How should I protect my Unipass and its private key?
The best way to protect your Unipass and its private key is to protect your computer from unauthorised access by keeping it physically secure. Use access control products or operating system protection features (such as a system password). You should take measures to protect your computer from viruses, because a virus may be able to attack a private key. We recommend that you also protect your private key with a good password. See http://csrc.nist.gov/publications/nistbul/csl96-08.txt concerning private key security and http://csrc.nist.gov/publications/nistbul/csl90-08.txt concerning computer virus attacks.
