EMBEDDED SECURITY USING PUBLIC KEY 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. Since mobile phones are becoming popular and widely distributed, they are increasingly used for financial transactions and related electronic commerce. Consequently, they will feature applications that also demand adequate security functions. In this regard, the prevailing security system in ....etc
