The onus is on you to demonstrate that your scheme is secure [...] It is not that hard to make an insecure scheme whose insecurity cannot be easily demonstrated.
Demonstrating that a scheme is secure would mean proving a negative -- an impossible np-complete problem. That's why it's so difficult to trust *anything*, because even the schemes people think are the most secure today may be broken tomorrow. It may be hard to make a scheme whose insecurity cannot be easily demonstrated, but when it finally is demonstrated, it usually appears to be easy.
