遺傳算法(Genetic Algorithm,GA)是一種抽象于生物進化過程的基于自然選擇和生物遺傳機制的優化技術. 遺傳算法的基本原理 在遺傳算法的執行過程中,每一代有許多不同的種群個體(染色體 )同時存在。這些染色體中哪個保留(生存)、哪個淘汰(死亡),是根據 它們對環境的適應能力來決定的,適應性強的有更多的機會保留下來 。適應性強弱是通過計算適應性函數f(x)的值來判別的,這個值稱為適應值。適應值函數f(x)的構成與目標函數有密切關系,往往是目標函數的變種。

An optimal neuron evolution algorithm for the restoration of linearly distorted images is presented in this paper. The proposed algorithm is motivated by the symmetric positive-definite quadratic programming structure inherent in restoration. Theoretical analysis and experimental results show that the algorithm not only significantly increases the convergence rate of processing, hut also produces good restoration results. In addition, the algorithm provides a genuine parallel processing structure which ensures computationally feasible spatial domain image restoration

This is the source code for encryption using the latest AES algorithm. AES algorithm is also called Rijndael algorithm. AES algorithm is recommended for non-classified use by the National Institute of Standards and Technology(NIST), USA. Now-a-days AES is being used for almost all encryption applications all around the world.

Digital Signature Algorithm (DSA)是Schnorr和ElGamal簽名算法的變種,被美國NIST作為DSS(DigitalSignature Standard)。算法中應用了下述參數: p:L bits長的素數。L是64的倍數,范圍是512到1024; q:p - 1的160bits的素因子; g:g = h^((p-1)/q) mod p,h滿足h < p - 1, h^((p-1)/q) mod p > 1; x:x < q,x為私鑰 ; y:y = g^x mod p ,( p, q, g, y )為公鑰; H( x ):One-Way Hash函數。DSS中選用SHA( Secure Hash Algorithm )。 p, q, g可由一組用戶共享,但在實際應用中,使用公共模數可能會帶來一定的威脅。簽名及驗證協議如下: 1. P產生隨機數k,k < q; 2. P計算 r = ( g^k mod p ) mod q s = ( k^(-1) (H(m) + xr)) mod q 簽名結果是( m, r, s )。 3. 驗證時計算 w = s^(-1)mod q u1 = ( H( m ) * w ) mod q u2 = ( r * w ) mod q v = (( g^u1 * y^u2 ) mod p ) mod q 若v = r,則認為簽名有效。 DSA是基于整數有限域離散對數難題的,其安全性與RSA相比差不多。DSA的一個重要特點是兩個素數公開,這樣,當使用別人的p和q時,即使不知道私鑰,你也能確認它們是否是隨機產生的,還是作了手腳。RSA算法卻作不到。
