A Stream Cipher for Real Time Applications

Using Hadamard transform for cryptanalysis of pseudo-random generators in stream ciphers

“…There are plenty of applications, such as in electronic commerce [1,2] and blockchain [3][4][5], among others. In particular, stream ciphers, which are the object of our present study are useful for protecting data in real-time, like the encryption and decryption of a DVD [6]. Cryptanalysis is the study of methods to reveal the meaning of encrypted information, without access to the secret key.…”
