[0007] While the invention is amenable to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and will be described in detail. It is to be understood, however, that there is no intention to limit the invention to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the scope of the invention. DETAILED DESCRIPTION OF THE INVENTION

[0008] Aspects of the present disclosure relate to secure enclosures, and more particularly to secure enclosures that require ventilation.

[0009] Secure enclosures are used to protect the contents within the enclosure. Some secure enclosures require a mechanism to relieve pressure that can build up within the secure enclosure, which can result in false tamper detection unless effectively relieved. Constraints can make it difficult to ventilate the secure enclosure while maintaining the enclosure's tamper-detecting and / or tamper-resistant capabilities.

[0010] The present disclosure includes a tamper detection circuit embedded in an organic material that ablates a portion of the organic material to create a path from one side of the material to the other side of the enclosure, simultaneously allowing ventilation while maintaining the tamper detection circuit. A tamper detection system according to the present disclosure can include an organic material and a tamper detection circuit embedded in the organic material. A portion of the organic material is ablated to form a cut in the organic material. A portion of the tamper detection circuit separates a segment of the ablation path. Block The tamper detection circuitry remains intact, and the notch allows for the flow of gaseous substances between the first side of the organic material and the second side of the organic material.

[0011] The present disclosure includes a method for manufacturing a tamper detection system. The method can include obtaining a tamper detection circuit embedded in an organic material and ablating a portion of the organic material to form a notch. Ablating the notch can remove the organic material in the ablation path. A portion of the tamper detection circuit can extend beyond the ablation path. Block The tamper detection circuitry remains intact and the notch allows gas flow between the first side of the organic material and the second side of the organic material.

[0012] 1 illustrates a secure ventilation system 100, according to some embodiments of the present disclosure. A top view 100a and a side view 100b of the secure ventilation system 100 are provided.

[0013] The secure ventilation system 100 includes an organic substrate 112, an inorganic tamper detection circuit 114, and an opening 116. The organic substrate 112 may be any organic material, with the tamper detection circuit 114 suspended therein. The tamper detection circuit 114 may be any metal capable of conducting an electrical impulse capable of identifying tampering. The organic substrate 112 may include, for example, a polyimide substrate. The tamper detection circuit may include, for example, copper.

[0014] The opening 116 allows for ventilation of the system to allow fluid flow between the first and second sides of the system 100. The opening 116 is formed through the organic substrate 112, leaving the tamper detection circuitry 114 intact. The opening 116 can be formed by any means that allows for ablation of the organic material without compromising the electrical integrity of the tamper detection circuitry, so that an incision can be made to fluidly connect one side of the system 100 to the other side of the system 100.

[0015] Methods that can be used to form the openings 116 can include, for example, laser ablation or chemical ablation, or both. Laser ablation can be used by tuning a laser to ablate the particular organic material used in the organic substrate 112 while not interfering with the tamper detection circuitry 114. Chemical ablation can similarly be used by applying a chemical suitable for ablating the organic material to the substrate to form the desired openings 116.

[0016] In some embodiments, laser ablation may be preferred because it is easier to control the precise result with a laser. For example, in some embodiments, an angled opening (rather than directly perpendicular) may be preferred, and a laser may allow for precise angle adjustment. Additionally, using a laser may allow for a shadowing effect such that the substrate behind portions of the tamper detection circuit 114 is protected from ablation, which in some cases may help prevent shorting of the tamper detection circuit 114.

[0017] 2 illustrates a material 200 having a secure ventilation mechanism, according to some embodiments of the present disclosure. The material 200 is shown in a first environment 202, a second environment 204, and a third environment 206. In each environment, a side schematic view 222a, 224a, 226a is shown, as well as a top view 222b, 224b, 226b.

[0018] In first environment 202, light source 212 is directed onto the top of material 200, as shown in side view 222a. Top view 222b illustrates the visibility of the proposed incision locations in the material under the conditions of first environment 202. With light source 212 directed onto material 200, the incisions are not noticeable and may even be invisible to the naked eye. This ability for the incisions to be generally invisible enhances safety, as weaknesses in the material are not revealed by the ventilation mechanism. Additionally, in some embodiments, the only way to direct light onto material 200 is with an overhead-directed light source 212, so the ventilation system is generally invisible to an observer.

[0019] In the second environment 204, a light source 214 is applied underneath the material 200, as shown in side view 224a. Top view 224b shows the visibility of the proposed cut locations in the material under the conditions of the second environment 204. With the light source 214 applied underneath the material, the cuts are not noticeable because they appear like the other spaces between the copper traces; that is, they are visually indistinguishable from the part of the material 200 that holds the organic substrate. Thus, again, the cuts are not weakened.

[0020] In the third environment 206, light sources 216a and 216b are applied both above and below the material 200, as shown in side view 226a. Top view 226b illustrates the visibility of the proposed cut locations within the material under the conditions of the third environment 206. With light sources 216a and 216b applied both above and below the material, as with light source 214 applied only below the material, the cuts are inconspicuous because they appear similar to the other spaces between the copper traces. That is, they are visually indistinguishable from the portion of material 200 that holds the organic substrate. Thus, again, the cuts are not particularly vulnerable and are protected from an observer identifying a potential weakness in the system.

[0021] In some embodiments, the incisions can be formed by exposing the tamper detection circuit embedded in the organic material to an organic removal mechanism. The organic removal mechanism removes the organic material but not the inorganic material. In some embodiments, the organic removal mechanism can be a laser tuned to ablate the organic material while sparing the tamper detection circuit, such that the organic material in the laser's drill path is removed and the tamper detection circuit in the laser's drill path remains intact.

[0022] 3 illustrates a material 300 undergoing a secure ventilation process, according to some embodiments of the present disclosure. More specifically, material 300 is shown in a first state 302. In first state 302, material 300 has been identified for use in implementing a secure ventilation system, and ablation locations for ventilation have been identified. A second state 304 illustrates material 300 after a cut has been made by ablating organic material within the drill path of a laser used to ablate the cut in material 300.

[0023] In many applications, it is desirable to use laser ablation of organic materials because the shape of the drill path, and therefore the shape of the cut, can be precisely determined. The laser must be properly tuned not only to the application, but also to the specific components within the material used for ventilation (e.g., substrate and tamper detection circuitry). Tuning the laser to the specific components within the material allows the laser to ablate the organic material while leaving the tamper detection unit intact. Specifically, maintaining the electrical integrity of the substrate ensures that the material maintains its detection capabilities.

[0024] In some embodiments, a multilayer polyimide substrate with copper traces can be used as the secure vent material. The copper traces form a tamper detection circuit and are therefore sometimes referred to as a secure mesh. In some embodiments, a laser can be used to remove (or laser ablate) the organic material. A variety of laser wavelengths, from ultraviolet to infrared wavelengths, can be used to laser ablate the organic material while leaving the security trace intact. Similarly, a variety of laser pulse widths, from continuous wave (CW) to femtosecond pulses, can be used to laser ablate the organic material while leaving the security trace intact.

[0025] In some embodiments, a radio frequency (RF) laser can be used to ablate organic materials (such as polyimide substrates) while leaving tamper detection circuitry (such as copper traces) intact. The RF laser can be tuned to a wavelength of 1035 nm, a pulse width of 300 fsec, an amplifier of 1 MHz, a splitting mode of 5, a pulse repetition rate (PRR) of 200 KHz, and an RF of 30. Those skilled in the art will recognize other specifications for tuning the laser depending on the materials used in other embodiments.

[0026] Similarly, the scanner can be configured to specific specifications to optimize the laser's ability to ablate material. In the embodiment described above using a polyimide substrate, copper traces, and an RF laser, the scanner can be configured for a scan speed of 1 M / s, a line spacing of 0.05 mm, and a FWHM of 10-15 μm. Those skilled in the art will recognize desirable scanner specifications for other embodiments.

[0027] 4 shows a material 400 with secure ventilation, according to an embodiment of the present disclosure. The material 400 is ablated by a laser on a first side 402a such that a cut traverses the entirety of the material. The cut is therefore visible on a second side 402b of the material 400. The force of the laser ablating the first side 402a of the material can leave an ablation bevel between the cut and the surrounding portion of the material 400.

[0028] The width of the drill path of the laser used to ablate the material, and therefore the width of the incision formed by the laser in the material, can vary. The width of the incision can be affected by other factors related to the ventilation system, specifically the length of processing time required, the amount of fluid flow through the incision, and how the material is ablated, among other factors. In one embodiment, ventilation incisions can be formed by drilling 100 μm diameter through-holes with a processing time of less than 4 seconds using a laser. In another embodiment, a large ventilation incision (e.g., as shown in FIG. 5 ) has an ablation area with a large width and can be ablated with a laser from both the first and second sides to ablate the organic material in the ablation area and expose the through-hole between the tamper detection elements. In such an embodiment, more processing time may be required.

[0029] FIG. 5 illustrates a material 500 with secure ventilation, according to some embodiments of the present disclosure. The material 500 has large ventilation cutouts. The material 500 is shown from a first side 502a and a second side 502b. The cuts begin on the first side 502a, initiating a vent and penetrating halfway through the material 500. The cuts then extend from the second side 502b through the remainder of the material 500, completing the vent. The illustrated material 500 uses a polyimide substrate as the organic material and copper traces as the tamper detection circuitry. The copper traces can be seen crossing each other with ablation. Through-holes can be seen between the copper traces. These through-holes allow ventilation while maintaining the electrical integrity of the detection circuitry.

[0030] In some embodiments, the large ventilation cutout can have an ablation region with a width of 1.5 mm, where the laser ablates from both a first side (e.g., the side adjacent to the protected resource) and a second side (e.g., the side facing the exterior) to ablate organic material (e.g., a substrate such as a polyimide substrate) within the ablation region to expose through-holes between tamper detection elements (e.g., copper traces). In such embodiments, the laser is tuned to remove the substrate without adversely affecting the tamper detection circuitry, so that spaces between the tamper detection circuits can be ablated to allow ventilation while leaving the electrical integrity of the tamper detection circuitry intact.

[0031] In some embodiments, maintaining organic material between tamper sensor traces can prevent shorting of the tamper detection system. Laser ablation of material according to embodiments of the present disclosure can leave a shadow behind the area of ​​the tamper detection circuit. For example, if a laser ablates a polyimide substrate but not a copper trace, the copper trace overlying the polyimide substrate protects the overlying polyimide substrate from ablation. That is, a laser tuned to ablate organic material will not ablate organic material behind inorganic material. Therefore, with this technique, the organic material between the tamper sensor traces is protected.

[0032] 6 shows a schematic diagram of a material 600 with secure ventilation, according to some embodiments of the present disclosure. The schematic diagram of material 600 shows a first segment of secure ventilation material 610 and a second segment of secure ventilation material 620. First segment 610 includes organic material 612 (e.g., a polyimide substrate) and traces 614 (e.g., copper) of a tamper detection system.

[0033] The first segment 610 includes a first cut 616a and a second cut 616b. The cuts may be vertical, angled, cornered, or some combination thereof. The cuts must connect a first side (e.g., the side facing the protected resource) to a second side (e.g., the side facing the exterior) to allow ventilation (e.g., gas flow from one side to the other). In the first segment 610, the first cut 616a is a straight vertical cut. The second cut 616b is an angled cut. In some embodiments, angled cuts, such as the second cut 616b, may be preferred to increase the difficulty of successfully gaining unauthorized access to the protected resource.

[0034] In some embodiments, the cut can be formed by ablating the material multiple times. A first ablation can be laser drilled on a first side of the organic material, and a second ablation can be laser drilled on a second side of the organic material. In some embodiments, the angle of the cut formed by the first ablation and the second ablation is between 60° and 120°. The angle of the cut can be where the two ablations meet or intersect.

[0035] A second segment 620 of the secure ventilation material has an organic material 622 (e.g., a polyimide substrate) and traces 624 (e.g., copper) of the tamper detection system. The second segment 620 includes a first notch 626a, a second notch 626b, and a third notch 626c. The first notch 626a is a vertical notch, the second notch 626b is an angled notch, and the third notch 626c is an angular notch.

[0036] In FIG. 6, the vectors (straight portions of the cut) of the third cut 626c intersect at approximately a right angle (a 90° angle). Other meeting angles according to the present disclosure may be used so long as ventilation is promoted between the first side of the material and the second side of the material. For example, in some embodiments, a 35° meeting angle may be preferred, while in other embodiments, a 155° meeting angle may be preferred. In some embodiments of the present disclosure, an exact 90° angle may be preferred, and in some embodiments of the present disclosure, a meeting angle in the range of 60° to 120° may be preferred.

[0037] In some embodiments, multiple angled cuts can be employed. In such embodiments, the same meeting angle can be used throughout the ventilated material. For example, all cut vectors can intersect at an angle of approximately 85°. In such embodiments, the meeting angles of the cuts can be varied. For example, a material with three ventilation cuts can have meeting angles of 102°, 93°, and 24°. In some embodiments, a combination of unique and replicated meeting angles can be used. For example, a material with four ventilation cuts can have meeting angles of 102°, 93°, 24°, and 93°.

[0038] Ventilation notches can be used one or more times on a material. In some embodiments, the ventilation material can be a relatively small component of the secure system. For example, the ventilation material can be embedded in the mechanical can such that there are openings through the mechanical can on either side of the notch opening. In such embodiments, fewer notches (e.g., only one) may be preferred to minimize the required opening of the mechanical can. In some embodiments, the ventilation material may be applied on top of the mechanical can rather than inside the mechanical can. In such embodiments, fewer notches (e.g., three) may be preferred to minimize the size of the opening in the mechanical can while maximizing the ventilation capacity of the opening.

[0039] In some embodiments, the ventilating material can form the entire secure enclosure. For example, the ventilating material may form a sphere surrounding a polygonal sphere that levitates the protected resource using magnets affixed inside the triangular joints of the polygon. In such embodiments, multiple notches (e.g., one on the center of the various lines of the polygon) can be used to ventilate the protected resource.

[0040] In some embodiments, the organic material and the tamper detection circuit embedded in the organic material can completely enclose the protected volume. Some embodiments of the tamper detection system can further include a mechanical can. The mechanical can can include a mechanical opening. The tamper detection circuit embedded in the organic material may be affixed over the mechanical opening of the mechanical can. In some embodiments, a tamper detection method according to the present disclosure can include affixing the tamper detection circuit embedded in the organic material to the mechanical can. The mechanical can can include a mechanical opening, and the tamper detection circuit embedded in the organic material may be affixed over the mechanical opening of the mechanical can.

[0041] 7 illustrates a system 700 utilizing materials with secure ventilation, according to some embodiments of the present disclosure. A first perspective shows a cross-sectional view 700a of the system 700, and a second perspective shows a top view 700b of the system 700.

[0042] System 700 includes a mechanical can 702 that connects to a circuit board 704 surrounding a protected resource 706. Mechanical can 702 has a mechanical opening 712. Mechanical opening 712 may be, for example, a hole that extends through mechanical can 702. Ventilated material 714 is attached to mechanical can 702 on the side of protected resource 706. System 700 further includes a tamper sensor 716 that extends around the entire inside perimeter of mechanical can 702.

[0043] In this embodiment, the ventilating material 714 is on the protected resource 706 side of the tamper sensor 716. In other embodiments, the ventilating material 714 may be between the tamper sensor 716 and the mechanical can 702, or may be integrated with the tamper sensor 716 as a combined unit. For example, the tamper sensor 716 may be embedded in the organic matter of the ventilating material 714, and in such embodiments, the organic matter of the ventilating material may partially or entirely cover the tamper sensor 716.

[0044] System 700 is also shown in a top view 700b. Top view 700b shows mechanical can 702, circuit board 704, and tamper sensor 716 through mechanical opening 712 in mechanical can 702. Top view 700b shows a second mechanical opening 722 in mechanical can 702. In this embodiment, tamper sensor 716 extends around the entire protected resource, such that tamper sensor 716 is visible through both mechanical opening 712 and second mechanical opening 722.

[0045] In some embodiments, the tamper detection system can further include a wire trap affixed to a first side of the organic material adjacent to the notch. The wire trap can include a tamper detection sensor and a bond member. The tamper detection sensor can be attached to the organic material via the bond member. The bond member can physically separate the tamper detection sensor from the organic material.

[0046] 8 shows a schematic diagram of a material 800 with secure ventilation, according to some embodiments of the present disclosure. The schematic diagram of material 800 shows a sliced ​​side view 820a and a top view 820b of a wire trap ventilation material 810, a wire trap 820. Wire trap ventilation material 810 includes an organic material 812 and a tamper detection trace 814. Wire trap ventilation material 810 includes angled ventilation cuts 816. Wire trap ventilation material 810 further includes a wire trap 820.

[0047] Wire trap 820 is shown in sliced ​​side view 820a and top view 820b. Wire trap 820 has a tamper sensor 824. Tamper sensor 824 can include a solid metal plate or woven copper fabric as part of the tamper detection circuit. In some embodiments, tamper sensor 824 can include a solid segment of non-breathable material (e.g., copper plate) because ventilation can occur around bond member 828. Bond member 828 can physically separate wire trap 820 from the rest of ventilated material 810 so that fluid (e.g., air) can flow between wire trap 820 and the rest of ventilated material 810.

[0048] In this embodiment, the tamper sensor 824 is on an organic base 822 (e.g., a polyimide substrate). In some embodiments, the tamper sensor 824 may exist independently of the organic base 822.

[0049] Top view 820b of wire trap 820 shows that bond member 828 is L-shaped over tamper sensor 824. Bond member 828 may be any shape that allows for fluid flow between wire trap 820 and the remainder of ventilated material 810. For example, in some embodiments, bond member 828 may include one or more posts of bond segments that connect tamper sensor 824 to the remainder of ventilated material 810.

[0050] 9 illustrates a system 900 utilizing a material with secure ventilation, according to some embodiments of the present disclosure. The system 900 includes a mechanical can 902 that connects to a circuit board 904 surrounding a protected resource 906. The mechanical can 902 has a mechanical opening 912. The system 900 further includes a tamper sensor 916 that extends around the entire inside perimeter of the mechanical can 902. A ventilated material 914 is attached to the mechanical can 902 on the side where the protected resource 906 is located. A wire trap 918 is attached to the ventilated material 914 between the ventilated material 914 and the protected resource 906.
