What are the security and privacy implications of
these trends?
• Privacy – companies know a lot about us
• Data security – a security breach exposes all
our data
Confidential data in the cloud
13. 03
Encrypt data while it is
stored on cloud servers
– but then how can they do
any useful computation on
our data?

25. 05 Case Study
Centralized Trust 3rd Parties lets you store your
private data in their storage.
– Certificate Authority(or bank and etc) has ‘master key’ so
can decrypt all your data.
– A bug or security breach in C.A can expose all your data.
– Suffer possible corruption of 3rd parties
26. 05 Case Study
DropBox lets you store your files in the cloud.
• For efficiency reasons, if 2 or more members have the
same file , DropBox doesn’t want to store it twice.
• For security reasons, it’d be nice if DropBox could encrypt
your files on your computer (with a key only you know) and
upload the encrypted version.
• In fact, on 6/19/2011, DropBox did have a bad bug, where
they screwed up the authentication: you could log into
someone else’s account without knowing their password (just
enter any password, and you’re in). This exposed everyone’s
files to the world.
