Embodiments of systems and methods are disclosed to detect tampering and/or provide cryptographic evidence of tampering. Tampering is detected and tamper evidence is provided by incorporating at least one tamper-evident assembly and at least one processing device within an enclosure housing a host device. The tamper-evident assembly includes one or more tamper-evident fasteners, each having an identification chip, which stores a unique identifier corresponding to the tamper-evident fastener and transmits the unique identifier through the tamper-evident fastener to the at least one processing device when the tamper-evident fastener is coupled to a surface of the enclosure to secure a point of entry on the enclosure. The processing device may detect tampering and/or provide cryptographic evidence of tampering when a hash of the unique identifier(s) detected when the host device is in use does not match a hash of the unique identifier(s) detected before the host device is used.

Systems, tamper-evident assemblies and methods to detect tampering and/or provide cryptographic evidence of tampering

Embodiments of systems are disclosed herein to detect tampering and/or provide evidence of tampering without human interaction or oversight. In the disclosed embodiments, tampering is detected and tamper evidence is provided by incorporating at least one tamper-evident assembly and at least one processing device within an enclosure. The tamper-evident assembly includes a tamper-evident fastener having an integrated circuit (IC) chip, which is embedded within the tamper-evident fastener and configured to transmit a data signal through the tamper-evident fastener to the at least one processing device when the tamper-evident fastener is coupled to a surface of the enclosure to secure a point of entry on the enclosure. In some embodiments, the at least one processing device is configured to detect tampering and/or provide evidence of tampering when the data signal transmitted from the IC chip is not received.
