INTRODUCTION
Digital signature is a sort of Cryptography. Cryptography means keeping communications private. It is a practical art of converting messages or data into a different form, such that no one read them without having access to the Ëœkeyâ„¢. The message may be converted using a Ëœcodeâ„¢ (in which case each character or group of characters is substituted by an alternative one), or Ëœcipherâ„¢ (in which case the message as a whole is converted, rather than individual characters). It deals with e ....etc

Abstract
Cryptographic protocol is a precisely defined sequence of communication and computa¬tion steps that use cryptographic mechanisms such as message encryption and decryption. But even when strong encryption algorithms are used, information is not safe and flaws have been found in protocols considered to be secure. So it becomes necessary to verif ....etc

Password Authenticated Key Exchange


ABSTRACT:
Password-Authenticated Key Exchange (PAKE) studies how to establish secure communication between two remote parties solely based on their shared password, without requiring a Public Key Infrastructure (PKI). Despite extensive research in the past decade, this problem remains unsolved. Patent has been one of the biggest brakes in deploying PAKE solutions in practice. Besides, even for the patented schemes like EKE and SPEKE, their security is only heuristic; researchers h ....etc

Definition
Quantum cryptography is an effort to allow two users of a common communication channel to create a body of shared and secret information. This information, which generally takes the form of a random string of bits, can then be used as a conventional secret key for secure communication. It is useful to assume that the communicating parties initially share a small amount of secret information, which is used up and then renewed in the exchange process, but even without this assumption exchanges are possible.

The advantage of quantum ....etc

Introduction:

What is bioinformatics?Can be defined as the body of tools, algorithms needed to handle large and complex biological information.

Bioinformatics is a new scientific discipline created from the interaction of biology and computer.

The NCBI defines bioinformatics as:
Bioinformatics is the field of science in which biology, computer science, and information technology merge into a single discipline”

Voice over IP The protocol specification

Abstract
IP telephony, known in the industry as Voice-over IP (VoIP), is the transmission of tele-phone calls over a data network like one of the many networks that make up the Internet. VoIP involves sending voice transmissions as data packets using the Internet Protocol (IP). In VoIP, user's voice is converted into digital signal, compressed and broken do ....etc

E-CASH PAYMENT SYSTEM


INTRODUCTION
With the onset of the Information Age, our nation is becoming
increasingly dependent upon network communications. Computer-based
technology is significantly impacting our ability to access, store, and
distribute information. Among the most important uses of this
technology is electronic commerce: performing financial transactions
via electronic information exchanged over telecommunications lines. A
key requirement for electronic commerce is the development of s ....etc

Water marking and tamper proofing for software protection
ABSTRACT
We identify three types of attack on the intellectual property contained in software and three corresponding technical defenses.
A defense against reverse engineering is obfuscation, a process that renders software unintelligible but still functional. A defense against software piracy is watermarking, a process that makes it possible to determine the origin ....etc
