Cryptography (or cryptology; from Greek κρυπτός, "hidden, secret"; and γράφειν, graphein, "writing", or -λογία, -logia, "study", respectively) is the practice and study of techniques for secure communication in the presence of third parties (called adversaries). More generally, it is about constructing and analyzing protocols that overcome the influence of adversaries and which are related to various aspects in information security such as data confidentiality, data integrity, and authentication. Modern cryptography intersects the disciplines of mathematics, computer science, and electrical engineering. Applications of cryptography include ATM cards, computer passwords, and electronic commerce.
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.

ECCHacks 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 fou -

Henry is a Ph.D. student at Stanford working on cryptography under Dan Boneh. His research has included work on Riposte, an anonymous messaging system for millions of users.

ECCHacks
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.
