DES算法的入口參數(shù)有三個(gè)：Key、Data、Mode。其中Key為8個(gè)字節(jié)共64位，是DES算法的工作密鑰；Data也為8個(gè)字節(jié)64位，是要被加密或被解密的數(shù)據(jù)；Mode為DES的工作方式，有兩種：加密或解密，如果Mode為加密，則用Key去把數(shù)據(jù)Data進(jìn)行加密，生成Data的密碼形式作為DES的輸出結(jié)果；如Mode為解密，則用Key去把密碼形式的數(shù)據(jù)Data解密，還原為Data的明碼形式作為DES的輸出結(jié)果。在使用DES時(shí)，雙方預(yù)先約定使用的”密碼”即Key，然后用Key去加密數(shù)據(jù)；接收方得到密文后使用同樣的Key解密得到原數(shù)據(jù)，這樣便實(shí)現(xiàn)了安全性較高的數(shù)據(jù)傳輸。

A paper that I presented on Supervisory Control and Data Acquisition (SCADA) won the second prize at the symposium conducted by the Electrical and Electronics Engineering department of the SRM University. Other topics on which I presented papers were Performance enhancement of wireless sensor networks using directional antennas, Smart card application and wireless communication. Also my research idea titled “Wavelet Based Image Compression Using SPIHT Algorithm “secured third prize in a technical festival.
