Linear codes have been an interesting topic in both theory and practice for many years.In this paper.a class of linear codes with three and five weights over Fp is constructed.where p is an odd prime.Furthermore.the weight distributions of these linear codes are determined.These codes may have applications in secret sharing schemes and data storage systems.

通过对弧形筛工作原理和筛面运动状态的分析,说明弧形筛安装击打器的必要性.针对原有机械式击打器的缺点,开发了用于精煤泥弧形筛的GHQD型气动式击打器,通过林西选煤厂工业性试验说明该击打器应用于浮选入料粒度控制方面效果是良好的,提高了弧形筛的工艺指标.
近年来，侧信道分析对各类密码设备构成了严重的安全威胁。利用设备运行时产生的数据相关信息泄露，攻击者可以有效恢复出密钥，即使实现中所用的密码算法具有很好的数学性质。在目前的侧信道分析中，虽然信息泄露中包含与密码运算的中间状态相关的信息，但若无训练设备的辅助，攻击者并不能通过信息泄露来直接恢复密码运算的中间状态。为了恢复密钥，攻击者通常采用“先猜测后确定”的攻击策略，即攻击者先猜测部分密钥，根据密钥猜
