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.

Spearman's rank relationship coefficient is a nonparametric (dispersion free) rank measurement. Spearman's coefficient is not a measure of the direct relationship between two factors, as a few analysts proclaim. Pearson's relationship coefficient is the covariance of the two factors separated by the result of their standard deviations. The possibility of the paper is to look at the estimations of Pearson's concrete compressive strength coefficient and Spearman's rank relationship coefficient and in addition their factual hugeness for various arrangements of information depicting provincial records of the financial advancement. In this, the Spearman correlation coefficient is based on the ranked values for each variable rather than the raw data. Spearman correlation is often used to evaluate relationships involving ordinal variables. The Pearson and Spearman's method is compared with the rank coefficient in the concrete compressive strength. © 2017 IEEE.

Now-a-days, in the medical field, prescribing a medicine for a patient without mentioning its brand name is a tedious job. But it can be made possible, when both the parties (physician and pharmacist) are adapting well and standardized methodology. Our aim is to suggest an idea to make this process easy to understand and light to use. Based on the types of common diseases, the medicinal prescription lists can be categorized with relevant medicinal blocks. If a physician prescribes the medicine through this standardized predefined scheme, then the system will generate a unique number using Grace Code Cryptography and Linear RSA algorithms. The unique number will be given to the patient in the prescription sheet. Through this unique number, the pharmacist can get back the medical unit which is intended for a particular patient with the help of the same algorithms and using the standardized predefined scheme as it is a general template, and he delivers the medicine. So the patient will be given the prescribed medicine without specifying the brand name at any stage. © 2016 IEEE.

Analyzing the strength of Pell’s RSA

This research based paper’s focus is to develop a spanning tree approach for error detection and correction in the data being received at the receiver’s portal. The main objective of this paper is to ease the error detection process inculcated in the data received from a reliable source. The main contribution of this paper is the development of error detection algorithm which is integrated on Spanning Tree approach. Spanning tree (say T) is a tree composed of all the vertices and some edges of a connected, undirected graph(say G) where in every vertex lies in the tree but no cycles(or loops) are formed. The technique being used in the paper will help find the errors that are usually encountered during the transmission of the data unit. The traditional correction techniques are being coupled with the newly proposed method to attain the error-free data unit. © 2016, International Journal of Pharmacy and Technology.

In cryptography, encryption is the process of transforming information (referred to as plaintext) using an algorithm (called a cipher) to make it undetectable to anyone except those possessing special knowledge, usually referred to as a secret key. The result of the process is encrypted information (referred to as cipher text). The reverse process is to make the encrypted information readable again, is referred to as decryption (i.e., to make it unencrypted).Encryption can protect the confidentiality of messages by itself, but other techniques are still needed to protect the integrity and authenticity of a message. In this paper we are going to implement BASE128 encoding technique to convert 8-bit character to 7-bit character so that they can be transferred over the internet.Base128 encoding standard can be used by almost all the email clients to encode the files which are sent as attachments by Multipurpose Internet Mail Extension(MIME). © 2016, International Journal of Pharmacy and Technology.

In the modern world, computer system plays a vital role based on type of applications. Hence, there is a need to research and develop such system to improve its performance. In the field of computer architecture, cache address mapping acts between main memory and cache. Moreover, based on the internal or external request of the system, a bunch of words can be loaded onto cache memory. Due to the volatility nature of internal memory, the cache history gets abscond once the system is deactivated. However, the processor performance is based on various factors such as cache size and hit, write policy, type of cache mapping technique, CPU speed, front side bus, and depth of cache level. For cache, a number of standard cache addresses mapping are available. Among these, some of the well known techniques are set associative, fully associative and direct mapping technique. This paper reviews on non-linear cache address system in quadratic and cubic set associative cache address mapping. The standard set associative mapping is remapped with quadratic set associative technique for to secure the data in a non sequential fashion by having the standard mapping execution time. This work can also be applied to design the cache chip enhancement and improvement. © 2016, International Journal of Pharmacy and Technology. All Rights Reserved.

Public key cryptography (PKC) plays the phenomenal role in asymmetric based security applications such as E-mail, File sharing, Cloud storage, etc. As like in std. RSAet. al [11], Dual RSA scheme et. al [6] has public code (E,N1,N2) and private code (d,r1,r2,s1,s2). In this paper Trivial RSA is realized with (E,N1,N2,N3) and (d,r1,r2,r3,s1,s2,s3) codes which essentially satisfies the condition ED =1+z1ϕN1=1+z2ϕN2=1+z3ϕN3. Here a1,a2,b1,b2interrelated keys are used to generate primes r1, r2,r3,s1, s2, s3which takes z2=b1and z3=b2. The strength of keys are tested using lattice constraint nd&lt; n0.33. © 2016, International Journal of Pharmacy and Technology. All rights reserved.

Review on the memory efficient RSA variants

Accidents in railway lines include collision with snags, derailment and human losses due to movements of trains. Railway transportation is usually very safe for passengers, although railway accidents and train derailment still happen. To solve this problem, a railway security system is proposed in this article. Here Ad hoc Wireless Networks are employed, but implementation of these systems poses problems due to the length of railway lines. On the other hand use of Ad hoc Wireless Network promises a very interesting and practical option. With recent advances in wireless communication and in electronics, there has been a reduction in the price, power, and size of sensor nodes. There sensors include a microprocessor, a multi-byte RAM, a short-range, short-wave radio transmitter, and a small power source (like a battery).The main technique and the major aim of this system is to develop a new solution, based on a Adhoc Wireless Networks with the use of WiMAX(Worldwide Interoperability for Microwave Access) for the problems faced in railway lines. The purpose in studying railway lines includes finding new methods to reduce the rate of accidents. © Research India Publications.

Accident avoidance in railway tracks using adhoc wireless networks

Most of the researchers and scientists are striving towards the enhancement of Genetic Algorithm (GA) which is under the field of Bio-Informatics. In general a Genetic Algorithm is solved by using Crossover and Mutation method. Here Crossover refers to a random shifting of a child in order to make new tours and Mutation adjust the Crossover. However, a Genetic Algorithm is efficient in itself, yet there are two problems that can be further optimized to get better results. Those problems are: During the encoding of tour if population is less, it may result in identical solutions, which is invalid. To solve the first problem we need to increase the population size. But on doing so, the time complexity will rise exponentially. In this paper I am proposing a modified Genetic Algorithm which essentially aims at eliminating the above stated problems. Furthermore, I will try to demonstrate this solution by an application that might be used by a detection based database. © Research India Publications.

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 &amp; 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. © 2013 IEEE.
