Data Encryption Standard (short for des) algorithm is widely used in encryption design. By adopting des algorithm, this paper aims to encrypt and decrypt data files based on FPGA. In this thesis, the author deeply analyzes des algorithm and the workflow, such as IP substitution, S-box substitution, P-box substitution and key substitution. Then by virtue of an analysis on core technology of des algorithm, des algorithm is utilized to realize encryption and decryption of data files, among which, the encryption and decryption processes of des algorithm are basically the same, except for a small part. For example, when generating the key, the encryption algorithm cyclically moves to the left, but the decryption algorithm cyclically moves to the right, etc. Since the encryption and decryption parties must use the same key, des algorithm is also a symmetric algorithm. This paper uses des algorithm to implement data file encryption and decryption based on FPGA.

A system is proposed for generation of security key using R-R interval feature of electrocardiogram (ECG) signals as an input. The system provides a mechanism for verification and identification by generating a security key corresponding to an individual. The system comprises of two independent stages: registration and authentication. Biometric security key, created in the registration stage has been generated using Hamming Distance and the extended version of the triple des algorithm. Biometric security key generation, verification, authentication and performance of the biometric security key have been assessed using R-R interval of ECG signals taken from the standard MIT-BIH database. The performance of the proposed biometric security key has been tested for the parameters like FAR, FRR, GAR, HTER and accuracy. The simulation results for 64-bit, 128-bit and 256-bit biometric security key indicate that the performance of the proposed biometric security key is reasonably good for a security system.

Under the condition of unified communications within heterogeneous network environments, due to the presence of unified security measures such as network protocol, encryption firewalls and so on, communication within the network environments in good availability and security. As a result of the large number of business networks and significant network level in current communication network for electric system, heterogeneous network is applied in all aspects of its communication. However, in order to guarantee the availability, the safety of heterogeneous network is reduced. After studying the issues and current situation about crossing heterogeneous network, this paper makes a further research on symmetric key cryptography and asymmetric key cryptosystem, and then proposes a composite encryption algorithm based on the RSA algorithm and improved des algorithm. Finally, the algorithm is proved to have a good security by case analysis.

Disease diagnosis is one of the diligences where data mining instruments are providing successful outcomes. All the disease (like Heart Disease, Cancer and HIV) is the chairing cause of death all over the world. Some of the diagnostic and laboratory procedures are in cursive, costly and painful to patients. Now a day's diabetes is an inveterate disease that needs to be consistently monitored to preserve the blood sugar levels within normal ranges. To maintain blood sugar level in rule stage, taking medicine based on sugar level provides effective result for all diabetic patients. For that here we propose an Android application to reduce the time and travelling expenses, which is easy to use by any user and for the quick response as to what has to be done when you get to recognize your blood sugar level, using a Smartphone application. This system designed to be a long term health companion for patient with diabetic. A smartphone based patient platform allowing manual input of glucose and variables regarding blood glucose levels (e.g. Meal carbohydrate substance, exercise) and providing real time insulin Recommendations. Here a user input data is encrypted by des algorithm for maintaining the data. It allows patients to get Insulin based on sugar level at any time with the help of cloud server with a proficiency of apriori algorithm. Here cloud server used for suggesting Insulin based on user old medical history. By using this system user can get suggestion with efficient way and suitable medicine.

This article proposes a novel approach to cryptosystem design to prevent power analysis attacks. Such attacks infer program behavior by continuously monitoring the power supply current going into the processor core. They form an important class of security attacks. Our approach is based on dynamic voltage and frequency scaling (DVFS), which hides processor state to make it harder for an attacker to gain access to a secure system. Three designs are studied to test the efficacy of the DVFS method against power analysis attacks. The advanced realization of our cryptosystem is presented which achieves enough high power and time trace entropies to block various kinds of power analysis attacks in the des algorithm. We observed 27% energy reduction and 16% time overhead in these algorithms. Finally, DVFS hardness analysis is presented.

High-speed wireless network technologies play a vital role in autonomous vehicle communication systems (AVS), i.e., IoV (Internet of Vehicles), and enhance the effectiveness and reliability of the communication network. Since the size of IoV communication is rapidly growing, it is now an essential part of our regular routines. Due to its dynamic nature and massive size, it is essential to avoid any miss-communication and protect the data privacy of each *** to link remotely to each other and to various platforms and groups that may be using the same com-munications system. This quality link between vehicles and the need for information exchanges among vehicles introduces vulnerability and threats that can be exploited by cybercriminals. This research emphasizes on enhancing data security in real-time IoV communication. It presents a trust-driven privacy method using encryption and steganography for IoV. This method uses an Efficient algorithm for Secure Transmission (EAST) that integrates encryption and steganography algorithms. The proposed EAST is then compared to the various current state of arts, i.e., AES (Advanced Encryption Standard), des (Data Encryption Standard), G-des (Generalized des), and Standard LSB on the basis of various performance measuring parameters, i.e., encryption and decryption time, efficiency, avalanche effect, PSNR, and file cover size. Experimental results are promising for the proposed EAST method, which reported a better time efficiency of 0.86 ms, avalanche effect of 58.81%, and PSNR of 78.58%, compared to the current state arts.

In order to overcome the problems of poor data security, low integrity and long storage time of traditional methods, this paper proposes a dynamic and secure storage method of enterprise financial data based on cloud platform. Firstly, the absolute correlation degree of the data in the financial database is calculated by using the grey correlation analysis method, and the data mining and clustering are carried out according to the results of the absolute correlation degree calculation. Then, the des algorithm is used to encrypt the clustering results of financial data and remove redundant data. Finally, according to the cloud platform access time length, access frequency, and the relationship between enterprise financial datasets, the data dynamic security storage is achieved. Experimental results show that this method can encrypt all data, the average integrity of the storage results is 9.7, the average storage time is 0.51 s, and the practical application effect is good.

Smart Card has complications with validation and transmission process. Therefore, by using peeping attack, the secret code was stolen and secret filming while entering Personal Identification Number at the ATM machine. We intend to develop an authentication system to banks that protects the asset of user's. The data of a user is to be ensured that secure and isolated from the data leakage and other attacks Therefore, we propose a system, where ATM machine will have a QR code in which the information's are encrypted corresponding to the ATM machine and a mobile application in the customer's mobile which will decrypt the encoded QR information and sends the information to the server and user's details are displayed in the ATM machine and transaction can be done. Now, the user securely enters information to transfer money without risk of peeping attack in Automated Teller Machine by just scanning the QR code at the ATM by mobile application. Here, both the encryption and decryption technique are carried out by using Triple des algorithm (Data Encryption Standard).
