Methods to add an “Admission Control / Access Control” system to control access to a “Software-Defined-Deterministic Industrial Internet of Things” (SDD-IIoT) network are described. The SDD-IIoT comprises a “Software Defined Networking” (SDN) control-plane, and many “Software-Defined-Deterministic Wide Area Networks” (SDD-WANs). The SDN control-plane comprises 3 layers of “Zero Trust Architectures”, i.e., rule-based “Attribute-Based Access Control” (ABAC) systems, where subjects can request access to resources. A controller's “Knowledge-Base” consists of a set of facts and rules, which an inference-engine processes to make access decisions. Each SDD-WAN comprises a low-complexity deterministic forwarding-plane, with many simple deterministic packet switches (D-switches), realized with “Field Programmable Gate Arrays” (FPGAs). The forwarding-plane implements “Authenticated Encrypted Deterministic Channels” (AEDCs or D-flows) directly in hardware in layer-3, using Quantum Safe ciphers. Each D-flow has a deterministic data-rate requirement, with delay and jitter requirements. The D-switches can forward encrypted data, according to pre-defined periodic (repeating) deterministic schedules. For a packet to be accepted at the destination, it must be successfully decrypted at the destination in layer-3, using a Quantum Safe cipher. Malicious packets from cyber-attackers will fail the decryption process in layer-3, and thus be detected and removed. Each enterprise has an “Enterprise-Controller”, to control access to its private resources (i.e., computers, data-bases, etc), with an extensive knowledge base of rules. Each SDD-WAN has a “WAN-Controller”, to control the communications between enterprises over the SDD-WAN. If an Enterprise-Controller or WAN-Controller approves a request to establish a new D-flow, the SDN control-plane will download deterministic schedules and secret keys to the D-switches in the forwarding-plane. An IIoT-Controller will control the communications between different SDD-WANs. In an IIoT deployment, there may be 10s of WAN-Controllers, each with 100s of Enterprise-Controllers. These collaborative controllers work together, to control access to the bandwidth of the SDD-IIoT. They can achieve exceptionally-strong cyber-security, where the expected number of successful cyber-attacks per year from external cyber-attackers with Quantum Computers, can be reduced to zero. The SDD-IIoT can achieve security comparable to that offered by “Quantum Key Distribution” (QKD) networks in practice, determined by the computational hardness of cracking Quantum Safe ciphers. The SDD-IIoT can save the industry 10s . . . $100s of billions (US dollars) per year, by exploiting low-cost FPGAs, providing a powerful incentive to innovate layer-3 of the Internet.

A method is presented for facilitating sales transactions by electronic media. A barcode or other design containing merchant seller information is attached to a decal, label or stamp sheet to enable electronic payment to a merchant seller's account. The decal sheet is made with an adhesive sufficient to allow the decal label once printed, to be attached to a personal object during the period of time for which a financial transaction might occur. The decal label is then removed from the decal label sheet and applied to the personal object provided by the merchant. Before the sales transaction can be consummated, the decal label information is scanned by the buyer's smartphone. Characteristics about the decal label are compared to characteristics about the decal label's information digitally stored on a computer database in question in order to validate the identity of the merchant seller. Once merchant seller's information is validated, the seller may be authorized to debit (or cause a charge) the buyer's electronic account in order to consummate the transaction or transactions. The seller's electronic merchant bank account may be similarly updated.
