Fault intrusion-tolerance signature protocol
Jianzhong Zhang · Computer Engineering and Applications Journal · 2013
CA private key is shared based on the new(t, n) secret sharing mechanism. It uses its identification as a share of the private key. Rather than prevent intrusions or detect them after the fact, the project ensures that the compromise of a few system components does not compromise the private key of the CA. These policies of intrusion tolerance, by adjusting the use of cryptographic protocol, and tolerating or preventing part of attacks, protect the safety of cryptographic protocol performance. The approach has realized the security and robustness for the key functions of a database system by using the integration security strategy and multiple security measures.
