How practical are side-channel attacks and how much of a concern are they? @FrancisW.Usher, that was definitely something I had thought about. I think it can be answered if someone knows the industry well enough. If most of the vendors out there are worried about this stuff and putting protections in their products, then there is good reason to believe that the attacks are possible (as the protections only add to cost, etc). We'll see, right. |

Security considerations for partially shared password databases @uosɐſ, I re-opened this question and closed the other as you requested. Since there were answers on the other, I have merged the two so that the answers would show up here. |

Bitcoin Research Would you mind rewording your question some? I'm having a hard time figuring out what you are asking. As worded you are asking if anyone knows of any research that is or has been done. The answer to that is clearly yes, someone does know of research that is/has been done. Are you wanting a list of research areas within the bitcoin realm that relate to cryptography? Is there something specific that a simple search of "bitcoin" on google scholar is not turning up that you are interested in? |

Why does ROT13 provide no cryptographic security? Get the plaintext from the statistical analysis, then look at the substitution table used to get the plaintext. It will be very obvious. If you mean by only looking at the ciphertext, that would be hard to tell that it was the ROT13. You could, however, tell it was a simple substitution cipher by only looking at the ciphertext, but without further analysis, you couldn't recreate the substitution table. |
