Yuan said: "I would rather go to Xiang River flows buried in the belly of the fish; security can Haohao of white, and almost dust mask secular?" 屈原道:“宁赴湘流葬于江鱼之腹中;安能以皓皓之白,而蒙世俗之尘埃乎?”
Security can Haohao of white, and almost dust mask secular? 安能以皓皓之白,而蒙世俗之尘埃乎?
Objective To evaluate the feasibility and security of laryngeal mask airway ( LMA) during general anesthesia for the operation of endovascular embolization in intracranial aneurysms. 目的探讨喉罩置入通气(LMA)在颅内动脉瘤血管内介入治疗术麻醉中应用的可行性和安全性。
After extension, new security properties of users, security label and audit mask, are added to the IA system, in order to support the mandatary access control ( MAC) and audit system under the Secure OS. 扩展后的标识鉴别机制增加了新的用户安全属性,即安全标签和审计掩码,以增加对安全操作系统下强制存取访问控制和审计机制的支持。
A real-value encryption and decryption method is proposed for the optical image security system. A full-phase image to be encrypted together with a random phase mask is Fourier transformed and real part of the result is used as an encrypted image. 一种用于纯相位图象加密的实值编码方法,待编码的纯相位图象与一个随机相位掩膜一起作傅立叶变换,取其实部作为编码图象。
In order to improve the security of mode of operation, a masked ECB mode of operation was constructed with the Gray code to mask the plaintext. 针对电子密码本模式无法隐蔽明文数据模式因而具有很大的安全隐患这一缺点,引入Gray码对明文进行伪装,构造了一个伪装的电子密码本工作模式。
Intrusion tolerance is a rising network security technology which combines the cryptography and the fault tolerance. The concern of intrusion tolerance is not how to detect or prevent intrusion, but how to mask or restrain intrusion. 入侵容忍是一门融合密码技术和容错技术的新兴网络安全技术,其关注的不是如何检测或防御入侵,而是考虑系统在已经遭到入侵的情况下,如何有效的屏蔽或遏制入侵行为。
