    摘要: An apparatus and method for protecting radio frequency identification (RFID) data in a communication between a RFID tag and a RFID reader are provided. In the apparatus and method for protecting RFID data, message header information transmitted while communicating the RFID tag and the RFID reader is used to perform an encryption operation for important data, thereby protecting the important data included in the RFID tag. In the present invention, information of the RFID tag can be protected from an illegitimate eavesdropper and an ill-intentioned and unusual message can be detected, thereby ensuring the security of a RFID system.

    摘要: An apparatus for generating a secret key generates the secret key by using information of a mobile RFID terminal, transmits the generated secret key to an RFID tag attached on an article, and decrypts a unique item identifier of the article encrypted by using the generated secret key after receiving the unique item identifier of the article encrypted by using the secret key from the RFID tag. By this configuration, it is possible to protect user's personal privacy of the mobile RFID terminal in a state where user's intervention is minimized.

    摘要: A masking addition operation apparatus for prevention of a side channel attack, includes a random value generation unit generating a first random value for a first input, second random value for a second input, and a summation random value. The masking addition operation apparatus includes an operation part performing an operation on the first and second random values, a previous carry input, and first and second masked random values generated based on the first and second random values. The masking addition operation apparatus includes a carry generator generating a carry input using a result of the operation part; and a summation bit generator generating a summation bit using the summation random value, the first and second random values, the previous carry input and the first and second masked random values.
