Selecting random sequence N as the initialization vector, and calculated. 选取随机序列N作为初始向量,计算。
I then extract the initialization vector ( IV ) into a byte array, block encrypt the clear data, and prefix the IV bytes to the encrypted data bytes. 随后我将初始向量(IV)抽取到字节数组,对明文数据进行块加密,并将IV字节置于加密的数据字节之前。
The key and the initialization vector are encrypted with the public key of the user to protect its confidentiality. 密钥和初始向量用用户的公钥加密以保护它的机密性;
The Blowfish symmetric-key encryption algorithm protects the confidentiality of the files, the key and the initialization vector of a file are auto generated by the file system after the file being created. 文件的机密性由Blowfish对称密钥加密算法保护,文件在创建后由系统自动生成Blowfish密钥和初始向量。
In order to overcome the problems of traditional snake associated with poor convergence to boundary concavities and sensitive initialization, gradient vector flow based on deformable models is presented to segment tumor region. 为了克服传统的蛇形算法不能收敛于边缘凹陷处以及对蛇的初始化过于敏感的缺点,本文提出用基于可变形模型的梯度矢量流方法提取乳腺X光片中的肿瘤区域。
