Cellular Authentication for Mobile and Internet Services introduces the reader into the field of secure communication for mobile applications, including secure web browsing with a phone or PC, Single Sign-On (SSO), mobile broadcast content protection, secure location services, etc. The book discusses the Generic Authentication Architecture (GAA) of the mobile standardization body 3rd Generation Partnership Project (3GPP) and its American counterpart 3GPP2 in full detail and with all variants. It explains the usage of GAA by various standardization bodies and standardized applications, and also looks at a number of non-standardized ones, such as secure remote login to enterprise environment and card personalization.

iir
语音信号的iir滤波器设计,从带有噪音的信号中提取原始声音.目前,MP3播放器一般功率放大器的工作频率范围就是这个范围。但是大部分有用的和可理解的信息的频率在200到3500Hz之间。所以我们可以在这个范围间滤波,达到使声音可理解的要求。现将数字滤波器的设计指标设为通带截止频率fb=600HZ,阻带频率fc=1200HZ,通带波纹Ap=1dB,阻带波纹As=40dB,要求确定H(z)。(design of the iir filter, get the original voice without noise)
