Definitions

  • the invention relates to lock devices electrically controlled by means of a dematerialized and encrypted key, this key being able to be conveyed by a portable object held by the user such as a magnetic card, a smart card, a badge or a card. contactless card, etc.
  • lock device is meant not only a lock stricto sensu, that is to say a mechanism placed for example on a door to condemn the opening, but also any device to achieve a comparable result, for example a lock gun considered in isolation, or a more specific locking device comprising various members not grouped in the same lock box, the ultimate goal being to obtain the conviction by mechanical means of physical access to a place or given space, and access to this place or space by unlocking the lock device, on the order of a user, after verification that this user has access rights (i) that are specific to him and (ii) who are specific to the lock device.
  • the lock device may also include, or be associated with, an alarm system that is to disable to allow access to a given space, or conversely activate to protect this space before or after the to have left.
  • the portable object when approached from the lock, acts as a key for ordering the opening by means of a given hereinafter "certification” (credential).
  • certification credential
  • Various coding and encryption techniques can be implemented in the lock and / or in the portable object to provide protection against fraudulent manipulations and secure communication between the portable object and the lock.
  • Numerous magnetic card systems are known, or cards or badges with microcircuit implementing with the lock a galvanic coupling (smart card contacts) or non-galvanic (inductive coupling card or RFID type card). This coupling ensures between lock and badge communication allowing in particular the lock to read in the memory of the badge accreditation data to control the opening if this data is recognized as compliant.
  • the US 5,933,090 A discloses such an unlocking system controlled remotely and without physical contact, by a specific object dedicated to the opening of the particular type of lock considered.
  • Another drawback is related to the variety of techniques used, each manufacturer having its own specifications both at the level of the physical layer (technological choice of coupling: inductive, RF, magnetic, galvanic, etc.) at the level of format of the data and protocols for exchanging this data between the reader and the portable object.
  • This variety of techniques linked to technological choices and implementations specific to different manufacturers, is a brake on interoperability, the standardization of materials and procedures and technological evolution, which prevents the rapid spread of these techniques, despite their indisputable advantages.
  • the system is a fixed system, because if one wishes to update the authorizations, to delete existing authorizations or to create new ones, it is necessary either to proceed to the exchange of the portable object, or to update the memory of the latter by means of a protocol and / or a specific reader, with the need for physical manipulations and displacements.
  • One of the aims of the invention is to propose an alternative technique of management and control of locks that can complement the existing techniques, or even replace them, without requiring substantial changes in both hardware and software, and which offers a maximum level of security, a great flexibility of implementation and is usable without recourse to a specific portable object.
  • the technique of the invention can be used by means of any conventional mobile phone serving the portable object carrying the key to control the lock, without the user needs to use a specific and dedicated portable object, such as a badge or card.
  • the WO 03/093997 A1 proposes an access control system controlled by a universal device available to the user, such as a digital assistant (PDA) or a mobile phone.
  • PDA digital assistant
  • the system, and especially the locks, must however be designed specifically to be controlled by a device of this type.
  • the technique of the invention differs from this document in that it will allow to adapt without major modification the existing locks, without having to replace the hardware elements or software already integrated at the lock. It will be seen that the invention is perfectly compatible with the pre-existing techniques implemented by the various current manufacturers, insofar as it limits the intervention to a single layer of the communication protocol (the transmission of the accreditation to the lock), thus maintaining the same logical management of the different levels of security already provided by the manufacturer.
  • the principle of the invention is based on the use, for the transmission of the accreditation data to the lock, encrypted acoustic accreditations type information.
  • acoustic accreditations are for example in the form of a coded series of tones (DTMF tones or other), emitted by the speaker of a transmitting device and picked up by the microphone of a receiving device.
  • DTMF tones coded series of tones
  • the present invention consists in translating, at the level of a secure site, the conventional accreditation used for access management (a data block comprising a manufacturer's identifier, a unique identifier of the lock and possibly additional information ) and translate them into an encrypted acoustic accreditation format.
  • This acoustic accreditation is in the form of an audio signal that can be conveyed by audio transmission channels, including telephone transmission channels, and reproduced as such by acoustic transducers.
  • the acoustic accreditation is sent in this manner to the mobile phone of the user, which is listed in a database of the secure site.
  • the user approaches his phone lock and triggers the transmission by the speaker of his phone in the series of tones corresponding to encrypted acoustic accreditation, so that these tones can be captured by a microphone incorporated or coupled to the lock.
  • the latter operates a translation inverse of the acoustic accreditation allowing to restore the original format of the conventional accreditation, which is then applied to the circuits of the lock to be treated in the same way as if this accreditation had been read by a standard reader coupled to the lock (magnetic or smart card reader, inductive coupling reader or RFID, etc.).
  • This document describes a technique for securing logical access to a computer network by a remote terminal, for example by a computer connected to this network via the Internet.
  • the user connects to the network with his computer, simultaneously lights his mobile phone, and calls through it a control site interfaced with the network to which access is requested.
  • the network sends a sound signal (Acoustic Accreditation) to the remote computer that has just connected, a signal that is reproduced by the speaker of the computer.
  • This sound signal is picked up by the telephone, transmitted to the remote control site via the mobile telephone network operator and "listened to" by the control site, who can then check accreditation and authorize access to the computer network by the terminal.
  • the acoustic accreditation is captured by the microphone of the phone which retransmits it to the control site. Knowing the recipient of the phone call, the control site can identify the user through the mobile phone used for this operation, and thus allow logical access to the network by the terminal located near the phone identified.
  • the encrypted acoustic accreditations are on the contrary “downward” accreditations, that is to say that they come from a remote management site and transmitted to the mobile phone of the user.
  • the invention relates, in a manner known per se, to a secure system for controlling the opening of lock devices, of the general type disclosed by the WO 03/093997 A1 above, comprising the elements set forth in the preamble of claim 1.
  • the invention proposes to combine the elements stated in the characterizing part of claim 1.
  • One of the essential elements of the invention is a secure management site 10 centralizing in a database DB 12 information to identify and identify a number of locks and authorized users for each of these locks. For each user, the database lists a unique mobile phone number associated with this user, as well as access right data and conditions of use (access reserved for certain days or certain time slots, expiry date right of access, etc.).
  • the database also lists for each lock a Unique IDentifier (UID) that is uniquely assigned and uniquely identifies the lock in the various data exchange protocols.
  • UID Unique IDentifier
  • Other data may also be stored by the database, including the algorithms used by the lock, one or more cryptographic keys, a simplified free name ("entry”, “garage”, “cellar”, etc.) to facilitate the selection by a user of one of several locks, etc.
  • the management site 10 also comprises a cryptographic engine forming a generator 14 of accreditation data.
  • the "accreditation data" are encrypted acoustic accreditations or CAC (Crypto Acoustic Credential) in the form of single-use audio signals, for example (but not limited to) made of a succession of dual DTMF tones. These audio signals are designed so that they can be conveyed after digitization by telephone audio transmission channels and reproduced as such by acoustic transducers.
  • the site manager 10 is coupled to a network 16 of a mobile network operator MNO (Mobile Network Operator) via an audio telephone gateway PGW (Phone GateWay) 18 and a secure connection 20, e.g. IP link type https , so as to convey acoustic accreditations from the generator 14 to telephone 22 of the user through the audio transmission channels (voice channel) of the mobile network.
  • MNO Mobile Network Operator
  • PGW Packet GateWay
  • secure connection 20 e.g. IP link type https
  • the mobile telephone network 16 is used in a conventional manner by its various subscribers, each user being in possession of a mobile phone 22 of his own, individualized by the information of the SIM card contained in the telephone set or by another unique feature if the phone operates without a SIM card.
  • a user is recognized and identified by the network 16 by means of his subscriber number, and therefore in the same way by the management site 10.
  • Securing the link between the network 16 and the mobile phone 22 can be operated via a trusted service provider or TSM ( Trusted Service Manager ), able to ensure efficiently and safely the various procedures that the description will be exchange or transmission of information between the management site 10 and the mobile phone 22 via the mobile network operator 16.
  • TSM Trusted Service Manager
  • the object used is a mobile phone, so a trivialized object. But it is recognized and authenticated by the SIM card it contains (or by another single element) and which, above all, identifies the user via his phone number (subscriber number).
  • the management site 10 can thus identify a telephone to which it has been connected via the mobile network operator 16 as being that of the authorized user, listed in his database 12.
  • the implementation of the invention involves reproducing by the speaker 24 of the mobile telephone 22, as an audio signal, the encrypted acoustic accreditation generated by the cryptographic generator 14 and transmitted as a voice signal by the intermediary of the telephone gateway 18 and the operator of the mobile network 16.
  • Accreditation reproduced by the speaker 24 of the mobile phone is intended to be picked up by a microphone 26 of a lock 28 so as to control the opening of this lock. It's about allowing the user, holder of the mobile phone number 22 known from the database 12, to prove to the lock 28 that he has the identity that he proclaims, and that he has the rights of access allowing the opening of this lock.
  • the reproduced sound signal thus constitutes a proof of the user's identity and of his opening rights, hence the terminology "acoustic accreditation”.
  • This acoustic accreditation is also encrypted (by cryptographic means in themselves known), and it is disposable to avoid any fraud by recording and duplication, otherwise it would be very easy to record the acoustic signal and then reproduce it at will.
  • the Figure 2 illustrates in the form of block diagram the main organs of the mobile telephone 22 and the lock 28.
  • the telephone 22 comprises a microcontroller 30 coupled to various peripheral devices such as a transmission / reception circuit 32, a display 34, a keyboard 36, a data memory 38, a corresponding UICC card ( Universal In-tegrated circuit card). the "SIM card” for GSM telephony functions) 40, and the acoustic transducer 24.

  • Various precautions may be provided to increase the security of the process, in particular by an additional validation requested by the user, for example the input of a personal code of the "PIN code” type, or a validation of biometric type, by a biometric reader incorporated in the telephone or by means of a voice recognition system using the telephone microphone (the specific biometric fingerprint that can be stored in the memory 38 of the telephone, or in the UICC card 40, or in the database 12).

  • This accreditation in DDC digital data read by the module 52 in a key or badge that the user has coupled with this module, is analyzed by the microcontroller 44 which conditionally issues an authorization to open the lock 46 if the required criteria are met. completed, including the conformity of the UID.
  • the invention proposes to replace the module 52, or to complete this module 52, by a module 54 able to process accreditations sent to the lock in the form of acoustic accreditations CAC transmitted by a mobile phone 22, instead of DDC digital accreditations read from a card or badge coupled to module 52.
  • the acoustic module 54 is provided with an acoustic transducer in the form of a microphone 56 making it possible to pick up the surrounding sound signals, in particular the acoustic accreditation which will be reproduced by the loudspeaker 24 of the telephone 22, and to transform the signals acoustics captured in digital signals applied to a stage 58 forming a translator, for converting the acoustic accreditations CAC into signals of the same format as the accreditations in digital data DDC would have provided the module 52 by reading a badge or a card.
  • the acoustic module 54 also comprises, advantageously, a transducer 60 making it possible to reproduce a sound signal emitted by the stage 58 and audible from outside the lock, this transducer 60 possibly comprising a loudspeaker or, in a version simplified, a simple component type buzzer (buzzer). It is also possible to use the transducer 46 of the acoustic module 54 by operating it in inverted mode (to emit sound signals instead of sensing them).
  • the primary object of the invention is to replace, or supplement, the "proprietary" technology, specific to the manufacturer and implemented in the reader module 52, with a universal technology based on CAC encrypted acoustic accreditations, which can be implemented without substantial modification of the lock components, both hardware and software.
  • the basic principle is to retain original digital data (DDC) accreditations with their own manufacturer's content and format, and to convert these DDC accreditations into CAC Accreditations, to transmit CACs to the phone, then to have them reproduced by the manufacturer. the user, by means of the loudspeaker of his mobile phone, the acoustic accreditation CAC thus transmitted.
  • Accreditation captured by the acoustic module 54 is then subject to an inverse conversion, performed by the translation stage 58 incorporated in the acoustic module 54, in order to reconstitute the original DDC digital data accreditation from the Acoustic Accreditation CAC that has been captured.
  • a preliminary step is therefore to convert the DDC digital accreditation into a CAC encrypted acoustic accreditation.
  • DDC accreditations in the form of digital data blocks are converted by the cryptographic engine 14 of the secure site 10 into acoustic accreditations CAC.
  • the conversion can be carried out from a data block in which the fields VID, UID and DATA are presented explicitly, to a field CORE / CAC of the acoustic accreditation CAC (of the line a towards the line c of the Figure 3 ).
  • the cryptographic engine may well receive at this stage the information in a non-explicit form (CORE), which is directly converted to give the CORE / CAC field of acoustic accreditation CAC (from line b to line c of the Figure 3 ).

  • the cryptographic engine 14 also adds to the field CORE / CAC containing the actual accreditation data a variable field, different at each generation of an acoustic accreditation, so as to make this acoustic accreditation unique. It may be data generated by a pseudo-random generator or, preferably, a sequence number SEQ.
  • the field SEQ may be a counter incremented each generation of an accreditation by the cryptographic generator 14, or a time stamp that will be functionally equivalent to the incrementation of a counter.
  • the cryptographic generator 14 may also provide for the addition to the acoustic accreditation CAC of a password PWD making it possible to further increase the security of the process.
  • the user comes into contact with the management site by any appropriate means. This can be achieved by calling a phone number, or sending a message (SMS, MMS, e-mail, instant messaging, etc.) to the server, which will call back the user's phone for issue the authorization in the form of encrypted acoustic accreditation.

Regardless of how the user comes into contact with the remote site, the latter delivers the acoustic accreditation directly to the user, without intermediate storage.
