In this paper, a new variant of RSA has been proposed whose key generation method is distinct with the standard RSA. Generally the RSA family of variants can be applied at the secured channel to enhance its data trust level on various applications such as E-commerce, Internet applications, etc., The boundary level of the private key has been recommended here, to raise over these variant to stay away from the possibility of getting the Small `d' value either by continuous fraction method of Wiener's attack, or by Coppersmith's lattice based method of Boneh & Durfee attack, or by retrieving the Euler's totient function value by Fermat factorization method. This paper discusses the proposal of Pell's RSA key generation and its security analyses over the standard RSA, N Prime RSA, Dual RSA. Finally the application of Pell's RSA, Blind signatures, are proposed.

Pell's RSA key generation and its security analysis

The technological advancements in the information sharing and the development of many techniques to make the information conveyance easy necessitate a protection methodology that could prevent the personal information that is transmitted from being hacked. Some of the protection methods that have emerged are the cryptography, steganography, watermarking, digital signature etc. As steganography is a popular method of transmitting the covered secret information in order to avoid hacking and the misuse due to its major attributes such as the security, capacity and the robustness. This paper puts forward cryptography incorporated steganography (CICS) to provide a highly secure steganography algorithm for the files of the multiple formats, The performance analysis of the method and the measurement of the parameters such as the PSNR and the SSIM are done to ensure the efficiency of the proffered method.

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.

We present new variants of an RSA whose key generation algorithms output two distinct RSA key pairs having the same public and private exponents. This family of variants, called dual RSA, can be used in scenarios that require two instances of RSA with the advantage of reducing the storage requirements for the keys. Two applications for dual RSA, blind signatures and authentication/secrecy, are proposed. In addition, we also provide the security analysis of dual RSA. Compared to normal RSA, the security boundary should be raised when applying dual RSA to the types of small-d, small-e, and rebalanced-RSA.
