Abstract
With the progress of the times, the concept of the quantum computer has been put forward. Encryption algorithms developed based on the discrete logarithm problem are also facing more and more challenges, However, the Elliptic Curve Digital Algorithm (ECDSA) used by bitcoin is an encryption algorithm developed based on the discrete logarithm problem. Therefore, the author wants to design a method that can prevent the password from being quickly cracked by the quantum computer and can also be compatible with the original encryption algorithm system to reduce the maintenance cost of updating the encryption system. For the two points of appeal, the author thought of improving the original encryption algorithm ECDSA. In this work, secondary random encryption on cQ through the randomness of signature is performed to improve ECDSA. The improved ECDSA encryption algorithm is not an asymmetric algorithm. This is a combination of two encryption algorithms. The combination of asymmetric and symmetric algorithms makes it difficult for quantum computers to crack. If the attacker does not know which algorithm to use, he may be forced to conduct violent attacks, which greatly increases the difficulty of cracking the original algorithm. At present, the author has realized the improvement of ECDSA, and can re-encrypt the original asymmetric ECDSA encryption algorithm so that it does not belong to the asymmetric algorithm. In this way, the security of the huge cryptocurrency market can be further guaranteed, and the algorithm can be greatly compatible with the cryptocurrency system using ECDSA as the encryption algorithm.
