Query: Dragon Crypto -- An Innovative Cryptosystem   In recent years cyber-attacks are continuously developing. This means that
hackers can find their way around the traditional cryptosystems. This calls for
new and more secure cryptosystems to take their place. This paper outlines a
new cryptosystem based on the dragon curve fractal. The security level of this
scheme is based on multiple private keys, that are crucial for effective
encryption and decryption of data. This paper discusses, how core concepts
emerging from fractal geometry can be used as a trapdoor function for this
cryptosystem.
