Electronic Lockers
The cost of securing electronic lockers, safes and other small compartments multiply quickly when the number of
individual units is large. Solutions using the AT88SA102S CryptoAuthentication device now make securing many
individual units or areas with many zones very affordable. The optional addition of the AT88SA10HS device can be
used on the host side to make the lock both very secure and very inexpensive. Figure 10 displays the
AT88SA10HS/102S devices being used to secure electronic locking applications.
Figure 10.
The customizable aspect of the AT88SA102S uses unique serial numbers in each device along with 62 bit customer
implemented secrets and a 265 bit secret key. This enables each locker produced to have a unique worldwide keying
combination, eliminating any possible overlap or key combination reuse as often occurs in tumbler lock solutions.
Master lock keys could also be produced for a set of units or product line. The incrementally burnable keys could be
used to implement a per use payment structure or to render keys unusable after a preset number of usages.
