In the digital world, the demand for data security during communication has increased. Hash functions are one of the cryptographic algorithms that provide data security in terms of data authenticity and integrity. Nowadays, most online applications require user authentication. These authentications are done on the server-side, which he must manage. As the number of applications increases, building a one-way function will be faster for calculating a hash value for small data such as passwords. In this paper, we will present a sequential cryptographic algorithm and its parallel implementation. We performed security analyses, executed comparisons for different amounts of data, and provided steps for further developing this algorithm. With the construction of this one-way function, we have provided the calculation of hash value in a shorter time for data in small quantities, which speeds up the authentication process on the server and thus speeds up the online services provided by the respective applications. A comparison was made between sequential implementation, parallel implementation on the CPU, and parallel implementation on the GPU using CUDA (Computer Unified Device Architecture) platform.

Data security is one of many problems that we face in IoT implementation. One of the problems with data security is we cannot assure that the data we received in the server-side is truly our data that we send from client-side or sensor-side. With that problems, comes some solutions like encryption and decryption method or some basic authentication planted on the server-side. In this research, we propose some encryption and decryption method that can be easily implemented on both server and sensor-side and then we analyze the complexity of its algorithm. This research aims to create some authentication process for the data that server-side receive from the sensor-side by creating encrypted ID consisting of 6 digits of alphanumeric and useful for identification process in system, so the server can recognize the data and validate it.

In data mining, Apriori technique is generally used for frequent itemsets mining and association rule learning over transactional databases. The frequent itemsets generated by the Apriori technique provides association rules which are used for finding trends in the database. As the size of the database increases, sequential implementation of Apriori technique will take a lot of time and at one point of time the system may crash. To overcome this problem, several algorithms for parallel implementation of Apriori technique have been proposed. This paper gives a comparative study on various parallel implementation of Apriori technique .It also focuses on the advantages of using the Map Reduce technology, the latest technology used in parallelization of large dataset mining.

Cryptographic Techniques

Cryptography is an old idea and science, but its approach exists and plays a large role in modernization today. Conventional cryptographic techniques form the basis of today's cryptographic algorithm. The different categories of algorithms have their respective features; internally, in performance and implementation. Cryptographic schemes and mechanisms have undergone continuous improvement. The application of cryptography has grown increasingly, ranging from limited use in state institutions to widespread use by private individuals and companies. The increased use of the Internet has significantly influenced the nature of applications and the way we communicate. Data security dictates the use of different cryptographic techniques. For this reason, we analyze in detail the various coding techniques by evaluating their performance and efficiency. Regarding the new paradigms in cryptography there are also new cryptographic schemes whose application requires detailed study and analysis. The classical cryptography algorithm is the oldest algorithm that was used long before the cryptographic system was discovered. Currently, the system has been widely applied to secure data, and using new methods in a way to improve existing methods. In this thesis the use of cryptographic methods using the C # programming language will be discussed.

As we all known that cryptography is a procedure to hide data so that it can’t be access or modified by any unauthorized entity. At the present digital world security is a main concern. To maintain this security there are many cryptographic algorithm exist. But the world technology grew each and every day so we have to find some new algorithms to maintain the security at higher level. In the proposed and implemented work used artificial neural network to increase the security during data communication in digital world. Autoencoder Neural Network is a new approach in the era of digital world so that used here in cryptographic algorithm to increase the strength of the security. There are three basic aims of cryptography availability, privacy and integrity easily achieved by this new approach. This work examine that the attacker can’t get access the data however he/she exist in the same network or not. Neural Network’s uncertainty property make this possible. This approach also examined on different data size and key size. Proposed work used the autoencoder for encryption and decryption. The final experimental result show our purposed algorithm efficient and accurate and also show how this approach perform better. Proposed and implemented algorithm can be easily used for secure data communication with more efficiently

Area Of Concern

In today's society, data security is the big problem for every business organization or an individual. Most found threat is theft of personal data and information. With time digital data become more prevalent, personnel try to secure their information by using highly encrypted passwords and authentication identities, but, the misuse and theft of these security measures are rising in lot of theft cases Taking advantage of security flaws in authentication identities ends up in cards being duplicated or counterfeited and hence misused. This increasing fight with cyber security has been the sole reason of  making  biometric security systems, the  important area of concern is that how do  one can implement the biometric security for increasing of data security.  First unique feature which is found different in every human is Fingerprints; Humans have used fingerprints for personal identification. Presently, most of the organisation use  fingerprint recognition for authentication process  it is one of the oldest and most commonly used biometrics, with high accuracy & generally easy and efficient and fast.  In this paper we propose the idea to use fingerprint recognition along with the user authentication password or to access the data or information. Since the only person who can access information is the person linked to it, no thief can gain access. It also makes your data, very hard for cyber criminals to hack into.

One Time Password

The password system is the most conventional method among validation techniques on the internet and is operated more easily and effectively than other methods. However, it is a vulnerable method against attacks such as eavesdropping or replay attack. To prevail over this problem, OTP (One Time Password) technique is used. The most popular OTP is HOTP algorithm, which is based on one-way hash function SHA-1. The recent researches show the weakness of the hash function. So, in this paper we created a module which uses another cryptographic algorithm. Cryptography in the current world serves an important role in data security. Cryptography means writing of secret codes (cipher text) which is in an unintelligible form and cannot be read unless we have a perfect key to decode it. The proposed method is AES algorithm (128 bit) followed by Middle Square method to generate an OTP. As OTP is a 4-6 bit number we will decrease the AES output to a 4-6 bit through Middle Square method and this OTP can be used as a security tool in many cases like online transaction purposes.

Digital Identities

In the digital world, many organizations are developing different applications (with different purposes) where users are generally represented by a heterogeneous set of attributes. From time to time, depending on the context, different attributes can provide different digital identities for the same user, often involved in the identification/authentication processes. In the personalized service provision perspective, the scope of identity management becomes much larger, and takes into account information susceptible to change such as user profile information as a whole. Many purely user-centric identity management systems has emerged in the few last years, among them the Higgins project that provides the user with a direct control over his/her data and covers some data security issues. However, a complete user-centric view of extended user identity management is not realistic, in our opinion. In this paper, the authors present G-Profile: a hybrid, open, general-purpose and flexible user modeling system for extended identity management in multi-application environments. G-Profile also tackles the trade-off between users’ and applications’ requirements.
