    • Various embodiments are directed toward compressing and/or decompressing data communicated between one or more network devices (e.g., codec operations). In particular, embodiments are directed towards improving codec performance by seeding the computation workspace that may be used by various codec processors. The seeding data may be determined based on at least one characteristic of a particular codec and the characteristics of data that may be processed by the codec processor. Also, the codec processor may be employed to generate data for the codec workspace based on the determined seeding data. Workspace data may be generated by processing the seeding data with the same codec processor that is used for normal codec operations. The workspace generated from the seeding data may be stored for future use, such as, when a matched data stream arrives.
    • 各种实施例旨在压缩和/或解压缩在一个或多个网络设备之间传送的数据(例如,编解码器操作)。 具体地,实施例旨在通过播种可由各种编解码器处理器使用的计算工作空间来提高编解码器性能。 可以基于特定编解码器的至少一个特性和可由编解码器处理器处理的数据的特性来确定播种数据。 此外,编解码器处理器可以用于基于所确定的播种数据来生成用于编解码器工作空间的数据。 可以通过使用用于正常编解码器操作的相同编解码器处理器处理播种数据来生成工作空间数据。 从播种数据生成的工作空间可以存储以供将来使用,例如当匹配的数据流到达时。

    • Embodiments compress and encrypt data in a single pass to reduce inefficiencies that occur from compression and encrypting data separately. Typically, compression and encryption are implemented in separate functional units. This has a few disadvantages: 1) encryption cannot make use of compression state to further secure the message, 2) processed data is read and written twice, 3) additional space, time, and resources are consumed, and 4) it is more prone to potential cipher-attacks since the encryption stage is independent from compression. Embodiments overcome these disadvantages by structuring these operations so that both compression and encryption is executed within the same processing loop. Thus: 1) encryption is stronger due to the dependence on the compression state, 2) I/O buffers are accessed only once reducing overhead, 3) system footprint is reduced, and 4) cipher analysis is more complex since the decryption process cannot be separated from the decompression process.
    • 实施例在单次传递中压缩和加密数据,以降低压缩和分开加密数据所产生的低效率。 通常,压缩和加密在单独的功能单元中实现。 这有一些缺点:1)加密不能利用压缩状态来进一步保护消息,2)处理的数据被读取和写入两次,3)消耗额外的空间,时间和资源,4)更容易 由于加密阶段与压缩无关,因此可能发生密码攻击。 实施例通过构造这些操作来克服这些缺点,以便在相同的处理循环内执行压缩和加密。 因此:1)由于依赖于压缩状态,加密更加强大,2)I / O缓冲区只能减少一次开销,3)系统占用减少,4)密码分析更复杂,因为解密过程不能 与减压过程分开。
