According to the National Institute of Standard and Technology (NIST), the security level of RSA is safe when it is N-bit modulus ≥2048 bits. Because of this, the processing time to generate asymmetric keys also increases. Taking this into account, an efficient and non-shareable Public Key Exponent Secure Scheme (ENPKESS) is proposed by using a non-linear Diophantine equation to have high security against side-channel attacks like timing attacks. This scheme has three-stage of encryption and two-stage of decryption, whereas other schemes like ESR and RSA has one level in encryption and decryption. Due to this, extraction of the secret key is extremely hard to determine from our public exponents α,R,N. Our methodology is well suited for secure cloud computing environments used in the Internet of Things (IoT). Here we have also applied the Knapsack method to encrypt our ENPKESS keys to enrich high security in cloud systems. We show a strong performance evaluation on standard RSA, Enhanced and Secured RSA Key Generation Scheme (ESRKGS), and ENPKESS on its key generation, encryption and decryption by varying the N-bit moduli size up to 10K bits. From the overall result, ENPKESS consumes 89% of standard RSA and 27% of ESRKGS. © 2019 Elsevier B.V.

An efficient public key secure scheme for cloud and IoT security

Currently, a multimedia revolution of medical data in health information becomes part of our computing environment. However, the interchange of medical information is typically outsourced by third parties, which may affect the disclosure of confidentiality. To address this issue, we address high security and confidentiality through our proposed CHAN-PKC cryptomata. The proposed scheme uses a Diophantine equation to have the three stage of decryption for high security, but ESRKGS and RSA has one level of decryption. The results show that the proposed cryptomata has efficient encryption and decryption time when compared to the existing systems. At 10 K-bit moduli of key generation, CHAN-PKC consumes only 0.65 times of RSA, but ESRKGS takes 1.83 times of RSA. The timing similarity shows that both CHAN-PKC and RSA has a 100% correlation, but ESRKGS has only 90%. Hence our CHAN scheme is robust against side channel and also has a large key space than RSA. The security analysis confirms that our CHAN-PKC is very fast, secure against brute force and side channel attacks; therefore, it is feasible for real-time applications. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.

Modelling a side channel resistant CHAN-PKC cryptomata for medical data security

A new variant of RSA has been proposed called Memory Efficient Multi Key (MEMK) generation scheme. For sensitive data, our scheme will aid in exchanging the information between cloud to IoT and IoT to IoT devices. When cryptography belongs to the asymmetric type, then it has public and private keys. For memory efficiency, our scheme reuses the RSA scheme with a Diophantine form of the nonlinear equation. Moreover, our scheme performance comparatively performs well and this mainly due to the use of RSA public key alone. Due to this, our MEMK does not require multiplicative inverse function or Extended Euclid's algorithm. Finally, we have made an experimental result on various phases of MEMK PKC such as key generation, encryption, and decryption by varying the N-bit modulo bits from 1K to 10K. © 2017 IEEE.

Memory efficient multi key (MEMK) generation scheme for secure transportation of sensitive data over cloud and IoT devices

IoT devices are everywhere. Shortly, every 'thing' is going to be connected and interact with each other. What are these things? They can be your microwaves, heaters, air conditioners or even your refrigerators. It assessed that there would be 50 billion connected IoT devices by 2020 which is about 7 IoT gadgets for every individual on the planet. IoT devices are low powered devices which have a minimal amount of processing capabilities. With ever increasing number of IoT devices, there is a subsequent need for secure communication among them. In this paper, we aim to propose an encryption algorithm used for secure communication by taking into account the limitations of IoT devices. © 2017 IEEE.
