The round keys are derived from the cipher key by means of the key schedule 該域可能只包含一小部分與該用戶初始登錄相關(guān)的
Authority procedure in dedicate mode checks the ms ' s validity , and if it is valid , a safe cipher key for the use of channel encrypting is given 專用模式下的鑒權(quán)過程用于網(wǎng)絡(luò)檢查ms提供的識別是否真實(shí),并給ms一個(gè)安全的密鑰。
These appliances , available from companies such as decru , neoscale , and vormetric , implement very fast encryption - they typically claim to operate at or close to " wire speed . " they also usually include sophisticated key management facilities for controlling the creation and distribution of cipher keys , cycling of keys , and disposition of keys , besides handling general data encryption Decru 、 neoscale和vormetric等公司都能提供這些器件,它們實(shí)現(xiàn)了非常快的加密通常被聲稱速度達(dá)到或接近“線速” 。它們還常常包括高級的密鑰管理設(shè)施,除了用于處理一般的數(shù)據(jù)加密外,還可用于控制密鑰的創(chuàng)建和分發(fā)、密鑰的循環(huán)和密鑰的銷毀。
You can choose different encipher algorithms according to requirement . aes is a symmetric block cipher that can process data blocks of 128 bits , using cipher keys with lengths of 128 , 192and 256 bits . because the length of block and key has been expanded , security has been enhanced Aes ( advancedencryptionstandard )是fip ( federalinformationprocessingstandardspublication )在2001年6月發(fā)布的草案,它是分組加密算法,消息分組為128bit ,有三種密鑰長度128bit 、 192bit 、 256bit ,由于分組長度和密鑰長度加長使得安全性大大的提高,它有望成為21世紀(jì)的加密標(biāo)準(zhǔn)。
