Applied Cryptography Group

The Applied Crypto Group is a part of the Security Lab in the Computer Science Department at Stanford University. Research projects in the group focus on various aspects of network and computer security. In particular the group focuses on applications of cryptography to real-world security problems.

Lattices in Cryptography

Integer lattices have found many applications in cryptography: in proofs of security, in attacks, and in constructing cryptosystems.

Privacy

Can multi-user services operate without sending all user data to the cloud in the clear? Some examples include private location-based services, private computation of aggregate statistics, private recommendation systems, private queries to a database, and anonymous messaging.

Blockchain technologies

We are developing cryptographic tools with applications to blockchains. We are also teaching a course on the topic, CS251.

Pairings-Based Cryptography

Cryptographic pairings have numerous applications to cryptography, including everything from identity-based encryption and short digital signatures to broadcast encryption and search-friendly encryption.

Computer and Web Security

Computer security research explores architectures that improve software security and enhances our understanding of attack strategies. Our research covers SSL and TLS, Web security, and areas of operating systems security.

Projects



Export Control Warning: The US Government regulates the physical export or transmission of cryptographic source and corresponding object code outside the borders of the US and within the US when the recipient is an embassy or an affiliate of a foreign government. Posting encrypted code to the internet and making it publicly available is considered an export and may entail US government notification requirements. Please see Stanford's Export Control Encryption Page if you have a need to take, transfer or transmit Stanford-generated encryption code outside of the US or to share it with US-based representatives of foreign governments.
