Definitions
- the present invention relates to a cryptographic method on an elliptical curve. Such a method is based on the use of a public key algorithm, and can be applied to the generation of probabilistic digital signatures of a message and / or to a key exchange protocol and / or to an algorithm encryption of a message.
- ECDSA from the English Elliptic Curve Digital Standard Algorithm
- the parameters of the ECDSA are:
- the number t of couples (ki, Pi) stored is between 35 and 45.
- the number of iterations of the loop (niter) is fixed between 10 and 12.
- the size of the mathematical body n on which the Koblitz curve is defined is equal to 163.
- n ⁇ te r is fixed between 10 and 12 iterations.
