摘要： A method of per-packet keying for encrypting and decrypting data transferred between two or more parties, each party having knowledge of a shared key that allows a per-packet key to differ for each packet is provided. Avoiding the use of a static session key during encryption offers several advantages over existing encryption methods. For example, rejecting packets received with duplicate sequence numbers, or sequence numbers that are beyond a specified deviation range mitigates Replay Attacks.
摘要翻译：提供了一种用于加密和解密在两个或多个方之间传送的数据的每分组密钥的方法，每个方面具有允许每个分组密钥对每个分组不同的共享密钥的知识。在加密期间避免使用静态会话密钥提供了优于现有加密方法的几个优点。例如，拒绝使用重复的序列号接收的数据包，或超出指定的偏差范围的序列号可以减轻重播攻击。

摘要： The packet payload of network file data packets corresponds to read and written portions of a file (220) recognized by a file system. Individual packet payload data (222), is preferably processed into a sequence of logical access blocks (224), with each logical access block containing a corresponding portion of the packet payload data (222). The file management header (226) is virutalized for all files associated with a real mount point and locally stored by the platform effectively as part of the policy data held by the policy store. The file management header (226) includes a unique file GUID (228), security parameter index (230), and a security signature (232). The security parameter index (230) is preferably a composite of security information including an encryption key identifier (key) (234), a security options array (236), and file related information (238). The logical access blocks (224) received in the packet payload data are processed (202) to apply error correction, where the error correction field (246) is present, and validate the integrity of the LAB data fields (240), including the LAB compression headers (244) if present, against the digital signature (242) values. The filed management header (226) is read, typically in advance, by the NFS/CIFS state machine process to obtain the encryption key identifier from the field (234) and compression algorithm identity, if applicable from the options index field (236).
摘要翻译：网络文件数据分组的分组有效载荷对应于由文件系统识别的文件（220）的读取和写入部分。单个分组有效载荷数据（222）优选地被处理成逻辑接入块（224）的序列，每个逻辑接入块包含分组有效载荷数据（222）的相应部分。文件管理标题（226）对于与真实安装点相关联的所有文件进行病毒化处理，并由策略存储器保存的策略数据的一部分有效地由平台本地存储。文件管理头（226）包括唯一文件GUID（228），安全参数索引（230）和安全签名（232）。安全参数索引（230）优选地是包括加密密钥标识符（密钥）（234），安全性选项阵列（236）和文件相关信息（238）的安全信息的组合。在分组有效载荷数据中接收的逻辑访问块（224）被处理（202）以应用纠错字段（246）存在的错误校正，并验证包括LAB的LAB数据字段（240）的完整性压缩标题（244）（如果存在）与数字签名（242）值相对应。通常由NFS / CIFS状态机处理读取归档管理头（226），以从字段（234）获得加密密钥标识符，并且如果可以从选项索引字段（236）应用，则读取压缩算法身份。

The forward ECMEA process decrypts text encrypted by the reverse ECMEA process and the reverse ECMEA process decrypts text encrypted by the forward ECMEA process. The forward ECMEA process employs a first transformation, an iteration of the CMEA process, and a second transformation. The reverse ECMEA process employs a first inverse transformation, an iteration of the CMEA process, and a second inverse transformation.
