Abstract: A method for a key establishment in RFID system using an adaptive Q anti-collision algorithm, the method comprising:generating group key between a reader and a number of tags using values of Q that are changed under the adaptive Q anti-collision algorithm; and creating session keys between the reader and the tags using unique IDs of the respective tags.

Abstract translation: 一种使用自适应Q反冲突算法在RFID系统中建立密钥的方法，所述方法包括：使用在自适应Q抗冲突算法下改变的Q值，在读取器和多个标签之间生成组密钥; 以及使用相应标签的唯一ID在读取器和标签之间创建会话密钥。

Abstract: Provided is a white-box cryptography method and apparatus for preventing side channel analysis. An input plain text is encrypted and output according to white-box cryptography and, in this case, the value output according to the encryption includes a first value corresponding to a value obtained by masking an intermediate value obtained by encrypting the plain text with a mask and a second value corresponding to the mask.
