Cryptography after Quantum Computation

Due to Shor's algorithm and the imminence of quantum computers, all cryptographic standards are being rethought. In this talk, we address a security functionality associated with privacy, namely oblivious transfer. We present some cryptographic solutions proposed within the Security and Quantum Information Group at Instituto de Telecomunicações. Specifically, we discuss the proof of security for methods based on quantum information (quantum cryptography) and for classical methods, based on hardness assumptions conjectured to be robust to quantum attacks (post-quantum cryptography). We conclude by examining the advantages and disadvantages of each approach, as well as their implications in cryptography and technology.

Colloquium_logo

The Mathematics Colloquium is a series of monthly talks organized by the Department of Mathematics of IST, aiming to be a forum for the presentation of mathematical ideas or ideas about Mathematics. The Colloquium welcomes the participation of faculty, researchers and undergraduate or graduate students, of IST or other institutions, and is seen as an opportunity of bringing together and fostering the building up of ideas in an informal atmosphere.
