A smart electronic lock is an electronic lock, which has a programmable interface to set up different PINs or passwords for the smart lock, duration of these PINs/passwords, some rules, etc. and do not use keys, magnetic cards or other physical objects as keys.
For the reason that users do not need to carry keys, magnetic cards, etc., smart locks offer better convenience and security for the users.
If the PINs/passwords are not stored in any physical place, for example virtual PINs/passwords, then they can not be hacked, damaged, stolen, confiscated, etc. This gives the users a very high degree of security.
In this post we consider a simple way to manage multiple smart electronic locks, in a very secure manner, by using private dynamical passwords generators (DPGs see [1-8]).
Example 1.
Helen is a manager of a hotel. She manages 100 rooms, which have smart electronic locks, for visitors. Each day she needs to create 100 temporary PINs/passwords for maidens, valid for this day, only and also temporary PINs/passwords for visitors, with durations equal to their periods of staying in the hotel. If Helen keeps all PINs/passwords on a paper or electronic device then this creates a security risk for the hotel. Instead, Helen uses a private DPG, which generates 100 unique, super strong passwords, with a single click. Each day, she generates passwords with the DPG, using her key and the current date, and sends 100 unique, super strong passwords, via encrypted emails to maidens and also generate passwords for those who check-in into the hotel. Then Helen securely deletes all sent emails from the “sent” folder. Now, if hackers will be able to hack Helen’s computer then they will not be able to find the passwords/PINs on it.
Example 2.
Mary is a manager of 100 rental units in a residential complex. The units have smart electronic locks. Each day she needs to create temporary PINs/passwords for renters, contractors and maintenance staff, with durations equal to their period of staying in the residential complex. If Mary keeps all PINs/passwords on a paper or electronic device then this creates a security risk for the residential complex. Instead, Mary uses a private DPG, which generates 100 unique, super strong passwords, with a single click. Each day, she generates passwords with the DPG, using her key and the current date, and sends unique, super strong passwords, via encrypted emails to the renters, contractors and maintenance staff. Then Mary securely deletes all sent emails from the “sent” folder. Now, if hackers will be able to hack Mary’s computer then they will not be able to find the passwords/PINs on it.
Example 3.
Mike is a manger of a warehouse, which has 100 locked rooms and serves 500 businesses and government organizations. Each day, people from these businesses and organizations need access to 100 rooms, which have smart electronic locks. The security policy of the warehouse requires to change all passwords to all rooms, each day. Mike gives to each person (a representative of a business or organization) a private DPG to generate passwords for 100 smart electronic locks. Each day, he generates 500 keys for representatives, with his private DPG using his key and the current date, and sets up the smart locks passwords for the current day as passwords generated by representatives’ private DPGs. Mike sends these 500 keys, via encrypted email to the representatives. Then Mike securely deletes all sent emails from the “sent” folder. Now, if hackers will be able to hack Mike’s computer then they will not be able to find the keys to representatives’ private DPGs on it. The representatives use the received keys and the current date as input parameters to their private DPGs and can generate passwords for all (100) rooms having smart electronic locks, with a single click.
Example 4
Alexandra is a manager of 100 safe deposit boxes in a bank. The safe deposit boxes have smart electronic locks. The bank’s security policy requires to change PIN/passwords to the security boxes each week. Each week, Alexandra needs to create temporary PINs/passwords for deposit boxes owners, with durations equal to one week. If Alexandra keeps all PINs/passwords on a paper or electronic device then this creates a security risk for the bank. Instead, Alexandra uses a private DPG, which generates 100 unique, super strong passwords, with a single click. Each week, she generates passwords with the DPG using her key and the current date, and sends unique, super strong passwords, via encrypted emails to the owners of the deposit boxes. Then Alexandra securely deletes all sent emails from the “sent” folder. Now, if hackers will be able to hack Alexandra’s computer then they will not be able to find the passwords/PINs on it.
Example 5
Peter is a manager of 100 laundries in a city. The laundries have smart electronic locks. Each day, he needs to create temporary PINs/passwords for users and maintenance staff, with durations equal to one day. If Peter keeps all PINs/passwords on a paper or electronic device then this creates a security risk for the Peter’s company. Instead, Peter uses a private DPG, which generates 100 unique, super strong passwords, with a single click. Each day, he generates passwords with the DPG using his key and the current date, and sends unique, super strong passwords, via encrypted emails to the users and maintenance staff. Then Peter securely deletes all sent emails from the “sent” folder. Now, if hackers will be able to hack Peter’s computer then they will not be able to find the passwords/PINs on it.
Example 6
John is a manger of a e-bike sharing company, which has 1000 e-bikes, secured by smart electronic locks, in 100 locations. The security policy of the company requires to change all passwords to all smart electronic locks, each day. John gives to each customer a private DPG to generate passwords for 100 smart electronic locks in 100 locations, so that each customer can access an e-bike in each location. Each day, he generates keys for customers, with his private DPG using his key and the current date, and sets up the smart locks passwords for the current day as passwords generated by customers’ private DPGs. John sends these keys, via encrypted email to the representatives. Then John securely deletes all sent emails from the “sent” folder. Now, if hackers will be able to hack John’s computer then they will not be able to find the keys to customers’ private DPGs on it. The customers use the received keys and the current date as input parameters to their private DPGs and can generate passwords for smart electronic locks in all (100) locations, with a single click.
