Secret Agent Michael Scarn enters his hotel room, only to find it having been ransacked. He needs to send an encrypted message to his handler notifying them that his cover has been compromised.
In order to send encrypted messages, agents need a Cryptographically Secure Pseudo-Random Number Generator. Agent Scarn has two such generators with him, but through some testing, he can tell that one of them has been tampered with.
He doesn't know which of the two PRNGs have been modified; if he uses the wrong one, the rival spy agency will likely be able to decode the message, putting both him and his hander in danger.
Can Agent Scarn still generate secure random numbers for the encrypted message?
