Encryption & decryption of text file and audio using LabVIEW
S. Sruthi, Athira Vijay, Shejo Jose, V M Athira · 2017
Data encryption is employed to provide security to confidential data which thereby denies any unauthorized access. In this project, an efficient design is implemented to encrypt any text file and decrypt it using FFT and IFFT algorithms respectively. The design is implemented in LabVIEW software. The basic operations include encryption in encryptor module, transmission through a communication medium to the decryptor module and the retrieval of original text file at the output of decryptor module. A similar encryption-decryption module is also developed for secure transmission of audio files in a real-time scenario by interfacing myRIO hardware.
