InternalsVisibleTo PublicKey is ignored

I have two strong named assemblies A.dll and B.dll. A.dll has internal classes. B.dll uses internal classes from A.dll. I use

[assembly: InternalsVisibleTo("B,PublicKey=[public key of B.dll]")]

in A.dll. It works fine, I can use internal classes from A.dll in B.dll. When I change assembly name in InternalsVisibleTo it stops working, as expected, but if I change only a public key (set wrong public key) it continue working, so it ignored PublicKey parameter.

I use Assembly.Load, for loading assembly.

What is the problem or InternalsVisibleTo not sensitive to PublicKey?

What do you mean by stops working? Does it compile? Does it start? – Emond Aug 04 '14 at 11:45
I have inverse problem, all works, but it shouldn't. Or I don't understand use of PublicKey parameter here. @ctescu – Ilya Khorin Aug 04 '14 at 11:47
Assembly loads dynamically, so it has runtime error. But it works as exepcted, here is no problem. @Erno de Weerd – Ilya Khorin Aug 04 '14 at 11:51

@Ian Ringrose I have another problem – Ilya Khorin Aug 04 '14 at 12:58
Are you sure the assemblies are signed? – Emond Aug 04 '14 at 13:00
Loading should be fine, it should stop you from accessing the internal types – Emond Aug 04 '14 at 13:01
Yes,they are signed and i can get their PublicKey by sn.exe. Problem is that I can access internal types even if PublicKey doesn't match, I thought it should be secured from such attempts. @Erno de Weerd – Ilya Khorin Aug 04 '14 at 13:52
