Researchers' scheme allows encrypted and shareable Google Docs

Yet more cloud based encryption research. Researchers at Trinity College, Dublin are reported by The Register to have developed software providing "'real-time' encryption of data before it is uploaded to the Google servers". The CipherDocs project also goes beyond simple document encryption. It preserves Google Docs ability to let users share their documents, thus allowing the secure sharing of encrypted Google docs transparently. It is also secure in the sense that Google would not have access to the encryption keys.
