The ASIC combines sensor inputs necessary to monitor ambient light levels, light color, occupation/motion sensors, security sensors, temperature and humidity, barometric pressure, smoke and toxic substance sensors, and a processor to receive the sensor inputs and deliver control output signals to effect changes and make settings to each of the environmental systems that are monitored. The ASIC also provides communication and control security for the building management system, preventing hostile intrusions into the system. The storage, intelligence and processing all reside within the ASIC. ## Claims ### Claim 1 An operations management system comprising an integrated sensor network and control system, said control system comprising a local security area further comprising a self-contained communication and control security system, including storage devices, intelligence, and a processor, that maintain a ledger of all transactions stored in the local security area and that requires validation of said ledger before accepting data or commands from any device in the control system, and which a count of all transactions is a seed establishment of a security key. ### Claim 2 (depends on 1) The operations management system of claim 1, wherein the count of all transactions is combined with the ledger of all transactions to establish the security key. ### Claim 3 (depends on 2) The operations management system of claim 2, wherein each time a new security key is reseeded into system transactions replacing a prior key, the new security key is preceded with the prior key for validation. ### Claim 4 (depends on 1) The operations management system of claim 1, wherein the self-contained communication and control security system prevents hostile intrusion into both sensor and control transactions to and from the operations management system ensuring that control transactions are based on actual sensor data and that control transactions for managed operations are valid. ### Claim 5 (depends on 1) The operations management system of claim 1, wherein a current blockchain is communicated to a remote device in a network of devices in the operations management system, said remote device is commissioned by seeding said remote device with a current blockchain, a media access control (MAC) address of said remote device is recorded into an active device library maintained by the self-contained communication and control security system prior to the remote device's admission into the device network of the operations management system after the MAC address is validated. ### Claim 6 (depends on 1) The operations management system of claim 1, wherein a remote device in a network of devices in the operations management system is commissioned by seeding said remote device with a current cyclic redundancy check (CRC), a media access control(MAC) address of said remote device is recorded into active device library maintained by the self-contained communication and control security system prior to the remote device's admission into the device network of the operations management system after the MAC address is validated. ### Claim 7 (depends on 1) The operations management system of claim 1, wherein said operations management system is private cloud connected. ### Claim 8 A private cloud connected operations management system, said operations management system comprising networked sensors and controlled devices that maintain a ledger of all transactions within each controlled device and require validation of that ledger before accepting data or commands from any device, and in which a count of all transactions is used as a key in combination with the ledger of transactions. ### Claim 9 (depends on 8) The system of claim 8 wherein each time a new security key is reseeded into system transactions replacing a prior key, the new security key is preceded with the prior key for validation. ### Claim 10 An operations management system comprising an integrated sensor network and control system, said control system comprising a local security area further comprising a self-contained communication and control security system, including storage devices, intelligence, and a processor, that maintain a ledger of selected transactions stored in the local security area and that requires validation of said ledger before accepting data or commands from any device in the control system, and in which a count of said transactions is a seed for establishment of a security key. ### Claim 11 (depends on 10) The operations management system of claim 10, wherein the count of said selected transactions is combined with the ledger of transactions to establish the security key. ### Claim 12 (depends on 11) The operations management system of claim 11, wherein each time a new security key is reseeded into system transactions replacing a prior key, the new security key is preceded with the prior key for validation. ### Claim 13 (depends on 10) The operations management system of claim 10, wherein the self-contained communication and control security system prevents hostile intrusion into both sensor and control transactions to and from the operations management system ensuring that control transactions are based on actual sensor data and that control transactions for the managed operations are valid. ### Claim 14 (depends on 10) The operations management system of claim 10, wherein said operations management system is private cloud connected. ### Claim 15 (depends on 10) The operations management system of claim 10, wherein a current blockchain is communicated to a remote device in a network of devices in the operations management system, said remote device is commissioned by seeding said remote device with a current blockchain, a unique device identifier of said remote device is recorded into an active device library maintained by the self-contained communication and control security system prior to the remote device's admission into the device network of the operations management system after the unique device identifier is validated. ### Claim 16 (depends on 10) The operations management system of claim 10, wherein a remote device in a network of devices in the operations management system is commissioned by seeding said remote device with a current cyclic redundancy check (CRC), a unique device identifier of said remote device is recorded into an active device library maintained by the self-contained communication and control security system prior to the remote device's admission into the device network of the operations management system after the unique device identifier is validated.
