1.GSM系统的安全策略 GSM数字移动通信系统属于第二代的移动通信技术,相对于第一代模拟技术,其安全保密性大大提高。它采取了鉴权、加密、使用,IMSI(临时移动用户识别码)代替IMSI(国际移动用户识别码)来标识用户,应用跳频技术来确保系统的安全性。首先来看处于核心地位的鉴权和加密技术。
1.GSM system security strategy GSM digital mobile communication system belongs to the second generation of mobile communication technology, compared to the first generation of analog technology, greatly improving its security and confidentiality. It takes authentication, encryption, use, IMSI (Temporary Mobile Subscriber Identity) instead of IMSI (International Mobile Subscriber Identity) to identify users, and applies frequency hopping to ensure system security. First look at the core of the authentication and encryption technology.
