      Title: Recent Topics on Authenticated Encryption Algorithms

      An authenticated encryption algorithm is a symmetric primitive that
      performs both confidentiality and integrity, which has been widely
      recognised as giving higher security and efficiency than simply
      combining individual two primitives, encryption and MAC. Currently
      "CAESAR" the US NIST-funded international open competition is running
      for establishing consensus of authenticated encryption algorithms.
      In this talk, we first introduce authenticated encryption with its
      background and existing algorithms, and then discuss some security
      issues, particularly focusing on misuse scenarios. We also talk about
      our recently developed authenticated encryption algorithm.
