Elliptic curve diffie-hellman 571 on googleTM android

Abstract

The elliptic curve cryptography (ECC) offers competitive level of security, as

compared to RSA/DSA, using smaller key sizes. For instance a 1024 bit strength for

RSA encryption can be performed using ECC via a 80 bit parameter strength of field

size 163 bit. As can be seen the size of the key strength is reduced by multiples. With

the understanding on the advantage of ECC, the goal of this project is to develop a

Secure Short Message Service (SMS) application coupled with cryptographic

abilities via Google Android mobile platform. The use of Android mobile handsets

has increased in the recent years and its OS implementation has extended to tablet pc.

This report would summarize the works of this project including design and

implementation of ECC for key exchange coupled with AES encryption. This report

also covers the performance analysis of the application.
