In this study, the concept of Output Frequency Response Functions (OFRFs) is applied to represent the transmissibility of nonlinear isolators in frequency domain. With the OFRFs estimated from numerical simulation responses, an explicit analytical relationship between the transmissibility and the nonlinear characteristic parameters is derived for a wide class of nonlinear isolators that have nonlinear anti-symmetric damping characteristics and a comprehensive pattern about how the nonlinear damping characteristic parameters might affect the force and displacement transmissibility is built for the vibration isolators. The results reveal that it is reasonable to analyze the force and displacement transmissibility of the nonlinear isolators by simply investigating the fundamental harmonic components of the force and displacement outputs of the nonlinear isolators, and the introduction of a nonlinear anti-symmetric damping into vibration isolators can significantly suppress both the force and displacement transmissibility over the resonant frequency region, but has almost no effect on the transmissibility at non-resonant regions. These conclusions are of significant importance in the analysis and design of the nonlinear vibration isolators with nonlinear anti-symmetric damping.

由于CBC-MAC模式不可并行处理,提出了一种基于双重分组的并行认证模式(PKCB)。PKCB模式同并行认证模式PMAC相比,安全性和速率都有显著提高,PKCB认证模式与CTR(计数器)加密模式结合可构成分组密码算法的一种全工作模式。在此基础上提出了一种基于密钥计数的并行认证模式(KCTR-MAC)。KCTR-MAC模式安全性比PMAC模式高得多,而速率未降低,KCTR-MAC认证模式和CTR加密模式结合也可构成分组密码算法的一种全工作模式(2CTR),2CTR模式的综合性能不亚于标准模式CCM(CTR with CBC-MAC),是一种安全快速的实用模式。
