I'm guessing you need your own copy of Mono.Security only when running on .NET. The solution in such case is easy - use
reflection to load the types you need. If you detect you're running on Mono, do this:

Assembly asm = Assembly.Load ("Mono.Security, Version=2.0.0.0, Culture=neutral, PublicKeyToken=0738eb9f132ed756");

or even

Assembly asm = Assembly.Load ("Mono.Security");

if you don't care for the version. On .NET use:

Assembly asm = Assembly.LoadFrom ("\\path\\to\\local\\copy\\of\\Mono.Security.dll");

And reflect on the returned assembly to get any types you want.

best,
