In a RC4 cipher, the same traffic key can never be used twice.
True
False
In cryptography, RC4 (Rivest Cipher 4) is a stream cipher. While remarkable for its simplicity and speed in software, multiple vulnerabilities have been discovered in RC4, rendering it insecure. It is especially vulnerable when the beginning of the output keystream is not discarded, or when nonrandom or related keys are used. Particularly problematic uses of RC4 have led to very insecure protocols such as WEP. https://en.wikipedia.org/wiki/RC4 -- USER EDIT: Doesn't this explanation indicate that the answer should instead be FALSE? 2nd Edit: I interpreted the question as being focused on using the same traffic key twice; that's something that should always be avoided for the best security.
