A Hybrid Cryptography Technique for Improving Network Security

The transmission of medical data by mobile telephony is an innovation that constitutes the m-health or more generally e-health. This telemedicine handles personal data of patients who deserve to be protected when they are transmitted via the operator or private network, so that malicious people do not have access to them. This is where cryptography comes in to secure the medical data transmitted, while preserving their confidentiality, integrity and authenticity. In this field of personal data security, public key cryptography or asymmetric cryptography is becoming increasingly prevalent, as it provides a public key to encrypt the transmitted message and a second private key, linked to the first by formal mathematics, that only the final recipient has to decrypt the message. The RSA algorithm of River and Shamir provides this asymmetric cryptography based on a public key and a private key, on two prime numbers. However, the factorization of these two prime numbers to give the variable N of RSA can be discovered by a hacker and thus make the security of medical data vulnerable. In this article, we propose a more secured RSA algorithm with n primes and offline storage of the essential parameters of the RSA algorithm. We performed a triple encryption-decryption with these n prime numbers, which made it more difficult to break the factorization of the variable N. Thus, the key generation time is longer than that of traditional RSA.

“…Moreover, these schemes also applied in different application such as email [53], short message service (SMS) [54] and cloud computing [55]. Hybrid algorithm basically provide the integration between public key cryptography and private key cryptography schemes [56][57][58][59][60][61]; between public key cryptography schemes [62] or between private key cryptography schemes [63]. Most of the schemes in Hybrid algorithm were focused on security and, security and speed because of the integration of different cryptography schemes will strengthen the security mechanism by combining the strengths of encryption of each form [58], [60], [63].…”

This paper presents several Public Key Cryptography (PKC) algorithms based on the perspective of researchers’ effort since it was invented in the last four decades. The categories of the algorithms had been analyzed which are Discrete Logarithm, Integer Factorization, Coding Theory, Elliptic Curve, Lattices, Digital Signature and Hybrid algorithms. This paper reviewed the previous schemes in different PKC algorithms. The aim of this paper is to present the comparative trends of PKC algorithms based on number of research for each algorithm in last four decades, the roadmap of PKC algorithms since they were invented and the most chosen algorithms among previous researchers. Finally, the strength and drawback of proposed schemes and algorithms also presented in this paper.

“…Only those with connectivity to the secret key are able to decrypt (or decode) the communication into plain text. Despite the fact that today's encryption techniques are virtually impregnable, encrypted communications may sometimes be broken via cryptanalysis, also known as code-breaking 1) . As the Web and other forms of digital communication become more popular, digital security has become more important.…”

Cryptography is defined as the analysis of encryption or secretive writing of information with the use of mathematical & logical concepts in order to prevent data from being compromised. Because of the growing security issues around Internet of Things (IoT) & artificial intelligence (AI) based applications, this method has gained in significance in computer technologies for banking & healthcare systems, transportation, as well as other implementations. Although each cryptographic strategy is designed to have its own unique strength, the application of a single cryptographic strategy into a systems has certain drawbacks, as will be discussed below. For example, the symmetric key encryption approach is a cost-effective way of protecting information that does not sacrifice security in the process. The distribution of the private key, on the other hand, is a significant issue. The asymmetrical method, on either side, overcomes the problem of private key transmission; nevertheless, the independent approach is slower and uses more computer resources as comparing to symmetric encryption. While a hash function, on the other hand, produces a distinctive & fixed-length signatures for a communication in order to ensure information security, the technique is just a one-way function that is not possible to reverse. As an option to addressing the security flaws of individual cryptographic schemes, the inclusion of many cryptographic schemes, also known as the hybridization approach, is being suggested, which has the advantage of increasing the efficiency of information security while also discussing the problem of key transfer. Existing IoT & AI domains that have adopted hybrid methods have been recognized, and a study has been carried out as per classification of the domain under consideration. The security of the networks and the data sent over the network is a top priority for network providers or network operators. As a result, cryptographic methods are used to protect the data throughout the data exchange process and during different interactions. Traditional cryptographic methods, on either side, are well-known, because hackers are aware of the answer to the problem. As a result, a fresh type of cryptographic method is needed, one that increases the security & complexities of the data encryption while maintaining its simplicity. An innovative hybrid cryptographic approach for enhancing data security throughout networks transmission is presented in this article, and the consequences of its implementation and evaluation are discussed. Throughout a comparative performance study, the suggested cryptographic method was able to identify the most efficient & enhanced encrypted message.
