はじめに

2025年に開催された国外の各学会において、秘密計算（特に準同型暗号）・耐量子計算機暗号の各方式の発表件数をカウントします。
ただし、以下を条件とします

中身は確認せずにタイトルから方式を判断する（30秒以内に判断できない場合は「不明」とする）
対象とする学会は、以下とします（概ね、開催時期がその年で早い順）
- FSE: Fast Software Encryption
- NDSS: Network and Distributed System Security
- RWC: Real World Crypto
- Eurocrypt
- PKC: Public Key Cryptography
- IEEE S&P: IEEE Symposium on Security and Privacy
- IEEE Euro S&P: IEEE European Symposium on Security and Privacy
- USENIX: USENIX Security
- Crypto
- ESORICS: European Symposium on Research in Computer Security
- ACM CCS: ACM Conference on Computer and Communications Security
- CHES: Conference on Cryptographic Hardware and Embedded Systems
- Asiacrypt

こうしないとさすがに大変すぎるので・・・．

今回は、主要な学会に絞って、秘密計算・耐量子計算機暗号の発表に関して調査しました

耐量子計算機暗号に関しては、格子がダントツで多くて、ついで符号ベース、多変数多項式と同種は同じぐらいでした
その他に含まれる論文は、実際の通信に応用したものなどがあり、耐量子計算機暗号の実用化がいよいよ迫ってきていることを感じました

また、準同型暗号に関しては、CKKS と TFHE が抜けているのは、毎年の傾向ですね
2方式で差がついたのは、主に CHES ですので、そのような意味で、理論は CKKS、実装はTFHEだった2025年だったと思います
