Abstract: PURPOSE: A subtraction operation device for a Montgomery inverse algorithm and a method thereof are provided to perform a complementary operation and an add operation based on two variables, thereby comparing and operating sizes at the same time. CONSTITUTION: A comparison operation unit (110) compares the sizes of variable U and variable V. A subtraction operation unit (120) operates a difference value of the variable U and the variable V by performing an add operation with the complement of the bit values for the variable U and the variable V. The comparison operation unit compares the sizes of the variable U and the variable V by considering the most significant bit value of a reference value. When the most significant bit value is 1, the comparison operation unit determines that the variable U is bigger than the variable V.

Abstract: A key setting method using a bivariate polynomial in a sensor network is provided to solve the security vulnerability when setting up a key, thereby making the efficient communication possible as enhancing the security of the sensor network. For the cluster-based key distribution, a sensor network is divided by a cluster unit and a bivariate polynomial which is previously distributed from a setup server is distributed to a cluster header(S204). The bivariate polynomial generates a polynomial. One or more sensor nodes are arranged in a cluster area(S206). The cluster header selects partial information and random number of the bivariate polynomial, and then distributes the selected result to the sensor nodes within the cluster(S208). When the key distribution is completed, a pairwise key is set up based on the bivariate polynomial(S212).
