Security Measures And Encryption Standard

Public key and private is a type of encryption technique that can be used ensuring that the communication on the network is secured. When you sending a message to someone through the network, will need to use the public key of the receiver and the receiver will use the private key to decrypt the message. This encryption will avoid unauthorised access to the message such as reading

With the ever increasing surge of digital communications and transactions, a tougher level of security is essential in order to safeguard the user and their data transactions. Systems, personal computers, mobile phones, servers, and even smart cards are all being used everywhere and there is a need to secure communications. With the influx of data management, there is a clear race between the two challengers in the game known as Information Security between developers and the hackers. PKI was designed to influence the Internet infrastructure for means of communication (Samuelle, 2011). While decreasing antagonistic misuse of data, reducing data theft, and providing an extra layer of trust through key pairs and

In today’s world of instant connectivity and information at users’ fingertips, it’s vital that sensitive information is safeguarded against those who seek to do personal harm and profit from gaining access to the data. The key behind keeping information safe is the method in which it’s protected and encrypted. In order to appreciate how information is secured, users must understand the encryption concepts behind it. To do this, one must comprehend the current encryption standards, the trends and developments in encryption technology, the importance of securing data, the government’s regulations pertaining to encryption, the companies involved in research and implementation, the implications of leaked or stolen data, and a brief look into

The three different Advanced Encryption Standard(AES) implementations are computed on a parallel,pipelined and sequential architecture. This architecture is the field programmable gate array (FPGA). The FPGA is capable of performing parallel operations. It consists of logic blocks which are seperated by reconfigurable interconnects. The main advantage of implementing AES on hardware is the adaptability. According to the programming every time the FPGA fuses i.e. reconfigure itself. Due to this adaptability it has became popular for different complex implementations. Whereas in processor the hardware is fixed. Once the processor is designed, it ‘s hardware remains dedicated and connot be reconfigured. Also, the processors are sequential.So, if such algorithms that require large computations are processed on processors, the processing time would be very slow and the throughput will decrease to a large extent. In this proposed system, three diffrent implementations of AES have been proposed so that the throughput is increased three times. This process is carried out in a pipeline, parallel and sequential manner.

Often there has been a need to protect information from 'prying eyes'. In the electronic age, information that could otherwise benefit or educate a group or individual can also be used against such groups or individuals. Industrial espionage among highly competitive businesses often requires that extensive security measures be put into place. And, those who wish to exercise their personal freedom, outside of the oppressive nature of governments, may also wish to encrypt certain information to avoid suffering the penalties of going against the wishes of those who attempt to control.

CRYPTOGRAPHY is the most important part to secure any business by securing the communication range. In this project important topics of cryptography that should be known in general is discussed . How decoding and encoding in done with the help of cryptography to secure any communication. How it helps to maintain authenticity of any industry or company. Cryptography helps in making transactions by keeping data secure. It also protect passwords, ATM pins etc. from hackers. Cryptography maintains aspects which is authenticated like Confidentiality, authenticity & integrity. In this project it is described how cryptography converts the essential data in coded form and how it is changed using terms encryption and decryption. In this undertaking distinctive keys utilized for encryption and unscrambling is examined like cryptography mystery key and open key. In this a short portrayal of encryption is given which is the starting venture in cryptography. Encryption takes an arrangement of calculations, or scientific articulations, to scramble information from its unique organization into one undecipherable. Purpose of cryptography is discussed in the project. How secret codes were used in ancient period is briefly described. Now key is used in cryptography how key convert the data from one format to another is discussed. There are three keys in cryptography public, private and shared keys. A brief discussion about how these

In today’s world a lot of data is being exchanged via the internet. Sensitive data such as official documents, bank details, credit card information, as well as personal information is being sent online. To maintain the confidentiality, integrity and availability of this data, it needs to be encrypted. Cryptology deals with cryptography and cryptanalysis, i.e., encryption and decryption of information. To keep the data safe from intruders, various cryptographic algorithms are implemented. Parallel processing enhances the speed of these systems and makes it more efficient. Parallel computation can be performed using multicore processors by parallelizing the execution of algorithms in multiple cores. The main area of focus will be the parallelization of Advanced Encryption Standard (AES) algorithm, which is widely in use today. The paper reviews the implementation of AES algorithm on multiple cores and the speedups observed in the process.

We will provide a brief Description to Elliptic Curve Cryptography and the implementation of new attacks on the cryptography in this section. If you want to a comprehensive description about to ECC than you can find it in [10],[11]. A reader want to go through a summary of power analysis attacks, by far the class of implementation attacks, we refer you to [8].

Personal data stored in the Cloud may contain account numbers, passwords, notes, and other important information that could be used and misused by a miscreant, a competitor, or a court of law. These data are cached, copied, and archived by Cloud Service Providers, often without user’s authorization and control. The system proposed consist of the key generation logic for cloud server which helps random key generation security for ABS. In addition, our system secures the data and generates the key for each transaction by

Cryptography is defined as the art or process of writing in or deciphering secret code: any system of secret writing. Encryption is used in electronic systems to achieve privacy and authentication of information. The privacy requires, two questions need to be answered: what are the consequences of unauthorized access to or disclosure of the valuable information, and how often the possibility of unauthorized access to or disclosure of information. Authentication addresses the issues of whether data is from the correct source or if it has been unauthorized with. Functions embedded with in cryptographic systems help ensure data integrity by guaranteeing authenticity of a message and allowing the use of digital signature, a data block attached to a message that binds the message to a sender so that it can be verified by the receiver or others.

Abstract— Crucial methods are employed to deploy the majority networks to acquire the data. Modern improvements stores, transfer data at higher rate. Traditional methods which provide security to the information. Using single encryption algorithms are more prone to issues and these are implemented without knowing its shortcomings.
