File encryption and decryption key is updated dynamically, alternating convergence of old and new key is valid, just download the key material, key updates without user involvement. 文件加解密密钥动态更新,新老密钥有效交替衔接,只需用户下载密钥材料,密钥更新不必用户参与。
To encrypt file data, an encryption key password must be selected, which Tivoli Storage Manager uses to generate the encryption key for encrypting and decrypting the file data. 为加密文件数据,必须选择一个加密密钥口令,TivoliStorageManager使用它来生成加密密钥,以加密和解密文件数据。
Based on a selected chaos function that applied to video file encryption, an ideal key generator has been designed. ( 3 ) Designing a symmetrical MPEG encryption scheme that is based on composite chaos function system. 根据视频层级结构设计出密钥同步方案,选取适用于视频文件加密的混沌函数,并在此基础上构建出理想的密钥发生器。
The method is combined of software and hardware application, software processes file encryption, thus hardware takes charge of key management and conversation key encryption. 该方案采用软硬件结合的原则,由软件进行文件加密,硬件负责密钥的管理和会话密钥的加密。
The Encrypted File System ( EFS ) is a J2 filesystem-level encryption through individual key stores. 加密的文件系统(EFS)是J2文件系统级别的加密(通过单独密钥存储库)。
