Cryptography prior to the modern age was effectively synonymous with encryption, the conversion of information from a readable state to apparent nonsense. The originator of an encrypted message shared the decoding technique needed to recover the original information only with intended recipients, thereby precluding unwanted persons to do the same. Since World War I and the advent of the computer, the methods used to carry out cryptology have become increasingly complex and its application more widespread.

Chris Peikert of Georgia Institute of Technology presented a talk titled: Lattice cryptography for the internet at the 2014 PQCrypto conference in October, 2014.
Abstract: In recent years, lattice-based cryptography has been recognized for its many attractive properties, such as strong provable security guarantees and apparent resistance to quantum attacks, flexibility for realizing powerful tools like fully homomorphic encryption, and high asymptotic efficiency. Indeed, several works have demonstrated that for basic tasks like encryption and authentication, lattice-based primitives can have performance competitive with (or even surpassing)

Abstract: In recent years, lattice-based cryptography has been recognized for its many attractive properties, such as strong provable security guarantees and apparent resistance to quantum attacks, flexibility for realizing powerful tools like fully homomorphic encryption, and high asymptotic efficiency. Indeed, several works have demonstrated that for basic tasks like encryption and authentication, lattice-based primitives can have performance competitive with (or even surpassing) those based on classical mechanisms like RSA or Diffie-Hellman. However, there still has been relatively little work on developing lattice cryptography for deployment in real-world cryptosystems and protocols.
In this work, we take a step toward that goal, by giving efficient and practical lattice-based protocols for key transport, encryption, and authenticated key exchange that are suitable as "drop-in" components for proposed Internet standards and other open protocols. The security of all our proposals is provable based (sometimes in the random-oracle model) on the well-studied "leaning with errors over rings" problem, and hence on the conjectured worst-case hardness of problems on ideal lattices (against quantum algorithms).
One of our main technical innovations (which may be of independent interest) is a simple, low-bandwidth reconciliation technique that allows two parties who "approximately agree" on a secret value to reach exact agreement, a setting common to essentially all lattice-bases encryption schemes. Our technique reduces the ciphertext length of prior (already compact) encryption schemes nearly twofold, at essentially no cost.

A gentle introduction to elliptic-curve cryptography
This talk will explain how to work with elliptic curves constructively to obtain secure and efficient implementations, and will highlight pitfalls that must be avoided when implementing elliptic-curve crypto (ECC). The talk will also explain what all the buzz in curve choices for TLS is about. This talk does not require any prior exposure to ECC.
ECC is rapidly becoming the public-key technology of choice for Internet protocols. ECC was introduced in 1985 and has a much stronger security record than RSA. ECC research has found new ways of attacking implementations but has also found nicer curves that avoid such attacks.
As a followup to the Snowden revelations, the TLS working group of the IETF has recently asked the crypto research group (CFRG) to suggest new curves for use in TLS, and NIST has publicly announced that they are considering new curves.
This talk gives a hands-on description of how to compute with elliptic curves. It shows different ways to write elliptic curves and the consequences of this representation for secure and efficient implementation. Algorithms will be presented as Python code snippets and will already be online before the talk at http://ecchacks.cr.yp.to.
The talk will be given as a joint presentation by Daniel J. Bernstein and Tanja Lange.
