Crosswalk
How Post-Quantum Cryptography is matched to the patent classifications. The entries below were chosen for it; each stands for itself and everything beneath it in the scheme, 2 Cooperative entries in all. A patent family counts when any of its codes, in either scheme and at any office, falls under one of them. Codes since retired are placed under the entries that replaced them.
| Entry | Title in the scheme | Why it is chosen | CPC codes | IPC codes | Documents |
|---|---|---|---|---|---|
| H04L9/3093 | Public key, i.e. encryption algorithm being computationally infeasible to invert or user's encryption keys not requiring secrecy involving Lattices or polynomial equations, e.g. NTRU scheme | Lattice-based public-key cryptography | 1 | none | 3,864 |
| H04L9/304 | Public key, i.e. encryption algorithm being computationally infeasible to invert or user's encryption keys not requiring secrecy based on error correction codes, e.g. McEliece | Code-based public-key cryptography, e.g. McEliece | 1 | none | 1,794 |
CPC and IPC codes are the codes in use on patent documents, at any office, that fall under the entry. Documents is the larger of the two schemes' counts of documents carrying one of them. An entry with no IPC codes can be told apart only in the Cooperative scheme.
The Cooperative codes in use that count towards Post-Quantum Cryptography: 2 codes on 5,658 documents. The full crosswalk is in the cpc-to-capability.csv download.
| Code | Title | Under entry | How placed | Documents |
|---|---|---|---|---|
| H04L9/3093 | Public key, i.e. encryption algorithm being computationally infeasible to invert or user's encryption keys not requiring secrecy involving Lattices or polynomial equations, e.g. NTRU scheme | H04L9/3093 | In the scheme | 3,864 |
| H04L9/304 | Public key, i.e. encryption algorithm being computationally infeasible to invert or user's encryption keys not requiring secrecy based on error correction codes, e.g. McEliece | H04L9/304 | In the scheme | 1,794 |
