[0002] With the advent of the intelligent era, the role of chips is becoming more and more important, and the security of chips has also attracted more attention.

[0003] The current chip security faces frontiers threats such as side-channel attack and fault injection attack. Side-channel attack, also known as side-channel attack, is a passive attack based on observation. The main method is to attach a high-precision probe close to the surface of the chip to collect the tiny signals in the running of the chip, and then use a specific password algorithm to statistically analyze the collected signals, so as to crack the chip running password. Fault injection attack is divided into electromagnetic, laser, voltage glitch, clock glitch, etc. Among them, electromagnetic and clock glitch attack is to attach a specific electromagnetic or clock glitch generating device close to the surface of the chip to send interference signals, thereby disturbing the chip calculation and making the chip run wrong. Then use a specific password algorithm to count the error information, and finally realize the reverse calculation of the chip running password.

[0004] In the related art, when the chip is analyzed for security in the above manner, some devices are used to hold high-precision probes or fault generating devices to make the high-precision probes or fault generating devices close to the chip.

[0039] In some possible implementation manners, as shown in Figure 1 and Figure 2 The fixed driving assembly 1 can be arranged in a structure form comprising a base 11, a driving piece 12 and a moving piece 14, the swing piece 2 is movably arranged on the moving piece 14, the moving piece 14 is slidingly connected with the base 11, the driving piece 12 is fixed on the base 11 and is in transmission connection with the moving piece 14, and the driving piece 12 can drive the moving piece 14 to move relative to the base 11.

[0040] Exemplarily, the base 11 is provided in a structure form comprising a support 111 and a guide rail 112. For example, the support 111 is provided in a structure extending in the vertical direction, two guide rails 112 are provided on one side of the support 111, the two guide rails 112 are also provided in the vertical direction, and the two guide rails 112 are parallel to each other. The driving member 12 can be fixed at one end of the support 111, and the output shaft of the driving member 12 can pass through the end of the support 111, and the driving member 12 can be a servo motor, a stepper motor or a common motor, etc. A transmission member 13 is provided, and the transmission member 13 is in transmission connection with the output shaft of the driving member 12. A sliding groove matched with the two guide rails 112 can be provided on the moving member 14, and the moving member 14 is slidably arranged on the two guide rails 112 through the two sliding grooves. Meanwhile, a structure matched with the transmission member 13 is provided on the moving member 14, so as to transmissionally connect the moving member 14 with the transmission member 13. For example, the transmission member 13 is provided as a threaded rod, and a threaded hole matched with the threaded rod is provided on the moving member 14, so as to connect the transmission member 13 with the moving member 14 through the threaded connection. The transmission member 13 and the moving member 14 can also be provided in a structure form of a ball screw. In this way, when the driving member 12 drives the transmission member 13 to rotate, the transmission member 13 can drive the moving member 14 to move along the two guide rails 112, so as to drive the swing member 2 and the carrier 3 to move.

[0041] In other possible implementation manners, in order to facilitate the connection of the swing member 2 and the moving member 14, as shown in Figure 1 and Figure 2 , a housing 6 can be arranged between the swing member 2 and the moving member 14, the housing 6 is fixedly connected with the moving member 14, and the swing member 2 is movably arranged in the housing 6, so as to movably connect the swing member 2 with the fixed driving assembly 1.

[0042] Exemplarily, referring to Figure 3 and Figure 4 , Figure 3 and Figure 4 are partial structures of the device for chip 02 security analysis provided by the present application, as shown in Figure 3 and Figure 4 , the housing 6 can be provided as an open box-shaped cuboid, that is, the open box-shaped housing 6 has five surfaces. In the direction of the long axis of the housing 6, one end of the housing 6 is fixedly connected with the moving member 14, a connecting through hole is arranged at the other end of the housing 6, the swing member 2 is hingedly connected to the inner wall of the housing 6, and the carrier 3 passes through the connecting through hole and is connected with the swing member 2. In this way, the swing member 2 can move relative to the housing 6 through the hinged point with the housing 6. It should be noted that the housing 6 can also be provided in other forms, for example, a plate-shaped structure extending from the moving member 14 is used to arrange the swing member 2 and the carrier 3, so as to connect the swing member 2 with the fixed driving assembly 1 through the plate-shaped structure. The specific structure of the housing 6 is not limited in the embodiments of the present application.

[0043] Another example, as shown in Figure 3 and Figure 4 , the support 7 can be provided, one end of the support 7 is hinged to the inner wall of the shell 6, and the other end of the support 7 is hinged to the middle part of the swing piece 2 in the axial direction of the swing piece 2. In this way, the swing piece 2 is hinged to the inner wall of the shell 6 by the support 7, not only can make the swing piece 2 with the hinge position of the support 7 as the pivot, relative to the shell 6 rotation, but also in the axial direction of the swing piece 2, the swing piece 2 can drive the support 7, the support 7 with the hinge position of the inner wall of the shell 6 as the pivot, relative to the shell 6 movement.

[0044] In yet another possible implementation, a sliding piece 8 can be provided on the shell 6 away from one end of the moving piece 14, the sliding piece 8 is hinged to one end of the swing piece 2 through the connecting through hole on the shell 6, and the carrier 3 is fixedly connected with the sliding piece 8.

[0045] Exemplarily, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the sliding piece 8 can be provided in the form of a structure including a sliding part 81 and a fixed part 82, the fixed part 82 is extended from one side of the sliding part 81, or the fixed part 82 is manufactured separately from the sliding part 81, and then the two are fixedly connected. Among them, the carrier 3 is fixed on the sliding part 81 away from the fixed part 82, and a sliding structure is provided between the sliding part 81 and the shell 6, through which the sliding part 81 can be slidably arranged on the shell 6 at a position corresponding to the connecting through hole, and through the sliding structure, the sliding piece 8 can be moved in the direction of the safety analysis piece 01 moving towards or away from the chip 02; and the fixed part 82 passes through the connecting through hole and is hinged to the swing piece 2.

[0046] Another example, the sliding structure between the sliding part 81 and the shell 6 can be provided in the form of a structure including a sliding slot 811 and a second fastener 10. For example, at least one sliding slot 811 is provided on the sliding part 81 in the direction of the safety analysis piece 01 moving towards the chip 02, and a second fastener 10 is used to pass through the sliding slot 811, and the second fastener 10 is connected with the shell 6, so that the sliding piece 8 is slidably arranged on the shell 6 through the sliding slot 811 and the second fastener 10. For example, two parallel sliding slots 811 are provided on the sliding part 81, two bolts are provided in each sliding slot 811 as the second fastener 10, and the bolts are threadedly connected with the shell 6, so that the sliding piece 8 is slidably arranged on the shell 6 through the four bolts and the two sliding slots 811.

[0047] In another example, the sliding structure between the sliding part 81 and the housing 6 can also be provided in the form of a structure including a guide rail and a sliding block. For example, two parallel guide rails are provided on one end of the connecting through hole of the housing 6, and a sliding block adapted to the guide rail is provided on the sliding part 81 of the sliding member 8, or the sliding part 81 is provided in the form of a sliding block; or a guide rail is provided on the sliding part 81, and a sliding block adapted to the guide rail is provided on the housing 6. In this way, the sliding member 8 and the housing 6 can be connected through the guide rail and the sliding block.

[0048] In this embodiment, by providing the sliding member 8, the carrier 3 and the swinging member 2 can be movably connected through the sliding member 8; and by providing a sliding structure between the sliding member 8 and the housing 6, the movement direction of the sliding member 8 relative to the housing 6, i.e., relative to the fixed driving assembly 1, can be limited through the sliding structure, so that the movement path of the security analysis element 01 or the chip 02 fixed on the carrier 3 is fixed and stable. When the security analysis element 01 or the chip 02 is driven to move by the device for chip security analysis, the path of the security analysis element 01 and the chip 02 approaching each other is fixed, so that the security analysis element 01 and the chip 02 can abut at a set position. At the same time, the sliding member 8, the support 7, the housing 6 and the swinging member 2 form a four-bar mechanism. Since the sliding member 8 moves in a straight line, one end of the swinging member 2 is hinged to the sliding member 8, and the middle part of the swinging member 2 is hinged to the support 7. Therefore, during the movement of the swinging member 2 driven by the sliding member 8, the swinging member 2 not only produces movement in the same direction as the sliding member 8, but also produces rotation around the support 7 under the limitation of the support 7. Since the other end of the support 7 is also hinged to the housing 6, the support 7 does not limit the movement of the swinging member 2.

[0049] In some other possible implementations, in order to improve the sensitivity of the device for chip security analysis, a rolling member 9 can be provided between the sliding part 81 and the housing 6, so that the sliding part 81 is connected to the housing 6 through the rolling member 9.

[0050] For example, four universal balls can be provided between the sliding part 81 and the housing 6. A linear bearing can also be provided between the sliding part 81 and the housing 6 to connect the sliding part 81 and the housing 6 through the linear bearing. A plurality of rolling balls can also be provided between the sliding part 81 and the housing 6. In this way, the sliding connection between the sliding part 81 and the housing 6 can be changed to rolling connection through the universal ball, the linear bearing or the rolling ball, so that the friction between the sliding part 81 and the housing 6 during relative movement can be reduced, and the sensitivity of the carrier 3 driving the swinging member 2 when the security analysis element 01 and the chip 02 abut can be improved.

[0051] In some other possible implementations, asFigure 1 and Figure 2 In the above manner, the carrier 3 can be provided in a structure including a carrying portion 31 and a suspending portion 32. Exemplarily, the carrying portion 31 is provided with a structure for carrying and fixing the security analysis component 01 and / or the chip 02, and the suspending portion 32 is connected with the carrying portion 31 to fix the carrier 3 on the sliding portion 81 of the slider 8 through the suspending portion 32. For example, the carrying portion 31 can be provided in a structure capable of clamping a high-precision probe; the carrying portion 31 can also be provided in a structure capable of fixing a fault injection device; the carrying portion 31 can also be provided in a structure capable of fixing the chip 02; or the carrying portion 31 can be provided in other required structures as long as the structures are capable of carrying and fixing components required for security analysis of the chip 02.

[0052] Meanwhile, the carrying portion 31 and the suspending portion 32 of the above at least three different structures can be connected in a detachable manner. In this way, different carrying portions 31 can be replaced conveniently, so that the device for chip security analysis can carry and drive one of the security analysis component 01 and the chip 02 to move towards the other of the security analysis component 01 and the chip 02, thereby making the device for chip security analysis applicable to various application scenarios.

[0053] In yet some possible implementation manners, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 The output component 4 can adopt a micro switch. The micro switch is fixed on the inner wall of the housing 6 to be arranged on the fixed driving assembly 1 through the housing 6, and is located opposite to the end of the swinging component 2 away from the carrier 3, that is, the micro switch is located on the movement path of the swinging component 2. In this way, in the process that the swinging component 2 is driven by the carrier 3 to make the end of the swinging component 2 close to the micro switch move in an arc, the swinging component 2 can press against the micro switch, so that the micro switch generates a control signal. Through the control signal, the driving component 12 can be controlled to stop working, so that the carrier 3 stops moving.

[0054] The output component 4 can also adopt an infrared sensor. The infrared sensor is arranged in the housing 6, and the light path of the optical system of the infrared sensor is located on the movement path of the swinging component 2. In this way, in the process that the swinging component 2 is driven by the carrier 3 to move in an arc, the swinging component 2 can reflect the light emitted by the optical system of the infrared sensor, so that the infrared sensor generates a control signal. It should be noted that the output component 4 can be any component capable of generating a control signal for stopping the driving component 12 from working in the process that the swinging component 2 moves, and the type of the output component 4 is not limited in the embodiments of the present application.

[0055] In some possible implementation manners, since the device for chip security analysis can carry different security analysis pieces 01 and different chips 02, in order to facilitate adjustment of the size of the triggering protection force of the device for chip security analysis, that is, adjustment of the size of the force when the different security analysis pieces 01 and the different chips 02 abut against each other, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , an adjusting assembly 5 can be arranged on the swing piece 2 away from the carrying piece 3, so as to adjust the torque on the end of the swing piece 2 away from the carrying piece 3 through the adjusting assembly 5, and then control the size of the abutting force between the security analysis piece 01 and the chip 02 through the size of the torque.

[0056] For example, referring to Figure 6 , Figure 6 , the partial structural schematic diagram of the device for chip security analysis provided by the present application is shown in Figure 4 and Figure 6 , the adjusting assembly 5 can be arranged in a structure form including a counterweight piece 51 and a first fastener 52, and the counterweight piece 51 is detachably arranged on the end of the swing piece 2 away from the carrying piece 3 through the first fastener 52, so that the position of the counterweight piece 51 on the swing piece 2 can be adjusted in the axial direction of the swing piece 2.

[0057] For example, the counterweight piece 51 is arranged in a structure form of two counterweight blocks, and a sliding groove is arranged between the abutting surfaces of the two counterweight blocks, which is matched with the swing piece 2, so as to slide the two counterweight blocks on the swing piece 2 through the sliding groove. Meanwhile, an adjusting through groove 21 extending in the axial direction of the swing piece 2 is arranged on the swing piece 2, and a first fastener 52 matched with the adjusting through groove 21 is arranged on the two counterweight blocks, and the first fastener 52 can be a hexagonal bolt, and a threaded hole matched with the hexagonal bolt is arranged on the counterweight block. An adjusting hole 61 corresponding to the sliding groove can also be arranged on the housing 6, and the adjusting hole 61 is arranged as an elongated hole. In this way, the hexagonal bolt passes through the adjusting through groove 21 to fix the two counterweight blocks on the swing piece 2, and the hexagonal bolt can be adjusted through the adjusting hole 61, so that the two counterweight blocks can slide relative to the swing piece 2, so as to adjust the position of the counterweight blocks on the swing piece 2, thereby adjusting the size of the torque on the end of the swing piece 2 away from the carrying piece 3.

[0058] For example, referring to Figure 5 , Figure 5 , the partial structural schematic diagram of the device for chip security analysis provided by the present application is shown in Figure 5As shown, the adjusting assembly 5 can also be configured in a structure form including an elastic member 54 and an adjusting member 53, the adjusting member 53 is threadedly connected on the housing 6, one end of the elastic member 54 is connected with the adjusting member 53, and the other end is connected with the end of the swing member 2 away from the bearing member 3, by adjusting the position of the adjusting member 53 on the housing 6, the deformation amount of the elastic member 54 can be adjusted, so as to change the size of the torque acting on the swing member 2.

[0059] For example, the adjusting member 53 can be a bolt, a threaded hole matched with the bolt is arranged on the shell wall of the housing 6, and the bolt is threadedly connected on the housing 6; the elastic member 54 can be a compression spring, the compression spring is arranged between the end of the swing member 2 away from the bearing member 3 and the bolt, that is, the compression spring is arranged at a position that can make the end of the swing member 2 away from the bearing member 3 move in the direction of the safety analysis member 01 moving close to the chip 02. Alternatively, the elastic member 54 can also be a tensile spring, one end of the tensile spring is connected with the bolt, and the other end is connected with the end of the swing member 2 away from the bearing member 3, and the tensile spring is arranged at a position that can make the end of the swing member 2 away from the bearing member 3 move in the direction of the safety analysis member 01 moving close to the chip 02. In this way, by screwing the bolt, the deformation amount of the compression spring or the tensile spring can be changed, so as to change the size of the torque acting on the end of the swing member 2 away from the bearing member 3.

[0060] In this embodiment, by arranging the adjusting assembly 5 on the end of the swing member 2 away from the bearing member 3, the size of the torque acting on the end of the swing member 2 away from the bearing member 3 can be adjusted by the adjusting assembly 5, and the weight of the different devices fixedly carried on the bearing member 3 can be matched by the torque, so as to adjust the size of the abutting force between the safety analysis member 01 and the chip 02, so that the size of the abutting force can meet the required contact force between the safety analysis member 01 and the chip 02, and the collision between the safety analysis member 01 and the chip 02 will not occur, and the bearing member 3 can move away from the chip 02 by the abutting force, so as to drive the slide member 8 and the swing member 2 to move, when the swing member 2 moves, the output member 4 can be triggered to generate a control signal, and then the size of the trigger protection force of the device for chip safety analysis on the safety analysis member 01 and the chip 02 can be controlled to adapt to different application scenarios of the safety analysis member 01 and the chip 02.

[0061] Referring to Figure 7 and Figure 8 , Figure 7 and Figure 8 are schematic diagrams of the device for chip safety analysis provided by the present application. As Figure 7As shown, when the chip 02 is subjected to safety analysis by the device for chip safety analysis, the position of the adjusting assembly 5 is first adjusted by using the adjusting tool 03 to adjust the size of the torque acting on the end of the swing member 2 away from the carrier 3, so that the size of the abutting force between the safety analysis member 01 and the chip 02 meets the requirement. Then, as shown, Figure 8 As shown, the driving member 12 is controlled to work to drive the safety analysis member 01 to move towards the chip 02 until the safety analysis member 01 abuts against the chip 02. When the size of the abutting force between the safety analysis member 01 and the chip 02 is consistent with the set size of the trigger protection force, the safety analysis member 01 drives the carrier 3 to move, the carrier 3 drives the sliding member 8 to move, and the sliding member 8 drives the swing member 2 to move, so that the end of the swing member 2 away from the carrier 3 performs circular motion, thereby triggering the output member 4 to generate a control signal. After receiving the control signal, the driving member 12 stops working. In this way, the abutting force between the safety analysis member 01 and the chip 02 will not increase any more, and collision between the safety analysis member 01 and the chip 02 can be avoided.

Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
