  1. Remote Access and Proximity Key InteLockTM Advisor: Professor Ganz Team: Emmanuel Seguin Christos Tsiokos Josh Coffin Anh-Kiet Huynh

  2. Background & Motivation • Getting into the front door of one’s home can present a troublesome situation • Fishing around in pockets for keys • Finding the correct key to unlock the door • Problems arise when it is dark outside • Loss or misplacement of keys • Inconvenient to find keys when hands are tied up

  3. Background & Motivation • Various keyless entry systems have been developed • Combination Lock • Gain entry into a home by inputting preset code into door keypad

  4. Background & Motivation • Remote Door Lock • Gain access to home utilizing a small remote device similar to that of a keyless car remote • Electronic Card Key Lock • Gain access to home utilizing an electronic card key • Electronic card key must be placed over card reader • Door unlocks if proper card key is in place • Some locks require sliding of key

  5. Background & Motivation • Fingerprint Identification Lock • User places finger in fingerprint identification scanner • Scanner checks for record of the fingerprint • Allows access through door if fingerprint matches records

  6. Background & Motivation • All products are great alternatives • Each individual keyless system provides its own unique security protocols • Cost can be a huge downside

  7. Background & Motivation • Another alternative to keyless entry systems • Propose a new product designed for residential population • Easy to use, easy to install • Will fit in existing doors in the home • Ability to be upgradeable (i.e. new security features) and expandable (i.e. home automation, lighting controls, temperature controls, etc) • Low power consumption

  8. Background & Motivation • What’s the plan? • Homeowner with a special electronic key will be able to access door (discussed in detail later) • Utilize wireless devices that operate on cell, AA, AAA batteries • Wireless device will operate for years without having to constantly change batteries • Wireless devices must be small for easy integration into existing door • User keys must also contain small wireless devices

  9. Background & Motivation • Additional features • How to overcome the misplacement or loss of electronic key? • Each key has a unique ID tag • Can set system so that the loss ID tag will not be accepted • Integrate keyless system with internet • Home entry control from remote location

  10. Requirements • Phase (1) will involve the interaction of the parts: doorknob, access key, deadbolt and coordinator • Phase (2) will involve interaction between a PC and coordinator of phase (1), and a http web site

  11. REQUIREMENTS Phase (1) • Zigbee is used for any wireless interaction • Door unlocks in presence of a valid key when Door Knob is turned • Independent and wireless units run on batteries • Quick system response

  12. Requirements (Phase (1)) • The key has a practical size • Encryption (AES-128) • Doorknob turning tolerance will be about 20 degrees

  13. REQUIREMENTS Phase (2) • Phase (1) interfaces with phase (2) • The system connects to the internet • Access through a http web site • User controls the door and checks its status

  14. Design Characteristics • Water fall method • Component Based • Design Simplicity • Expandability • User Friendly

  15. Door Knob Trigger:

  16. Electronic Deadbolt • Existing electric deadbolt • New microcontroller • Existing power supply

  17. Software Developement • Phase I • WinAVR Development Environment • Familiarity with environment • Familiarity with command structure and library • C++ embedded software • Phase II • Text Pad Java D.E. and compiler? • Familiarity • M.S. Visual Studio? • Graphic Objects

  18. Design Alternatives for Technology

  19. Design Alternatives for ZigBee Technology Development Kits

  20. Deliverables: -Phase I (1) Command unit (1) Door knob (1) Deadbolt (2) Keys Associated Source Code User Manual -Phase II Server Software for PC Source Code Interface between PC and Control unit User Manual Deliverables and Demo Tests • Acceptance Tests: • -Phase I • Door must unlock only • if valid Key is within range • Deadbolt must disengage within 1 second • of knob turning • -Phase II • Software must be active whenever PC is running • Interface must only allow authorized users • to operate the system

  21. Proposed MDR Specifications • Psuedo-code for embedded firmware on each system components • Establish communication between ZigBee coordinator and at least one node • Generate associated documentation • Assemble and test trigger mechanism for Door Knob
