> The encrypted file – if The Register understands the paper correctly – embeds actions that are permitted on that file (for example, the ability to read and write to parts or all of the file. The Evaluate function is able to use the combination of the public key and permitted actions (described as circuits) to operate on the file without decrypting it. I'm pretty sure that this has nothing to do with permissions. Homomorphic encryption maintains certain properties of the plaintext (through some isomorphism) to allow pre-defined operations (operations that the isomorphism are designed for). Also, why theregister? Why not link to the actual article (http://eprint.iacr.org/2011/277 http://eprint.iacr.org/2011/277) or the github project (https://github.com/shaih/HElib https://github.com/shaih/HElib) They're much, much more informative.

The Register article is much easier to read as a news piece, especially for people unfamiliar with encryption algorithms. Besides, the article includes links to more technical materials, including the project page should the reader want to find out more.

  It's cases like this where it would be useful to be able link to multiple articles at once (to avoid possible blogspam appearing as the intermediary).

    Destructuring links? I'm sure Ted Nelson specified those somewhere.

      Is that a Xanadu term? Looks like a "google whack" at my end at the time of posting: http://www.google.com/search?q=%22destructuring%20links%22 http://www.google.com/search?q=%22destructuring%20links%22

        I was semi-joking. I would not have been surprised in the least if he had invented them at some point. Between him and Alan Kay, you've got about 90% of everything covered. :-)

I've read 'permitted' as 'operations that can be performed on the ciphertext when using this encryption scheme'. While it might be ambiguous, I don't think they're incorrect in saying that.

If it's on The Register then they almost certainly don't understand the source material.

Regardless of whether they were right, I really appreciate that they added the "... – if The Register understands the paper correctly – ..." clause. So many technical articles just get the facts wrong and pass them off as correct. I appreciate the honesty in this case.
