编码的

The method for encoding a position interpolator includes generating key data and key value data to be encoded by extracting, from a first animation path constituted by the position interpolator, a minimum number of break points, which can bring about an error of no greater than a predetermined allowable error limit between the first animation path and a second animation to be generated by the extracted break points, encoding the key data generated in step, and encoding the key value data generated in step.

用于对位置内插器进行编码的方法包括：通过从由位置内插器构成的第一动画路径中提取最小数量的断点，生成将被编码的密钥数据和密钥值数据，这些断点可以在第一动画路径和将由所提取的断点生成的第二动画路径之间引起不大于预定的可允许误差极限的误差；对在步骤中生成的密钥数据进行编码；以及对在步骤中生成的密钥值数据进行编码。

But for different specialties people gave different models for secure network coding. For instance, J P Vilela introduced light weight secure network coding, and K Bhattad introduced weakly secure network coding. When considering the practical secure network, we must think over the network coding that resists active attack, that is to say resists Byzantine attack. In this paper we also introduce such kind of network coding.
