Abstract: Device of the chip or electronic system-in-package type, comprising at least one element for protecting at least part of at least one face of the device, said protective element comprising at least: an attack detection element of the device comprising at least one GMI-effect electrically conductive material, and a magnetic field emitter to which said GMI-effect electrically conductive material is to be subjected, and wherein the GMI effect is to be achieved in said GMI-effect electrically conductive material when an exciting alternating electric current flows therethrough and when subjected to the magnetic field of the magnetic field emitter.

Abstract: A method is described for implementing a current service, of a chain of n services, the method including receiving, from the service preceding the current service in the chain, a first routing token comprising message routing data between the services of the chain and a first chaining token comprising data of evidence of a passage through the previous service, and verifying that the current service is a legitimate recipient of the first routing token. The method also includes implementing a function of the current service, generating a second chaining token based on the first chaining token and a second routing token determined from the first routing token, and transmitting, to the service following the current service in the chain, the second chaining token and the second routing token.

After implementing a function of the current service, the method also includes generating a current chaining token from a data of evidence of a passage through the current service, and transmitting, to the service following the current service in the chain, the current chaining token and a second routing token determined from the first routing token.

Abstract: The electrode comprises: a support defining a first lateral edge and an upper edge extending from the first lateral edge; a layer containing an active substance covering the support; and an electrical-connection tab devoid of the layer containing the active substance, the tab projecting from the upper edge in the vicinity of the first lateral edge; The electrode defines, in the vicinity of a second lateral edge of the support, a cutout extending, set back from the upper edge, in the continuation of the upper edge, towards the second lateral edge.

Abstract: The present invention relates to a workpiece holding device (101, 201) comprising a substantially spherical ball (107, 207) with means for releasably retaining a workpiece (901), a socket (102, 202) with a first ball-receiving surface (105, 205) and means for mounting said socket (102, 202) on a worktable (905), and means for releasably clamping said ball (107, 207) against said first ball-receiving surface (105, 205). The first ball-receiving surface (105, 205) is shaped on a ball-receiving element (104, 204) mounted moveable, within said socket (102, 202), along at least one axis in a plane substantially perpendicular to its clamping force. The invention also relates to a workpiece holding system comprising three workpiece holding devices (101, 201, 301), as well as to a method for using this workpiece holding system.
