Here's a brief abstract for tomorrow's talk.

Title: Quantum asymmetric-key encryption schemes

One of quantum information's biggest contributions to cryptography is unconditional key distribution and its consequences for symmetric cryptosystems. Asymmetric-key encryption schemes are however widely spread in the classical world, and have some practical advantages over symmetric schemes, although they only offer computational security.

We explore quantum asymmetric-key encryption schemes, i.e., schemes which make use of a quantum state as encryption key, and allow the encryption of classical or quantum messages. We focus on information-theoretical security and discuss issues such as the (dis)advantages over classical schemes, optimality, security, message/key ratio.

See you tomorrow

Dear All,

Next weeks research day on Tuesday will be at the Electrical Engineering Builidng, room ETF C109. The room will be opened at 9:30 am by Patrick so we can work there the whole day.

The talk is given by Christopher Portmann at 5:00 pm.

Cheers,
