Yoga Distra}, title ={KOMBINASI ALGORITMA RSA DAN RUNNING KEY VIGENERE CIPHER PADA PENGAMANAN DATA APLIKASI REGISTRASI ULANG (STUDI KASUS: STT-PLN JAKARTA)}, year={2016}, url={http://156.67.221.169/4731/}, abstract={The usage of re-registration applications for prospective students at STT-PLN has been made since 2015 at registrasi.pmb.sttpln.ac.id page. There are any important data that need security during the re-registration application for the degree of confidentiality and crucial, such as profile data and financial data. Systems on re-registration application in STT-PLN has not applied the techniques of security of the data that uploaded or downloaded by the user so that the data on re-registration application vulnerable from data tapping and other cyber crimes. The Writer through this research improves the quality of data security on the re-registration application at STT-PLN by implements cryptographic technique uses a combination of RSA (Rivest-Shamir-Adleman) and Running Vigenere Cipher Key algorithms to reduce the possibility to discover the secret key to access the data. Results from this research is the data that contained in the re-registration applications for prospective students at STT-PLN can be gated so that no misuse of data by parties who are not responsible.} }
