Alice's Birthday Party (Part 2) Level 2

by Lehrstuhl für Kryptologie u. IT-Sicherheit, Ruhr-Universität Bochum, published on 2010-10-14

Alice has learned from her mistake from last year. This year, she makes sure that the friends to whom she sends invitations for her birthday party all use unique RSA N parameters. However, this time she still makes another mistake that allows an adversary, Eve, to reconstruct the message. Can you again decrypt this year's invitation? The codeword for this challenge is the location of Alice's party.
