  1. Authentication paramount practices in wireless networks By: Ahmad Almadhor and Aaron Black

  2. Reasons for authentication • To prevent unwanted users from gaining access to the network • i.e. Only paying members should have access • Ensure network integrity • i.e. Only teachers can see grades • Protect vital information • i.e. Medical records, Legal records

  3. Goals for authentication scheme • It should be efficient • memory • financial cost • processor consumption • Centralized v.s. Decentralized structure

  4. Current Ideas • Distributed Authentication • Remote Passwords • LEAP+ • Broadcast Authentication • And many more

  5. Distributed Authentication • Focuses on collectively storing authentication information • Uses tokens to store and pass authentication information • Designed to reduce cost by moving away from a centralized approach

  6. Remote Passwords • Uses Secure Remote Password (SRP) protocol with concepts from Simple Authentication for the Web (SAW) • It is decentralized

  7. LEAP+ • Uses four types of keys for each sensor node • Computational cost is desirable • Storage requirement is efficient

  8. Broadcast Authentication • Computational and communication cost minimized • Four Public Key Cryptography PKC schemes proposed in paper • Certificate-Based • Merkle Hash Tree • Enhanced Merkle Hash Tree • ID-Based

  9. Our Contribution • Proving the more efficient authentication approach that is available recently. • Scrutinize such mechanisms feasibility or investigating it. • As of right now we are still gathering information • Will be displayed in final presentation
