For centuries, secure communications were mainly the domain of secret services, diplomats, and the military but today cryptography and secure communications are enabling technologies without which activities like electronic commerce cannot flourish.
The current challenges are manifold. On the practical side, more powerful cryptography has to function on less powerful devices, such as mobile implements, in ad-hoc or peer-to-peer networks, on smart cards or RFIDs. On the theoretical side, the current requirement for cryptographic proposals is that they come with a security reduction, showing that a break of the system implies the efficient solution of a standard computational problem that is not supposed to have one. The tasks here include general constructions that put several secure components together and still are secure, and applications of this technology in areas such as biometry and steganography. Elliptic curves have emerged as a central tool in modern cryptography. Their practical applications, including pairings for identity-based encryption, are still amenable to many improvements.
