SMART SECURITY MANAGEMENT SYSTEM

ELECTRONICS AND COMMUNICATION ENGINEERING

A smart lock is an electromechanical lock which is designed to perform locking and unlocking operations on a door when it receives such instructions from an authorized device using a wireless protocol and a cryptographic key to execute the authorization process. It also monitors access and sends alerts for the different events it monitors and some other critical events related to the status of the device. Smart locks can be considered part of a smart home. Most smart locks are installed on mechanical locks and they physically upgrade the ordinary lock. Smart locks, like the traditional locks, need two main parts to work: the lock and the key. In the case of these electronic locks, the key is not a physical key but a smartphone or a special key configured explicitly for this purpose which wirelessly performs the authentication needed to automatically unlock the door. Smart locks allow users to grant access to the key to the lock by means of a virtual key. Basic infrastructure requirements with wireless locking are very low. There are no additional server function requiremements beyond public key infrastructure standards. Major advantage with wireless locking comes with automating log-off. Hence common lacking of caution by mobile users may be entirely compensated. Automatic wireless authentication factors do not require any handling. The only requirement to the user just to wear a token without any keying is unsurpassed in comfort and functional value. Wireless locking provides additional security for networks against fraudulent access and usage. Wireless locking offers best robustness against de-authentication attacks. Continuous connection based encrypted key exchange between active token and receiver dongle provides a sufficient security level prepared for certification under ISO/IEC 15408 common criteria specification. Initially connection based encrypted key exchange serves for a lower security level which appears sufficient for most requirements.
