31. A Study of Encryption Algorithms AES, DES and RSA for Security 
4
5In recent years network security has become an important issue. Encryption has come up as a solution, and plays an important role in information security system. Many techniques are needed to protect the shared data. The present work focus on cryptography to secure the data while transmitting in the network. Firstly the data which is to be transmitted from sender to receiver in the network must be encrypted using the encryption algorithm in cryptography. Secondly, by using decryption technique the receiver can view the original data. In this paper we implemented three encrypt techniques like AES, DES and RSA algorithms and compared their performance of encrypt techniques based on the analysis of its stimulated time at the time of encryption and decryption. Experiments results are given to analyses the effectiveness of each algorithm.

132. Data Encryption and Decryption Using RSA Algorithm in a Network Environment  
14
15One of the principal challenges of resource sharing on data communication network is its security. This is premised on the fact that once there is connectivity between computers sharing some resources, the issue of data security becomes critical. This paper presents a design of data encryption and decryption in a network environment using RSA algorithm with a specific message block size. The algorithm allows a message sender to generate a public keys to encrypt the message and the receiver is sent a generated private key using a secured database. An incorrect private key will still decrypt the encrypted message but to a form different from the original message.

233. Data Encryption and Decryption process Using Bit Shifting and Stuffing (BSS) Methodology  
24
25Commonly in encryption or decryption process some of the characters are inter changed by using some encryption and decryption algorithms (like DES, IDEA) with key. But in Bit Shifting and Stuffing (BSS) system to represent a printable character it needs only seven bits as per its ASCII value. In computer system to represent a printable character it requires one byte, i.e. 8 bits. So a printable character occupies 7 bits and the last bit value is 0 which is not useful for the character. In BSS method we are stuffing a new bit in the place of unused bit which is shifting from another printable character. So in this BSS methodology after encryption, for every eight bytes of plain text it will generate seven bytes cipher text and in decryption, for every seven bytes of cipher text it will reproduce eight bytes of plain text. 
26
27It is related in our topic because it covers the security system using the encryption algorithm on characters ASCII value also checks bit shifting and stuffing or BSS.

334. An Analysis of Encryption and Decryption Application by using One Time Pad Algorithm 
34
35Security of data in a computer is needed to protect critical data and information from other parties. One way to protect data is to apply the science of cryptography to perform data encryption. There is wide variety of algorithms used for encryption of data, this study used a one-time pad algorithm for encrypting data. Algorithm One Time Pad uses the same key in the encryption process and a decryption of the data. An encrypted data will be transformed into cipher text so that the only person who has the key can open that data. Therefore, analysis will be done for an application that implements a onetime pad algorithm for encrypting data. The application that implements the one time pad algorithm can help users to store data securely.

84
85Encryption is the process of transforming plaintext into the ciphertext where plaintext is the input to the encryption process and ciphertext is the output of the encryption process. Decryption is the process of transforming ciphertext into the plaintext where ciphertext is the input to the decryption process and plaintext is the output of the decryption process. There are various encryption algorithms exist classified as symmetric and asymmetric encryption algorithms. Here, I present an algorithm for data encryption and decryption which is based on ASCII values of characters in the plaintext. This algorithm is used to encrypt data by using ASCII values of the data to be encrypted. The secret used will be modifying o another string and that string is used as a key to encrypt or decrypt the data. So, it can be said that it is a kind of symmetric encryption algorithm because it uses same key for encryption and decryption but by slightly modifying it. This algorithm operates when the length of input and the length of key are same. 
86
87It helps us to get information about the encryption algorithm also symmetric data and ASCII values to be encrypted.

97The advent of information technology (internet) some decades ago has brought about many changes in the way information is being disseminated and exchanged between people, between nations and as well in the whole world. Long ago, the issue of information "theft" has evolved worldwide and concerns about how to remediate it are getting the attention of experts in the area of Information Security. Today, with the current proliferation of some newly invented methods in cryptanalysis it is obvious that information security is the panacea. In this paper, our strategy used is to apply the encryption methods of the AES and MD5 following some steps in the encryption process in order to produce an outcome of file that will as a result be hashed and strongly decrypted through the robust software for file storing. The most important aspect of our application is the intervention of those elements in the process of the encryption to produce an interwoven hashed result which can escape the tricks of malicious operations by eavesdroppers. Results of the encryption have shown that the software can provide a large scale of file encryption since binary, text and any other file type can be encrypted successfully.

109Cryptographic technique is one of the principal means to protect information security. Not only has it to ensure the information confidential, but also provides digital signature, authentication, secret sub-storage, system security and other functions. Therefore, the encryption and decryption solution can ensure the confidentiality of the information, as well as the integrity of information and certainty, to prevent information from tampering, forgery and counterfeiting. Encryption and decryption algorithm's security depends on the algorithm while the internal structure of the rigor of mathematics, it also depends on the key confidentiality. Key in the encryption algorithm has a pivotal position, once the key was leaked, it means that anyone can be in the encryption system to encrypt and decrypt information; it means the encryption algorithm is useless. Therefore, what kind of data you choose to be a key, how to distribute the private key, and how to save both data transmission keys are very important issues in the encryption and decryption algorithm. This paper proposed an implementation of a complete and practical RSA encrypt/decrypt solution based on the study of RSA public key algorithm. In addition, the encrypt procedure and code implementation is provided in details.

12713. An ASCII value based text data encryption System  
128
129Encryption is a process of generating secret text from the input text using a secret key and a encryption algorithm. Input text is referred to as plain text and the secret text generated is known as cipher text. Encryption algorithms are mainly divided into two categories which are symmetric key encryption algorithm and asymmetric key encryption algorithm. In Symmetric key encryption algorithm the same key is used by both sender and receiver but in asymmetric key algorithm sender and receiver both uses the different keys. In this paper, we present a technique based on symmetric key encryption algorithm which uses ASCII vales of input text to encrypt the data. Text data encryption techniques are very useful in data communication where one user want to send some secret messages to other users. 
130
131This will help us to use symmetric key algorithm and generated text.

141Data Security is a challenging issue of data communications today that touches many areas including secure communication channel, strong data encryption technique and trusted third party to maintain the database. The rapid development in information technology, the secure transmission of confidential data herewith gets a great deal of attention. The conventional methods of encryption can only maintain the data security. The information could be accessed by the unauthorized user for malicious purpose. Therefore, it is necessary to apply effective encryption/ decryption methods to enhance data security. The multiple encryption techniques of present time cannot provide sufficient security. In this research paper, the new encryption technique named as ―Multiphase Encryption is proposed. In this encryption technique, original data is encrypted many times with different strong encryption algorithms at each phase. This encryption technique enhances the complexity in encryption algorithm at large extent

171 Cryptography is only thanks to succeed information security. This is often done by changing the info into cipher text. The existing manner of doing this was victimization Armstrong range. Since there square measure few Armstrong numbers so a crypt-analyst will easily realize the key. During this paper, we tend to square measure proposing a brand new algorithm for cryptography technique, UPMM rule, which is applied on computer code worth of knowledge. Computer code values square measure encrypted using a key involving word numbers and distinctive alphanumeric id that is additionally reborn into computer code worth to provide authentication over the network. This paper offers a technique to send information over the network in set of 3 keys. Normally a crypt-analyst will simply determine the key but in this approach a combination of word range and matrix multiplication is employed for encrypting the info. within the same manner decryption will be done at receiver's facet by victimization inverse of encoding matrix.

181An Image Encryption and Decryption Using AES (Advance Encryption Standard) Algorithm is proposed in this paper. Due to increasing use of image in various fields, it is very important to protect the confidential image data from unauthorized access. The design uses the iterative approach with block size of 128 bit and key size of 256 bit. The numbers of round for key size of 256 bits is 14.

19920. A New Approach towards Encryption Schemes: Byte – Rotation Encryption Algorithm  
200
201Information security is a challenging issue in today’s technological world. There is a demand for a stronger encryption which is very hard to crack. Earlier many researchers have proposed various encryption algorithms such as AES, DES, Triple DES, RSA, Blowfish etc. Some of them are most popular in achieving data security at a great extent like AES and Blowfish. But, as security level is increased, the time and complexity of algorithm is also increased. This is the major cause of decreasing the speed and efficiency of the encryption system. In this paper we have proposed a new encryption algorithm “Byte – Rotation Encryption Algorithm (BREA)” with “Parallel Encryption Model” which enhances the security as well as speed of the encryption scheme. The BREA is applied on different blocks of plaintext and executes in parallel manner through multithreading concept of single processor system. This paper is an attempt to invent a new encryption model which is secure and very fast.

203This will cover the current approach in encryption also new knowledge to use.
