Abstract: ABSTRACT The present disclosure relates to tamper-evident environmental monitoring of temperature-sensitive goods. The apparatus (102) includes a sensor node (104) with a temperature sensor (106) that measures ambient temperature and outputs a temperature value. A cryptographic co-processor (108), coupled to the temperature sensor (106), incorporates a hardware hash engine, a digital signature engine, and tamper-resistant secure memory storing a private key. The cryptographic co-processor (108) computes a hash digest of temperature data packets, generates a digital signature using the stored private key, and transmits resulting signed data packets to a gateway controller (110). The gateway controller (110) includes a ledger interface circuit (112) that verifies digital signatures against a corresponding public key and commits verified signed data packets as transactions to a distributed cryptographic ledger (114) maintained across independently operated computing nodes. Any post-generation alteration of signed data packets remains detectable by any party holding corresponding public key. FIG. 1
