The public key used in RSA encryption is openly registered in the public system so that other users of the system can send private messages, and the registrant of the public key has his or her own private key. The RSA authentication scheme is vulnerable to so-called 'chosen cryptogram attack'. This kind of attack can be applied to authentication of unpredictable messages only, the forger is forced to select cryptograms at random. The only known cryptosystem which can be adapted for both authentication and secrecy at the same time is the RSA system. The key to guaranteeing personal information in a public key cryptography system is that it is extremely difficult to derive a private key for decryption from a public key. In this paper, public and private keys are designed so that messages can be transmitted and received safely using the RSA algorithm exposed to various attacks. The proposed method shows relatively good performance in key generation, confidential data is very secure and reliable, and the proposed algorithm increases the randomness of the key used. This method provides more security due to random key generation and is more economical to develop compared to other public key encryption algorithms, and encryption algorithms consume significant amounts of computing resources such as CPU time, memory and battery power. However, this could be improved in the future by making this method compatible for encrypting multimedia data that must be transmitted securely over an unsecured channel.
