Re: [PLUG] Sensitive Personal Information In the Cloud? Why bother?

That is precisely Greg's point, I think: encryption is only useful in the present and near-term, since Moore's law implies that cracking present encryption standards will be trivial at a later date. At said later date, you should be using stronger encryption. See this thread:

If you can hold onto encrypted data for long enough, you'll be able to decrypt it. How large of a problem that poses for Alice and Bob depends on how much computing power you have to throw at the problem, as well as how useful the decrypted content will be at the later date.

This does seem like a quandry for long-term storage of encrypted data - if an adversary obtains the encrypted data, it is not secure against future compromises of the encryption scheme, which obviates the benefits of encryption over time. Thoughts?

This is a biggie, IMO.  The encryption considered very safe today could be trivial to crack 20 years from now.  If you wouldn't want the things you encrypt today being public 20 years from now, maybe cloud storage isn't the best choice.

That being said, right now, we have no idea how long cloud
storage will last or what factors might affect the security of things
encrypted and then stored in the cloud.  The encryption method we use
today may be proved vulnerable a month, two months or years from today.
