HLPSL

A Provably Secure and Lightweight Anonymous User Authenticated Session Key Exchange Scheme for Internet of Things Deployment

Agents involved: A, B and C

  • A : User
  • B : Server/GateWay Node(GWN)
  • C : Sensor

Stages:

  1. Notations: Image description

  2. Registration

    • User → GWN
    • GWN → User
    • Sensor → GWN
    • GWN → Sensor Image description

  3. Login and authentication phase.

    • User → Sensor Image description

We focus on designing a new lightweight user authentication protocol suited for IoT architecture, which will also achieve anonymity and untraceability. We have implemented the following phase :

1) User Registration Phase

2) Login and User Authentication Phase

Roles:

  1. user ( A, B, C : agent, H : hash_func, S,E,D: symmetric_key, SND, RCV : channel(dy) )

    • User Registration
    • User receiving smard card from server with password
    • User ssending login request to server
    • User receiving message from smart device

  2. sensor ( A, B, C : agent, H : hash_func, S,E,D: symmetric_key, SND, RCV : channel(dy) )

    • Device sends message to user

  3. server ( A, B, C : agent, H : hash_func, S: symmetric_key, SND, RCV : channel(dy) )

    • Server receives RID for registration and send smart card to user
    • sensor request to server to authenticate that the data received is from assumed user

Goals:

  1. Secrecy of random nonces are maintained
  2. Authentication is secure
