Security system for encrypted environments (S2E2)

First we revisit three (BGLS, MBGLS and GZZ) verifiably encrypted signature schemes \cite{BGLS03,H04,GZZ05}. We find that they are all not strong unforgeable. We remark that the notion of existential unforgeable is not sufficient for fair exchange ...

Because of a lack of attack signatures and different forms of attacks, signature-based network intrusion detection systems currently provide insufficient protection for industrial control traffic. A combination of two anomaly detection approaches found ...

Stepping-stone attacks are often used by network intruders to hide their identities. In a stepping-stone attack, attacking commands are sent indirectly to the victim through a chain of compromised hosts acting as "stepping stones." In defending against ...
