摘要： Apparatus for testing a random number generator includes a random number generating unit that generates and outputs random numbers, and a switching unit that receives the random numbers from the random number generating unit and selectively transmits the random numbers in response to a switching control signal. A test unit performs a basic test on the random numbers to determine whether the transmitted random numbers are within a statistical range, controls the generation of random numbers according to a result of the basic test, and outputs the switching control signal based on whether a test suite is finished. Methods include performing a basic test on generated random numbers to determine whether the random numbers are within a statistical range, controlling the generation of random numbers in response to a result of the basic test and whether the basic test is finished, determining upon completion of the basic test if a test suite is finished, and if the test suite is finished, outputting the random numbers as final random numbers.

摘要： A method of countering side-channel attacks on an elliptic curve cryptosystem (ECC) is provided. The method comprises extending a definition field of an elliptic curve of the ECC to an extension ring in a first field; generating a temporary ciphertext in the extension ring and countering attacks on the ECC; and generating a final ciphertext for the first field if a fault injection attack on the ECC is not detected. The countering of attacks on the ECC may comprise countering a power attack on the ECC. Checking if there is a fault injection attack on the ECC may be performed by determining if the temporary ciphertext satisfies a second elliptic curve equation. The fault detection algorithms takes place in a small subring of the extension ring, not in the original field, to minimize the computational overhead. The method can improve the stability of the ECC and reduce computational overhead of the ECC.

摘要： A method and system for encrypting input data may include receiving an input point and a randomness rate and generating a random selection value and a random position value from the randomness rate. At least one of the input point and points encrypted by performing elliptic curve (EC) operation over a plurality of rounds may be randomly selected based on the randomness rate and the random position value. The selected point may be converted to a point representation directed by the random selection value. A finally encrypted output point may be generated by performing the EC operation over a plurality of rounds based on the input point and a secret key.
