Abstract
The embodiments provides a method for processing data. According to the invention, an elliptic curve with an order m which corresponds to a product of a first cofactor c and a prime number q is provided, wherein the order (q−1) of the multiplicative group of the prime number q corresponds to a product of a second cofactor I and at least two prime divisors s, . . . , s, wherein the at least two prime divisors s, . . . , sare each greater than a predetermined bound of 2; and a chosen method is applied to provided data using the provided elliptic curve for providing cryptographically transformed data. The invention enables cryptographically transformed data to be provided while simultaneously minimizing the probability of a successful attack.
