用8個隨機(jī)函數(shù)構(gòu)造偽隨機(jī)camellia型方案的方法。
百科釋義
A pseudorandom process is a process that appears to be random but is not. Pseudorandom sequences typically exhibit statistical randomness while being generated by an entirely deterministic causal process.
