high-level of security. Cryptography only scrambles a message into a form which can’t be understood whereas steganography hides the information in a vessel like Image‚ Audio or Video. In this Paper‚ a combination of four techniques is done to analyze the level of security provided be them when they are combined. For cryptography‚ Diffie-Hellman and One Time Pad cryptography are used. For Steganography‚ DCT and DWT based techniques are considered. It is further concluded that cryptography combined with steganography

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

Public Key Infrastructure (PKI). PKI is a broad subject matter and is constantly evolving to meet the growing demands of the business world. This paper will address PKI at a relatively high-level and will not include details regarding the underlying cryptography (Weise‚ 2001). This paper will cover the history behind PKI‚ why we should us PKI‚ its purposes and functions how PKI works. Introduction With today’s security threat

there has been little evidence to demonstrate the success of these schemes in stopping fraudsters‚ scammers‚ and identity thieves. This may be attributed to combinations of poor usability‚ lack of trusted interfaces‚ the absence of smart-card cryptography that takes full advantage of the available computation resources‚ and inadequate authentication protocols. In this paper‚ we explain the shortcomings and vulnerabilities of each of these systems‚ and then explain requirements of a secure and usable
