Improvement of indication stability of measuring signal by slip window sampling 利用滑动窗口法改善测量信号的示值稳定性
Based on the method , a tracking window method is adopted to track the target , and locate the position of target centroid by adjusting the window self - adaption 本算法采用动态窗口法,利用目标颜色的概率分布特征,锁定目标的颜色分布区域的质心,达到快速准确的跟踪效果。
The first key technique : using plain - text cipher and md5 message - digest algorithm to ensure stb and dhcp server ' s certificate and secure the stb and server ' s communications - the second key technique : using hmac algorithm to realize the safe functions - the third key technique : using ipsec to realize safe functions o those three methods " complexity increases in turn and the degree of the security increases as well which depend on the frame of the methods and the complexity of the algorithm . all theose three methods use the unique serial - number or a special slip - window to defend replay attack 主要采用三种安全方案实现:第一种:利用约定的明文密码验证机顶盒与dhcp服务器的合法身份, md5验证信息合法性:第二种:利用hmac算法验证机顶盒与服务器身份,信息合法性;第三种:利用ipsec验证机顶盒与dhcp服务器身份与信息合法性。每一种方案中皆采用包序号唯一法或者滑动窗口法保证重放攻击。此三种方案复杂度依次增加,安全度依次升高,主要取决于算法的复杂度与架构的搭建。
Operation layer is the basic core part in elliptic curve encryption system including how to calculate elliptic curve ' s stairs is a large prime or including a large prime gene to ensure elliptic curve to be safe elliptic curve ; in this article safe elliptic curve is chosen by p1363 sae algorithm . besides , how to achieve fast point multiplication will influence the performance efficiency of the whole encryption system ; in this article , for different situations , signed binary method and rolling window method are respectively applied to perform quick operation of elliptic curve ' s point multiplication 运算层是椭圆曲线密码体制实现的最基础、最核心的部分,包括如何来计算椭圆曲线的阶为大素数或含有一个大的素因子,以保证所选取的椭圆曲线为安全椭圆曲线,本文根据ieeep1363协议的sea算法实现了安全椭圆曲线的选取;另外如何实现标量乘的快速运算,将会影响整个密码系统的实现效率,本文根据不同情况对椭圆曲线的标量乘法分别采用了带符号的二进制法和滑动窗口法进行快速运算。
