The end-to-end-verifiability enables software-independent verification of remote electronic voting systems. Each voter should be able to convince himself that his vote was “cast as intended”, “recorded as cast” and “tallied as recorded”, Each voter should be able to convince himself that his vote was “cast as intended”, “recorded as cast” and “tallied as recorded”, regardless of the software used.

In this thesis different approaches of verifiability are demonstrated. In addition, it is examined whether new safety problems and points of attack have emerged. ElGamal as an asymmetric key cryptography system and Data Encryption Standard DES as a symmetric key cryptography system, both of algorithms will be compared using the time complexity analysis and computer simulation. The result of time The result of time analysis shows elamal different complexity for both algorithms, there is quadratic complexity for ElGamal Algorithm and Linear Complexity for DES algorithm.

Input that is used by ElGamal algorithm is the private key, while for DES algorithm is the plaintext’s size. Based on result of simulation using a computer program, it shows a significant timing differences, ElGamal’s time execution is longer than DES. This is caused by differences of arithmetic operations that is used by each algorithms. Preserving confidentiality, integrity and authenticity of images is becoming very important.

In the present paper the authors introduced an algorithm for encrypting useful data at bit level. The authors have used a new technique of introducing noise wave over the bit patterns of the plain text to encrypt it. Noise has been defined as the complement of the present bit pattern. Certain window layers have been selected over the bit patterns and noise wave has been made to propagate over those pattern in concentric circular fashion thus encrypting the whole bit text present.

Windows are picked up from the bit patterns randomly and noise wave is made to propagate from any random position with a random intensity. Noise propagates algiritma the medium with decreased intensity as one move farther from the source of noise using natural laws. The method has been applied on some standard text and the output has been found to be totally unpredictable.

Two servers Password Authentication with Results. There are many ways to use two servers for authentication purpose like symmetric and asymmetric authentication servers.

In symmetric authentication server two servers contribute equally to each other for the authentication purpose.

In asymmetric two servers one server helps to another server for the authentication purpose. In this paper two symmetric servers for the purpose of authentication.

This is first system that providing periodic backup facility. Also it is showed here that how the two server contribute equally in process of password authentication scheme.

Algorotma security of Elgamal algorithm lies in the difficulty in calculating the discrete logarithm on large number of prime modulo that attempts to solve this logarithm problem becomes very difficult.

In this process requires a secure prime number is used as the basis for forming public key while any random number used as forming of the private key. In the previous research is used secure prime number on key generating process but does not explain the reasons of using the secure primes. This research tried to compare using secure and elgammal primes in elgamal key generating algorithm.

From the analysis it can be concluded that using secure and unsecure of prime numbers, the process of key generating, encryption and decryption can run well, the greater value of prime numbers are used, the greater the capacity of the ciphertext. To overcome the problems faced in symmetric key algorithms, people have chosen Asymmetric Key algorithms for communication.

Communication with Asymmetric algorithms will give us transmission of information without exchanging the key Communication with Asymmetric algorithms will give us transmission of information without exchanging the key. Public-key cryptography refers to a cryptographic system requiring two separate keys, one of which is secret and one of which is public.

Public-key cryptography is widely used.

It is an approach used by many cryptographic algorithms and cryptosystems. RSA and Diffie—Hellman key exchange are the most widely used public key distribution systems, while the Digital Signature Alhoritma is the most widely used digital signature system. In this report we are mainly concentrating on some asymmetric algorithms which are mostly used. It also gives brief mathematical explanations. The RSA algorithm is the algortma commonly used encryption and authentication algorithm and is included as part of the Web browsers from Microsoft and Netscape.

RSA is an algorithm for public-key cryptography that is based on the presumed difficulty of factoring large integers, the factoring problem. The RSA algorithm involves three steps: ElGamal System is a public-key cryptosystem based on the discrete logarithm problem.

It consists of both encryption and Signature algorithms. ElGamal encryption consists of three components: In this we concentrate on the algorithms Cyclic Groups, Modular Exponentiation solving algorithms etc. Ads help cover our server costs.
