The present invention relates to a system (10) operable to control access to different physical spaces, each provided with an electrical locking device (121, . . . , 12n), with the aid of a programmable, mobile unit (14). The system (10) comprises an authority means (16) operable to issue access rights connected to the programmable, mobile unit (14) in the form of an authorizing data (AD), which authorizing data (AD) is sent to an authorization means (18) connected to the authority means (16), and operable to generate an alpha-numerical key for the mobile unit (14), and to send the alpha-numerical key and a unique identifier of the mobile unit (14) to an operator (20), which is connected to the authorization means (18). The operator (20) is operable to send the alpha-numerical key to the mobile unit (14) identified by the unique identifier. An electrical locking device (12i), wherein 1≦i≦n, and the mobile unit (14) uses an authentication protocol with the alpha-numerical key to authenticate the mobile unit (14), wherein the mobile unit, if it has been authenticated, sends the authorizing data (AD) to the electrical locking device (12i), and if the authorizing data (AD) comprises an identifier of the electrical locking device (12i), the mobile unit (14) is able to open the electrical locking device (12n) with the aid of a communication means (22) comprised in the mobile unit (14) for communication in the near field.
A system (10) operable to control access to different physical spaces, each provided with an electrical locking device (12i, . . . , 12n), with the aid of a programmable, mobile unit (14), characterized in that said system (10) comprises an authority means (16) operable to issue access rights connected to said programmable, mobile unit (14) in the form of an authorizing data (AD), which authorizing data (AD) is sent to an authorization means (18) connected to said authority means (16) and operable to generate an alphanumerical key for said programmable, mobile unit (14) and to send said alphanumerical key and a unique identifier of said mobile unit (14) to an operator (20), which is connected to said authorization means (18), wherein said operator (20) is operable to send said alphanumerical key to said mobile unit (14) identified by said unique identifier, wherein an electrical locking device (121), wherein 1≦i≦n, and said mobile unit (14) uses an authentication protocol with said alphanumerical key to authenticate said mobile unit (14), wherein said mobile unit (14), if it has been authenticated, sends said authorizing data (AD) to said electrical locking device (121), and if said authorizing data (AD) comprises an identifier of said electrical locking device (120 said mobile unit (14) is able to open said electrical locking device (121) with the aid of a communication means (22) comprised in said mobile unit (14) for communication in the near field.
A system (10) operable to control access to different physical spaces according to claim 18, characterized in that said mobile unit (14) also is operable, if said mobile unit (14) and said electrical locking device (12i) have been authenticated, to send said authorizing data (AD) and said authorization data electronically signed by said authorization means (18) private key (SignprivA (AD)) to said electrical locking device (12j), which verifies said signature.
A method for controlling access to different physical spaces, each provided with an electrical locking device (121;
