    • A method for transmitting key data in a wireless sensor network is provided to adjust a security level according to a security importance of the wireless sensor network by adjusting combination complexity of key data and scramble data according to the security level. A method for transmitting key data in a wireless sensor network includes the steps of dividing the key data to be transmitted into a predetermined number of blocks according to a security level(S5); dividing scramble key data having the same size with the key data and randomly generated into blocks of the same number as the key block(S7); and mixing and generating the key data block and the scramble key data block, and generating a plurality of key combination data having the same size as the key data(S9). The number of blocks of the key data and the scramble key data divided according to a security level are calculated by an equation one as follows Ks=(n)k, wherein n is a natural number. The key combination data is generated as much as the number of n.
    • 提供一种在无线传感器网络中传输密钥数据的方法,通过根据安全级别调整密钥数据的组合复杂度和加扰数据,根据无线传感器网络的安全重要性来调整安全级别。 一种用于在无线传感器网络中传输密钥数据的方法,包括以下步骤:根据安全级别将要传输的密钥数据分成预定数量的块(S5); 将与密钥数据具有相同大小的随机生成的加扰密钥数据划分成与密钥块(S7)相同数量的块; 并且混合并生成密钥数据块和加密密钥数据块,并且生成与密钥数据具有相同大小的多个密钥组合数据(S9)。 根据安全级别划分的密钥数据和加扰密钥数据的块的数量通过如下的等式1来计算:Ks =(n)k,其中n是自然数。 密钥组合数据的生成与n的数量一样多。
