No files with prefix com.apple.security in Library? I have been having issues with Safari not showing https sites.  The best solution I have found googling around seems to be to delete either com.apple.security.plist or com.apple.security.revocation.plist, but in Library/Preferences I have no mention of any com.apple.security file.

I have not found anything that seems applicable to this exact problem.  Could anyone shed light on why this file might be missing, and/or how to restore it?

I have tried the following 


Resetting Safari
Rebooting
Keychain first aid, no errors
Executing "ls -l ~/Library/Preferences/com.apple.*.plist";which showed no file in results.
On my iMac the com.apple.security.plist is located in the Preferences folder in the Local Domain:

    /Library/Preferences


but you were looking in the Preferences folder in the User Domain: 

    ~/Library/Preferences   (aka: /Users/[username]/Library Preferences)


There was no com.apple.security.revocation.plist file in any of the  Preferences folders on my iMac. If one did exist I'd expect it to be in the same Preferences folder as the above plist file.

Check your /Library/Preferences folder for either or both of those plist files.

If you aren't familiar with domains in OS X and how they affect the use of files then you can see Apple's documentation for an overview: About the OS X File System
