ETSI Quantum-Safe Cryptography
If NIST answers "which algorithms?", ETSI answers "how do we migrate?". The ETSI Quantum-Safe Cryptography Working Group, sitting under TC CYBER, leads on migration strategy, hybrid key exchange, and crypto-agility — and co-runs the field's flagship annual conference. It does not design algorithms; that remains NIST's role.
Where ETSI sits
ETSI is the European Telecommunications Standards Institute, but its cybersecurity work reaches far beyond Europe and telecoms. The Quantum-Safe Cryptography (QSC) Working Group operates within TC CYBER, ETSI's cybersecurity technical committee. Its remit is the practical, organizational side of the transition rather than the mathematics of the schemes themselves.
What the QSC WG focuses on
- Migration guidance — how organizations should plan and sequence a move to quantum-safe cryptography. See Migration.
- Hybrid mechanisms — combining classical and post-quantum primitives so protection holds if either part survives. See Hybrid.
- Crypto-agility — building systems that can swap algorithms without re-architecture. See Crypto-Agility.
- Quantum-safe protocols — specifying how quantum-safe primitives slot into real protocol flows.
Representative outputs
ETSI publishes technical reports (TR) and technical specifications (TS). Key documents from the QSC WG include:
| Type | Document | Theme |
|---|---|---|
| Technical Report | TR 103 619 (2020-07) | Migration strategies and recommendations to quantum-safe schemes |
| Technical Specification | TS 103 744 (2025/2026 update) | Quantum-Safe Hybrid Key Establishment |
| Technical Report | TR 103 949 (2023-05) | QSC migration — C-ITS use case |
| Technical Report | TR 103 966 (2024-10) | Hybrid-scheme deployment considerations |
The pattern is consistent: ETSI documents tell you how to adopt and combine standardized primitives safely, not how to build new ones.
The ETSI/IQC conference
ETSI co-runs the annual ETSI/IQC Quantum-Safe Cryptography conference with the Institute for Quantum Computing. It is one of the field's principal venues, bringing together standards bodies, regulators, vendors, and researchers to coordinate the transition — a useful pulse-check on where consensus is forming. The 2026 ETSI/IQC Quantum-Safe Cryptography conference took place on 16–18 June 2026 in Ottawa, Canada.
ETSI vs NIST — complementary roles
| Aspect | NIST | ETSI QSC WG |
|---|---|---|
| Algorithm design | Yes | No |
| Migration & agility guidance | Some (e.g. transition reports) | Core focus |
| Hybrid emphasis | Supports hybrid | Strong, practical focus |
| Geographic center | US | Europe (global reach) |
How to use ETSI material
When you have decided which algorithms to adopt (from NIST/IETF), ETSI's reports help you decide how: how to phase the rollout, where hybrid is warranted, and how to keep the estate agile for the next change. This makes ETSI especially valuable to architects and migration program owners.

ETSI 量子安全密码
如果说 NIST 回答的是"用哪些算法"，那么 ETSI 回答的是"如何迁移"。隶属 TC CYBER 的 ETSI 量子安全密码工作组在迁移策略、混合密钥交换与密码敏捷性上引领方向，并联合主办本领域的年度旗舰大会。它不设计算法，那仍是 NIST 的职责。
ETSI 的定位
ETSI 是欧洲电信标准化协会，但其网络安全工作的影响远超欧洲与电信范畴。量子安全密码（QSC）工作组运作于 ETSI 网络安全技术委员会 TC CYBER 之下。其职责是迁移中务实的、组织层面的事务，而非算法本身的数学。
QSC 工作组的聚焦点
- 迁移指南，组织应如何规划并排序向量子安全密码的迁移。详见 迁移。
- 混合机制，结合经典与后量子原语，只要其一存续即可维持保护。详见 混合。
- 密码敏捷性，构建无需重构即可更换算法的系统。详见 密码敏捷性。
- 量子安全协议，规范量子安全原语如何嵌入真实协议流程。
代表性成果
ETSI 发布技术报告（TR）与技术规范（TS）。QSC 工作组的主要文件包括：
| 类型 | 文件 | 主题 |
|---|---|---|
| 技术报告 | TR 103 619（2020-07） | 向量子安全方案的迁移策略与建议 |
| 技术规范 | TS 103 744（2025/2026 更新） | 量子安全混合密钥建立 |
| 技术报告 | TR 103 949（2023-05） | QSC 迁移，C-ITS 用例 |
| 技术报告 | TR 103 966（2024-10） | 混合方案部署考量 |
模式始终一致：ETSI 文件告诉你如何安全地采用与组合已标准化的原语，而非如何构建新原语。
ETSI/IQC 大会
ETSI 与量子计算研究所联合主办年度 ETSI/IQC 量子安全密码大会。这是本领域的主要平台之一，汇聚标准组织、监管机构、厂商与研究者协调迁移进程，是判断共识走向的有用风向标。2026 年 ETSI/IQC 量子安全密码大会已于 2026 年 6 月 16 至 18 日在加拿大渥太华举行。
ETSI 与 NIST 互补的角色
| 方面 | NIST | ETSI QSC WG |
|---|---|---|
| 算法设计 | 是 | 否 |
| 迁移与敏捷性指南 | 部分（如迁移报告） | 核心聚焦 |
| 对混合的重视 | 支持混合 | 务实而强烈 |
| 地理中心 | 美国 | 欧洲（全球适用） |
如何使用 ETSI 材料
当你已（依据 NIST/IETF）决定采用哪些算法后，ETSI 的报告帮你决定如何采用：如何分阶段推进、何处宜用混合、如何让整个体系对下一次变更保持敏捷。这使 ETSI 对架构师与迁移项目负责人尤为有价值。
