IDS, IPS and encrypted traffic

Hello everybody,

I’ve been looking around the net for a while, trying to find some theoretical and practical approaches to solve the 
problem of analyzing encrypted traffic.

I know, that there is a need to decrypt the traffic before analyzing it, but I haven’t found any concrete solutions 
neither for NIDS nor for HIDS yet. Some HIDS vendors announced that their products are capable of analyzing encrypted 
traffic, but I didn’t succeed to find any details about that.

Does anybody know some products or papers which deal with the problem of 
analyzing encrypted traffic?

Thanks in advance,
 Daniel Hamburg
