His 1987 doctoral dissertation was on the subject of computer viruses. Fred Cohen experimented with computer viruses and confirmed Neumann's postulate and investigated other properties of malware such as detectability and self-obfuscation using rudimentary encryption. This constituted a plausibility result in computability theory. John von Neumann showed that in theory a program could reproduce itself. The notion of a self-reproducing computer program can be traced back to initial theories about the operation of complex automata. ![]() History įor a chronological guide, see Timeline of computer viruses and worms.

The irony is that the only thing he teaches is sexual assault if it was played out in real life.
