Abstract: A computer-implemented system and methods for provisioning a security token are provided. An example method may include steps of: receiving, at a secure appliance and from a remote server, a command to encode a set of access information into the physical security token; generating, at the secure appliance, encrypted access information, comprising: providing the set of access information to a secure cryptoprocessor; and instructing the secure cryptoprocessor to use a cryptographic key stored in the secure cryptoprocessor to encrypt the set of access information; obtaining, from a security token reader, an indication of a presence of the physical security token being inserted into or presented to the security token reader; and provisioning the physical security token by transmitting, via a secured channel, the encrypted access information from the secure appliance to the security token reader for encoding the physical security token with the encrypted access information.

Abstract: A turbine engine includes a combustion chamber, comprising two coaxial axisymmetric walls extending one inside the other and delimiting between one another an annular air-circulation, an exterior wall, and at least one injector passing through the walls via ports, wherein the injector comprises a peripheral tube connected to the walls by three connections, at least two connections being of the slideway and/or ball-joint or bellows type.

Abstract: A turbo engine comprising an annular heat exchanger formed by an independent tube assembly assembled by holding means, and having a cylindrical cavity opening on the one hand in the outlet of the turbine, the tube assembly being housed in said cavity. The heat exchanger consists of a first annular bundle and at least one second annular bundle, coaxial with said first annular bundle. An annular closing structure determining an outer annular cavity into which gases from said first tube bundle exit to be deflected on a bottom towards an inner annular cavity, coaxial with the outer annular cavity, opening into the tubes of said second tube bundle.
