阅读说明：本技术 用于加密和更新虚拟盘的方法 (Method for encrypting and updating virtual disk ) 是由 J·J·卡鲁埃纳 于 2020-03-30 设计创作，主要内容包括：一种用于加密虚拟盘的方法包括为虚拟盘的第一版本的每个页生成散列值。每个页使用唯一初始化向量(IV)进行加密。每个唯一IV和每个所生成散列值随后被存储在明文散列数据库中,该明文散列数据库将页的每个唯一IV映射到对应散列值。对于虚拟盘的第二经更新版本,为第二版本的每个页生成散列值。随后确定每个新生成的散列值是否被存储在明文散列数据库中。如果虚拟盘的第二版本的第一页的第一所生成散列值被存储在明文散列数据库中,则使用来自明文散列数据库的与第一所生成散列值相对应的唯一IV来加密这样的第一页。(A method for encrypting a virtual disk includes generating a hash value for each page of a first version of the virtual disk. Each page is encrypted using a unique Initialization Vector (IV). Each unique IV and each generated hash value is then stored in a plaintext hash database that maps each unique IV of a page to a corresponding hash value. For a second updated version of the virtual disk, a hash value is generated for each page of the second version. It is then determined whether each newly generated hash value is stored in the plaintext hash database. If a first generated hash value of a first page of a second version of the virtual disk is stored in the plaintext hash database, such first page is encrypted using a unique IV from the plaintext hash database that corresponds to the first generated hash value.)
