Paradigms of Cloud computing are gaining prevalent acceptance due to the numerous benefits they provide. These comprise cost-effectiveness, time savings and effective deployment of computing resources. However, privacy and security issues are among the major hindrances holding back the widespread adoption of this novel technology. In this context, enhancing the security of cloud computing demands the highest priority based on the popular encryption method rsa, Genetic algorithm (GA), and 3D Quick Response (QR) code using MAC address. This paper will show an approach of amplifying the security of cloud computing. Therefore, we are proposing advanced two-step security mechanism of cloud computing. Firstly, rsa is used to provide initial protection of the first stratum. rsa approaches message as input to the hash function and generated hash values is encrypted by using generated sender key. And the receiver will generate a hash code and decrypts the message using the sender's public key. Finally', The Genetic algorithms (GA) are generalized search algorithms based on the mechanics of natural genetics. GA maintains a population of individuals that represent the candidate solutions. After successful completion of Genesis, mutation and crossover GA will provide a framework to match the desired pattern. Moreover, a media access control address (MAC address) of a device is a distinctive identifier assigned to network interfaces for communications at the data link layer of a network segment. In this context, the MAC address is used to generate the 3D Quick response code for user verification. Through experiments, we affirm that the combination of GA and 3D QR Code approach with rsa for two-step security mechanism shows strong potential to heighten the security of Cloud Computing.

We measure the popularity of cryptographic libraries in large datasets of rsa public keys. We do so by improving a recently proposed method based on biases introduced by alternative implementations of prime selection in different cryptographic libraries. We extend the previous work by applying statistical inference to approximate a share of libraries matching an observed distribution of rsa keys in an inspected dataset (e.g., Internet-wide scan of TLS handshakes). The sensitivity of our method is sufficient to detect transient events such as a periodic insertion of keys from a specific library into Certificate Transparency logs and inconsistencies in archived datasets. We apply the method on keys from multiple Internet-wide scans collected in years 2010 through 2017, on Certificate Transparency logs and on separate datasets for PGP keys and SSH keys(1). The results quantify a strong dominance of OpenSSL with more than 84% TLS keys for Alexa 1M domains, steadily increasing since the first measurement. OpenSSL is even more popular for GitHub client-side SSH keys, with a share larger than 96%. Surprisingly, new certificates inserted in Certificate Transparency logs on certain days contain more than 20% keys most likely originating from Java libraries, while TLS scans contain less than 5% of such keys. Since the ground truth is not known, we compared our measurements with other estimates and simulated different scenarios to evaluate the accuracy of our method. To our best knowledge, this is the first accurate measurement of the popularity of cryptographic libraries not based on proxy information like web server fingerprinting, but directly on the number of observed unique keys.

rsa algorithm is public key algorithm using prime number and even still used today. The strength of this algorithm lies in the exponential process, and the factorial number into 2 prime numbers which until now difficult to do factoring. The rsa scheme itself adopts the block cipher scheme, where prior to encryption, the existing plaintext is divide in several block of the same length, where the plaintext and ciphertext are integers between 1 to n, where n is typically 1024 bit, and the block length itself is smaller or equal to log(n)+1 with base 2. With the combination of rsa algorithm and block chiper it is expected that the authentication of plaintext is secure. The secured message will be encrypted with rsa algorithm first and will be encrypted again using block chiper. And conversely, the chipertext will be decrypted with the block chiper first and decrypted again with the rsa algorithm. This paper suggests a combination of rsa algorithms and block chiper to secure data.

A modern power grid with smart devices, smart houses, smart meter, smart vehicle and transmission lines connected through a network constitute smart grid. Unlike the traditional structure of power grid, a smart grid provides transparency between the customer and distributor and having a property of self-healing and self-monitoring. In this paper, an integrated approach of fog and IOT is presented as a backbone for smart grid structure. Wherein the micro-grid concept is proposed with fog to extend the feature to the end users and efficient load balancing and power consumption technique are being introduced. Private data of smart meter is secured by the use of rsa algorithm at the fog server. Further, smart street light is integrated with fog server for efficient load balancing.

Aquaculture farmers and exporters usually face concerns related to data privacy and security of their farm data while using digital apps (Mobile Applications). Existing applications encrypt data by transmitting the keys over the network to achieve data security. However if this key is pilfered, there arises a risk of compromise in data security. To overcome this risk, we have proposed a method to avoid the transfer of keys over the network. In the proposed method, user's input data such as password, is hashed and encrypted and is used along with a set of random prime numbers to generate the encryption/decryption keys at both client and server end. This approach helps in adding a second layer of data security.

Existing multipath routing methods in a Wireless Sensor Networks (WSNs) have presented the effective distribution of traffic over multipath to accomplish required quality of service (QOS). But, failure of the any link in WSN affects the data transmission performance, security of data, scalability and reliability of WSN. Hence, by considering the reliability, scalability, security and congestion for the multipath in a wireless sensor network, it is necessary to design and develop a service focused multi path routing scheme which should provide high failure tolerance and effective routing scheme. This paper put forth a Secure Multipath AODV (SMAODV) protocol in which rsa algorithm is used for secure data transmission and path vacant ratio is calculated to discover the link disjoint path to destination sensor node from source sensor node from all presented paths in a network. Load balancing metrics and technique like detection of congestion, congestion notification and congestion control is used to fine tune and balance the load over multi paths. Split the data packets into multiple fragments and sent it to the destination node through multipath based on the path vacant ratio.

This paper introduces a method for distribution feeder resiliency improvement during emergency/disasters situations. Mixed integer linear programming (MILP) method solves the proposed optimization problem. Based on the DGs locations, feeder is reconfigured and looped microgrids are formed to feed most weighted loads. For secure sharing the feeder data with the distribution management system (DMS), rsa algorithm is used. rsa is one of the practical public-key cryptosystems and is widely used for secure data sharing. rsa is used to secure the date from each node to the DMS as well as the return commands from DMS to each node/switch. The microgrid formation method and the rsa algorithm are applied on the IEEE 37-node test feeder. Two microgrids are formed and an encryption example is explained to show the security process.

Cryptography and network security is the concept of protecting the network and data transmission. Security of data is important, as data is transferred over unreliable network. Public-key cryptography provides optimal solutions to many of the existing security issues in communication systems. In our proposed algorithm we have used some of these secure algorithms in order to generate a highly secured algorithm which can deal with the various flaws of these algorithms. rsa, Reil-fence algorithm, substitution and transposition algorithms has been used in the proposed algorithm. Encryption over encryption is done in order to confuse the intruder. The proposed algorithm is used to provide multilevel security.

Due to the resource constraints of Wireless Sensor Nodes the fast multipliers are essential for data processing. In this paper, we propose the rsa processor using Vedic multiplication technique that achieves considerable speed and with reduced area utilization. To multiply two prime numbers we have implemented Nikhilam and Urdva Triyagbagam multipliers. The results of our Hardware implementation on Xilinx Spartan III FPGA can be used for the construction of security architecture in WSN. The delay and area tradeoff leads to the selection of multiplier for rsa processor. The comparative analysis of the two different methodologies is analyzed in terms of speed and area. Urdva Triyagbagam gives good improvement in delay and device utilization compared to Nikhilam Multiplier.

Generalized rsa using 2^k prime numbers with secure key generation

SECURITY AND COMMUNICATION NETWORKS 2016年第17期9卷 4443-4450页

Cryptography is used for secure communication since ancient days for providing confidentiality, integrity and availability of the information. Public key cryptography is a classification of cryptography having pair of keys for encryption and decryption. Public key cryptography provides security and authentication using several algorithms. The Rivest-Shamir - Adleman (rsa) algorithm is prominent since its inception and is widely used. Several modified schemes were introduced to increase security in the rsa algorithm involving additional complexity. In this paper, we introduce a generalized algorithm over rsa that is advanced, adaptable and scalable in using a number of primes. Our algorithm uses 2(k) prime numbers with secure key generation involving additional complexity, making it computationally infeasible to determine decryption key. A user can use 4, 8, 16, 32,. (2(k)) prime numbers for generating public and private components securely. In our algorithm, public key and private key components are generated by making use of N, where N is a function of 2(k) prime numbers. When an attacker obtains a public key component n out of {E, n} by using factorization techniques such as general number field sieve or elliptic curve factorization, he or she can only obtain two initial prime numbers (because n is a product of the first two prime numbers). However, finding the remaining prime numbers is computationally infeasible as no relevant information is available to the attacker. Hence, it is difficult for the attacker to determine the private key component D out of {D, n} knowing the public key component {E, n}. Thus, it is practically impossible to break our system using a brute force attack. Copyright (C) 2016 John Wiley & Sons, Ltd.
