碩士 === 國立臺灣科技大學 === 電子工程系 === 94 === Human life gets more and more dependent on internet as it grows rapidly. By means of internet, we can not only transfer text, audio, and video data, but also buy goods and pay for them. But in a public domain like internet, private personal information can be captured easily and therefore encryption is necessary to prevent captured data readable. Based on a developing platform with Samsung S3C2410 as its CPU, this thesis develops a internet transfer application that encrypts files with RSA before sending out via internet, and decrypts them after receiving at receiver end. RSA is currently the most popular public key cryptographic system. It's quite appropriate to use when transferring private information under public domain and it can also be used for digital signature and identification certification. S3C2410, a touch-panel-supported CPU produced by Samsung, is considered suitable for mobile devices such as PDA. Linux, the operating system we use on the developing platform, is capable of great portability, efficient network transfer, support for a great deal of peripherals, and short time to market, and most important of all is that it's open source.
