Re: Slightly more complicated as far as AES is concerned

that's the first time I hear this...

that's a related-key vulnerability (it's easier to perform for AES-256 than it is for AES-128), if your keys come from a PRF (as they do in S/MIME, TLS and IPsec, among others), it's only of academic importance

BGP has no security, the problem is that it was designed at the time when it was not a problem, the world changed around it - but it's a problem as well known as the lack of security in HTTP
