Using the output of a stream cipher, how to guarantee the integrity of 4 bytes of data? Well, that is my premise when I asked the question. |

Using the output of a stream cipher, how to guarantee the integrity of 4 bytes of data? I had realized the difficulty of finding the message boundary in case of corrupted stream, but I do terminate the communication in case of corrupted message. And since I am using a stream cipher, I can't easily recover from bytes inserted or removed from the stream. |

Nonce role on stream ciphers But a key/nonce pair can generate a very long pseudorandom stream, I thought I could simply go on generating more and more bytes for the messages as long as the message sequence is not lost... |
