Seems it 'tis the season for warnings about the security of cryptosystems. The New York Times has an article on the latest issue here. It seems that Adi Shamir (the S in RSA) has a note out describing how faults in chip hardware could render cryptosystems insecure. It's not at all clear to me how this differs from analysis where the faults are injected into the hardware (such as described here) because the article doesn't contain any real details.

Shor's algorithm is an algorithm for quantum computers which allows for efficiently factoring of numbers. This in turn allows Shor's algorithm to break the RSA public key cryptosystem.

To understand why serious encryption algorithms are so complex, and why it's
so important to be careful with the critical secrets that make an encryption
system work, it's useful to understand something about how people break
An alert reader sent me a link to a really dreadful piece of drek. In some ways, it's a
rehash of the "Nullity" nonsense from a couple of years ago, but with a new spin.
