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.

摘要: A Revest, Shamir and Adleman (RSA) signature method includes: creating an initial hidden value using a private key and an RSA modular; converting a message to a hidden message by blinding the message using the initial hidden value and the RSA modular; obtaining a result value by performing double exponentiation on the hidden message, the initial hidden value, the RSA modular and the private key; and recovering a signature value using the result value. The RSA signature method further includes updating the initial hidden value with a new hidden value after the recovering.

摘要: Provided are a method for passive radio frequency identification (RFID) security according to a security mode. An RFID tag transmits its own current security mode to a reader and the reader drives a security protocol depending on the current security mode of the RFID tag. Also, the reader grasps the ability of the tag and then the reader drive a protocol suitable for the ability through the security mode.

摘要: An exemplary embodiment of the present invention provides a method and an apparatus for minimizing a difference in data path between elliptic curve point addition and elliptic curve point doubling. An elliptic curve encryption method includes a first operation step of performing point addition for two points when two points on an elliptic curve are different from each other, and a second operation step of performing point doubling for any one point when two points on the elliptic curve are the same, wherein inverse multiplication processes and multiplication processes of the first operation step and the second operation step have the same path delay.
