DES是Data Encryption stAndard(數(shù)據(jù)加密標準)的縮寫。它是由IBM公司研制的一種加密算法,美國國家標準局于1977年公布把它作為非機要部門使用的數(shù)據(jù)加密標準;它是一個分組加密算法,他以64位為分組對數(shù)據(jù)加密。同時DES也是一個對稱算法:加密和解密用的是同一個算法。它的密匙長度是56位(因為每個第8 位都用作奇偶校驗),密匙可以是任意的56位的數(shù),而且可以任意時候改變.

SHA-1(Secure Hash Algorithm)是美國國家標準局(National Institute of stAndard and Technology NIST)為了配合數(shù)位簽章演算法(Digital Signature Algorithm DSA)的使用所發(fā)布的聯(lián)邦資訊處理標準-FIPS PUB 180-1(Federal Information Processing stAndard Publication 180-1),而SHA-1 則是SHA-1 (FIPS180)的改良版,現(xiàn)今與MD5 皆廣被使用拿來做密碼驗證功能.其設(shè)計的方法是根據(jù)MD4,來對輸入的資料訊息(Message)產(chǎn)生出一個160 位元的訊息摘要(Digest) ,對於資料安全性提供了有效的保障.

This manual describes Freescale’s IEEE™ 802.15.4 stAndard compliant MAC/PHY software. The Freescale 802.15.4 MAC/PHY software is designed for use with the Freescale MC1319x and MC1320x, family of short range, low power, 2.4 GHz Industrial, Scientific, and Medical (ISM) band transceivers, designed for use with the HCS08 Family of MCUs. The MAC/PHY software also works with the MC1321x family of short range, low power, 2.4 GHz ISM band transceivers that incorporate a low power 2.4 GHz radio frequency transceiver and an 8-bit microcontroller into a single LGA package. Throughout this manual, the term transceiver refers to either the MC1319x, MC1320x, or the internal counterpart inside the MC1321x System in a Package (SiP).
