At the same time, key school system has formed " education repulsion " to rural area students. 同时,重点学校制度对于农村学生形成了教育排斥,使农村学生未进入高中阶段之前,已经被学校教育淘汰。
At the same time achieving some key technologies of the system are analyzed and discussed. 同时对实现该系统的若干关键技术进行了分析和探讨。
At the same time designed and realized secret key producing system, through the especially arithmetic, make the serial number of secret key is more close to random serial number. 同时设计并实现安全的随机密钥产生系统,通过特定算法,使密钥序列更接近随机序列。
TD-HSPA + is based on TD-SCDMA, and at the same time introduces other key technologies to improve the system performance. In the physical layer, MIMO and high order modulation are introduced in TD-HSPA +. TD-HSPA+以TD-SCDMA技术为基础,同时引入其他关键技术提升系统的整体性能;其中在物理层,TD-HSPA+引入了MIMO和高阶调制技术。
At the same time a Rabin-type crypto algorithm based key management system is proposed. Then three RFID authentication schemes based on computing-commission signature are proposed to implement the mutual authentication between readers and tags. 论文基于Rabin型密码算法提出了适合RFID认证的密钥管理机制,并以代理计算签名为基础,给出了三个RFID认证方案,实现了标签与读卡器间的双向认证。
