Definitions

  • the invention relates to installations for command and control of the different coded locks of an assembly comprising a relatively large number of such locks, this number preferably being greater than 50 and even more than 100.
  • the coded keys in question are preferably cards carrying a code recorded in magnetic or optical form, or even portable transmitters of codes in the form of electromagnetic or ultrasonic waves, and the codes considered are numbers expressed by sequences binary signals.
  • the coded keys may also consist of an intangible code intelligibly entrusted to an authorized user, for example in the form of a series of numbers and / or letters, and intended to be composed on a keyboard arranged near the lock or to be reproduced in any other desirable manner.
  • the code assigned to each key by a central key transmitter comprises two portions recorded respectively on two distinct areas of the key, namely a first portion directly assigned to unlocking the lock and a second portion assigned to the code change.
  • first key a key entrusted to a first user authorized to unlock a given lock
  • second key a key entrusted subsequently to a second user whom we wish to empower in turn by deleting the 'authorization of the first
  • the code portions recorded by the central key transmitter on the two ranges of the first key will be designated by A and B respectively and by B' and C the code portions recorded respectively on the two ranges of the second key.
  • the lock concerned originally comprises means for controlling its unlocking on reading the partial code A on the first range of a key, means for storing the partial code B carried on the second range of such a key carrying the partial code A on its first range, and means of comparison.
  • the reading of the partial code A of its first range directly ensures the unlocking of this lock and the partial code B only intervenes by its storage.
  • the unlocking section of the lock no longer reads the correct partial code A on the first range of this key, but the partial code B.
  • comparison means of the lock come into play: these compare the partial code (here B) previously stored in memory coming from the second range of the first key with the new partial code read on the first range of the second key.
  • the identification resulting from such a comparison has the effect of unlocking the lock, of making this lock adopt the code thus identified, that is to say here the partial code B, as the new unlocking code and of invalidating , by erasure or otherwise, the partial code A of initial unlocking.
  • algorithm is meant in the present text a set of numerical operations corresponding to a first number x a second number y.
  • Each of the transmitter and reader devices is then equipped so as to exploit the algorithm appropriately.
  • the transmitter working out the successive keys intended to unlock the lock equipped with the reader in turn is arranged so as to register respectively on these successive keys the codes x, f (x), f 2 (x) ... f (x) ...
  • n denotes an integer
  • f means f [f n ⁇ 1 (x)] and the symbol f (x) is equivalent to f (x).
  • the reader associated with the lock considered it is arranged so as to compare successively the codes read on the different keys with the codes x, f (x), f 2 (x), ..., f "(x). .. and unlock the lock when the comparison reveals an identity.
  • the reader is equipped with means for automatically invalidating each code fP (x) when the key bearing the code f p + 1 (x) is presented to it.
  • each reader-lock sub-assembly is arranged in such a way that at a given moment the lock can be unlocked by presenting to the reader one or the other of two codes f (x) and f P +1 (x), the presentation of the first of these two codes resulting in the only unlocking of the lock while the presentation of the second code results not only in this unlocking, but also in the invalidation of the first code and in the making the reader aware of the following code f p + 2 (x) of the series, the roles played respectively just before this presentation of the second code fP +1 (x) by the first two codes being played respectively from this instant by the two codes f P +1 (x) and fP + 2 ( x ) .
  • each reader is sensitive at each instant to only two codes, namely the codes fP (x) and f +1 (x) in the example above.
  • the invention overcomes this drawback.
  • each reader is made sensitive at all times to a number m greater than two of non-invalidated codes of the sequence of codes f P (x), f p + 1 (x), f p + 2 (x). deductible from each other by the algorithm f (x).
  • This reader is then arranged in such a way that by reading any of the valid codes of this sequence, it automatically invalidates all the codes of lower rank of said sequence.
  • the lock associated with said reader can be opened at any time by the last key produced by the transmitter intended for this lock.
  • the number m is chosen according to the real risk presented by the defect indicated above: it is preferably between 5 and 100, being for example of the order of 10.
  • the different codes of the suite in question can be recorded in advance in a memory of the reader concerned, the number of these valid codes gradually decreasing due to the successive invalidations of the keys.
  • the reader can be equipped with means for counting and recording the number of code changes which have occurred since the origin of the life of the lock or since a determined instant of reset.
  • the appropriate code sequence can be saved as previously in a memory of each reader: the identification of the first code, of this sequence, valid at a given time can then be obtained by simple counting, mentioned above. above, the number of code changes that have occurred since a given start time, which may be a reset time, counting of course supplemented by knowledge of the start code assigned to the lock concerned.
  • This simplification is very important since, for example for the application of the invention to the service of a hotel with 100 rooms, it amounts to dividing by 100 the number of algorithms recorded in the transmitter as well as the number of circuits corresponding calculation and transformation.
  • the installation proposed here overcomes the servitudes of "synchronization between the transmitter and the readers, the absence of use of certain" first keys "does not more reflected here by the neutralization of the “corresponding second keys.
  • the invention is in no way limited to those of its modes of application and embodiments which have been more especially envisaged; it embraces, on the contrary, all variants, in particular those where the algorithm allowing to develop the code y from the previous code x would be a function not only of this previous code, but also of a number assigned to the set lock-reader concerned, number recorded both in this set and in the transmitter, in particular in the case where the number of said sets is particularly high.
