Iran GPS Spoofing and the RSA Cipher

[Ian Mason]

I do wish people would check their facts sometimes. The linked article  
asserts that "GPS (M-code) is protected against spoofing by the RSA  
cipher" - it is not, it's protected by a keyed PRNG. You don't have to  
be an ace cryptologist to figure this out, you just need to look up  
"GPS signal" on Wikipedia.
