更高的保密性 meaning in English

greater security

The proposed method only needs to nansfer a scalar signal and provides higher security due to the use of hypemhaos
提出的扩频保密通信方法不仅只需传递一个标量信号，而且由于采用了超混沌系统，所设计的扩频通信系统具有更高的保密性。
In the part of voice encryption , spatiotemporal chaotic system ( ocoml model ) and lfsr are used to generate multidimensional pseudo - random sequence . this sequence has a longer period , better randomicity , passing the verification of fips 140 - 2 security requirements . using the key stream generated by it to encrypt the voice gets a better security
在语音加密方面,本文利用时空混沌系统(单向耦合映象格子模型)与线性移位寄存器产生了高维的伪随机序列,该序列周期很长,具有更强的随机性,通过了fips140 - 2的安全性能验证,利用其作为密钥流对语音信号进行加密,获得了更高的保密性。
