An eightbyte pseudorandom number used to verify that both ends of a session with cryptography have the same session cryptography key.The value is also used as input to the Data Encryption Standard (DES) algorithm to encipher or decipher data in a session with cryptography. Note: A new initial chaining value is selected for each session.; 可用于驗證加密話路的兩端是否具有相同話路密鑰的一種八字節(jié)長的偽隨機(jī)數(shù)。初始鏈 接值還用作數(shù)據(jù)加密標(biāo)準(zhǔn)(DES)算法的輸入,以加密或解密加密話路中的數(shù)據(jù)。 注: 每條話路都可選擇一個新的初始鏈接值。
