Secure text message transmission in a 4G compatible MIMO MCCDMA system with combined implementation of Vigenere Cipher and RSA cryptographic algorithm

In this paper, a comprehensive performance evaluative study has been made on a secured MIMO MCCDMA wireless communication system with implementation of Minimum Mean Square Error (MMSE) and ZeroForcing (ZF) Linear channel equalization schemes. The 4G compatible system deploys two channel encoding schemes(1/2-rated Convolutional and CRC ) under BPSK,DPSK QPSK and QAM digital modulations. In the p...

Three-Pass Protocol Implementation in Vigenere Cipher Classic Cryptography Algorithm with Keystream Generator Modification

Vigenere Cipher is one of the classic cryptographic algorithms and included into symmetric key cryptography algorithm, where to encryption and decryption process use the same key. Vigenere Cipher has the disadvantage that if key length is not equal to the length of the plaintext, then the key will be repeated until equal to the plaintext length, it course allows cryptanalysts to make the proces...
