In this paper, we present a passive attack for finding out the secrets used in MAP (Minimalist Mutual Authentication Protocol), which is an authentication protocol between RFID tags and RFID readers. We describe an algorithm that breaks the protocol after eavesdropping a few consecutive rounds of communication. After two eavesdropped runs of the protocol, the attacker can learn the identificati...

They were not to be touched under any circumstances ; they held the secrets of life and death and for that reason were sacred in the sight of God. So it was that for two ...

The visual secret sharing (VSS) scheme encrypts the secret information into various meaningless shares. These shares are distributed to the authorized participants and the secret information can be retrieved by any k out of n participants by stacking their respective shares on top of each other. This scheme uses HVS (Human Visual System) to decrypt the information, and thus no technical or fina...

The results of two experiments performed over a period of four semesters demonstrate the benefits of active and cooperative classroom activities. The insights and methods provided by Project LEA/RN (Learning Enhancement Action/Resource Network) discussion groups at Iowa State University have demonstrably improved student learning in engineering classrooms. Reversing the typical roles of lecture...
