another concept involving key pairs: one for encrypting‚ the other for decrypting. This concept‚ as you will see below‚ is very clever and attractive‚ and provides a great deal of advantages over symmetric-key: • Simplified key distribution • Digital Signature • Long-term encryption However‚ it is important to note that symmetric-key still plays a major role in the implementation of a Public-key Infrastructure or PKI. 1.1 A definition Public-key is commonly used to identify a cryptographic

Digital Signatures Requirements Message authentication protects two parties who exchange messages from any third party. However‚ it does not protect the two parties against each other. In situations where there is not complete trust between sender and receiver‚ something more than authentication is needed. The most attractive solution to this problem is the digital signature. The digital signature is analogous to the handwritten signature. It must have the following properties: •

Abstract This paper gives an introduction to elliptic curve cryptography (ECC) and how it is used in the implementation of digital signature (ECDSA) and key agreement (ECDH) Algorithms. The paper discusses the implementation of ECC on two finite fields‚ prime field and binary field. It also gives an overview of ECC implementation on different coordinate systems called the projective coordinate systems. The paper also discusses the basics of prime and binary field arithmetic. This paper also discusses

Cryptography in Mobile Phones ABSTRACT As mobile networks expand their bandwidth‚ mobile phones‚ as with any other Internet device‚ become substantially exposed to Internet security vulnerabilities. Public key cryptography is a primary concept in implementing wireless device security. Many papers have been written about public key infrastructure‚ this paper does not delve into the deeper mechanisms of PKI(public key infrastructure). Instead‚ it describes the applicative use of PKI in current and

ANALOGUE & DIGITAL SIGNALS Name: - BHAVESH PATWAL Tutor : - JAY PATEL Date: - 20th November‚ 2012 I . Analogue Signals : - Analogue signal is a form of transmitting data such as voice‚ image or video using continuous signals. This is a relatively inexpensive way to transmit data. Analogue communications are usually sent via twisted cables or fibre optic cables and they are transmitted via a carrier signal which is set at a specific frequency. The primary disadvantage of
