DES是Data Encryption stAndard(数据加密标准)的缩写。它是由IBM公司研制的一种加密算法,美国国家标准局于1977年公布把它作为非机要部门使用的数据加密标准;它是一个分组加密算法,他以64位为分组对数据加密。同时DES也是一个对称算法:加密和解密用的是同一个算法。它的密匙长度是56位(因为每个第8 位都用作奇偶校验),密匙可以是任意的56位的数,而且可以任意时候改变.

SHA-1(Secure Hash Algorithm)是美国国家标准局(National Institute of stAndard and Technology NIST)为了配合数位签章演算法(Digital Signature Algorithm DSA)的使用所发布的联邦资讯处理标准-FIPS PUB 180-1(Federal Information Processing stAndard Publication 180-1),而SHA-1 则是SHA-1 (FIPS180)的改良版,现今与MD5 皆广被使用拿来做密码验证功能.其设计的方法是根据MD4,来对输入的资料讯息(Message)产生出一个160 位元的讯息摘要(Digest) ,对於资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).
