2023, The Foundation of Asymmetric Encryption: Computational Principles Behind Prime Number Factorization

Asymmetric encryption techniques have transformed secure communication by introducing a paradigm that utilizes distinct keys-a public key for encryption and a private key for decryption. At the core of these methods lie intricate computational operations, particularly involving the factorization of large prime numbers. This article delves into the computational aspects of asymmetric encryption, emphasizing algorithms like RSA and the complex calculations integral to their security within the realm of computer science. Introduction: Asymmetric encryption, a cornerstone of computer science, facilitates secure data exchange without necessitating a shared secret key. It operates on mathematically linked key pairs-a public key known to all and a private key kept confidential by the recipient. This innovative approach significantly contributes to digital security. Prime Numbers and their Computational Significance: Prime numbers, fundamental in computer science, play a pivotal role in ensuring the security of encrypted data. The robustness of asymmetric encryption stems from the computational complexity of factoring the product of two large prime numbers, forming the basis of security in algorithms like RSA. Consider two large prime numbers, p = 61 and q = 53. Their product, n = p × q = 3233, serves as the modulus for encryption and decryption operations.

In this paper the development of a software to encrypt messages with asymmetric cryptography is presented. In particular, is used the RSA (Rivest, Shamir and Adleman) algorithm to encrypt alphanumeric information. The software allows to generate different public keys from two prime numbers provided by the user, the user must then select a public-key to generate the corresponding private-key. To encrypt the information, the user must provide the public-key of the recipient as well as the message to be encrypted. The generated ciphertext can be sent through an insecure channel, so that would be very difficult to be interpreted by an intruder or attacker. At the end of the communication, the recipient can decrypt the original message if provide his/her public-key and his/her corresponding private-key.

RSA's strong cryptosystem works on the principle that there are no trivial solutions to integer factorization. Furthermore, factorization of very large semi primes cannot be done in polynomial time when it comes to the processing power of classical computers. In this paper, we present the analysis of Fermat's Last Theorem and Arnold's Theorem. Also highlighted include new techniques such as Arnold's Digitized Summation Technique (A.D.S.T.) and a top-to-bottom, bottom-to-top approach search for the prime factors. These drastically reduce the time taken to factorize large semi primes as for the case in RSA Cryptosystem.

In this paper we introduce an approach which is more secure than original RSA algorithm, which is used for digital signatures and encryption in public key cryptography. This approach eliminates the need to transfer n, the product of two random but essentially big prime numbers, in the public key due to which it becomes difficult for the intruder to guess the factors of n and hence the encrypted message remains safe from the hackers. Thus this approach provides a more secure path for transmission and reception of messages through public key cryptography.
