1. Linux内核支持哪些加密算法 ? 内核支持的加密算法非常多,包含: 对称加密算法.如AES,3DES. 对称password体制的发展趋势将以分组password为重点. 分组password算法通常由密钥扩展算法和加密(解密)算法两部分组成.密钥扩展算法将b字节用户主密钥扩展成r个子密钥. 加密算法由一个password学上的弱函数f与r个子密钥迭代r次组成.混乱和密钥扩散是分组password算法设计的基本原则. 抵御已知明文的差分和线性攻击,可变长密钥和分组是该体制的设计要点. A…

Linux内核作用: The Linux kernel is the heart of the operating system. It is the layer between the user who works with Linux from a shell environment and the hardware that is available in the computer on which the user is working. The kernel is doing so b…

Because there are numerous revisions and releases of the Linux kernel and new ones are developed at frequent intervals, it is important to have a system for clearly identifying them. A kernel is a program that constitutes the central core of a comput…
