Kyber/Aigis-enc KEM decaps 恢复 shared secret + -> SHA-256(shared secret) 派生 AES-256-GCM key + -> 验证 manifest 签名 + -> AES-256-GCM 解密文件 + -> 校验 SHA-256 摘要 + -> 输出恢复目录 +``` + +## 2. KEM 文件级接口 + +可执行文件： + +```text +kyberandaigis-enc/kyber768_amd +``` + +密钥生成： + +```bash +./kyber768_amd \ + --api-kem-keygen \ + --batch 128 \ + --pk-out kem_pk.bin \ + --sk-out receiver_sk.demo_secret +``` + +封装： + +```bash +./kyber768_amd \ + --api-kem-encaps \ + --batch 128 \ + --pk-in kem_pk.bin \ + --ct-out kem_ct.bin \ + --ss-out ss_sender.demo_secret +``` + +解封装： + +```bash +./kyber768_amd \ + --api-kem-decaps \ + --batch 128 \ + --sk-in receiver_sk.demo_secret \ + --ct-in kem_ct.bin \ + --ss-out ss_receiver.demo_secret +``` + +正确性判断： + +```bash +cmp ss_sender.demo_secret ss_receiver.demo_secret +``` + +如果两端 shared secret 一致，则 KEM 文件级接口正确。前端不会直接把 shared secret 当明文密钥使用，而是执行： + +```text +AES-256-GCM key = SHA-256(shared secret) +``` + +随后用该 AES key 对文件内容进行加密和解密。 + +## 3. SIG 文件级接口 + +可执行文件： + +```text +mldsaandaigis-sig/mldsa65_amd +``` + +当前开发包中如果目录仍为 `amd_sig_anchor_results_20260605_031411`，最终改名为 `mldsaandaigis-sig` 后，需要同步更新前端后端路径。 + +签名： + +```bash +./mldsa65_amd \ + --api-sig-sign \ + --batch 128 \ + --msg-in manifest.payload.json \ + --pk-out sig_pk.bin \ + --sk-out sig_sk.demo_secret \ + --sig-out manifest.sig +``` + +验签： + +```bash +./mldsa65_amd \ + --api-sig-verify \ + --batch 128 \ + --msg-in manifest.payload.json \ + --pk-in sig_pk.bin \ + --sig-in manifest.sig +``` + +前端中被签名的对象不是单个文件本身，而是 `manifest.payload.json`。该 payload 包含文件名、密文路径、nonce、tag、SHA-256 摘要、KEM ciphertext 路径和算法配置等信息。这样可以一次性保护整个传输包的结构和文件完整性。 + +## 4. 安全包关键文件 + +一次成功运行会生成类似结构： + +```text +pack_xxx/ + manifest.json + kem/ + kem_pk.bin + kem_ct.bin + sig/ + manifest.payload.json + manifest.sig + sig_pk.bin + encrypted/ + *.enc + recovered/ + ... +``` + +关键含义： + +`manifest.json`：安全包主清单，记录算法配置、文件摘要、密文位置、KEM/SIG 后端信息和验证所需元数据。 + +`kem/kem_ct.bin`：KEM ciphertext，接收端使用私钥 decaps 后恢复 shared secret。 + +`sig/manifest.payload.json`：被 ML-DSA/Aigis-sig 签名的清单载荷。 + +`sig/manifest.sig`：manifest payload 的签名。 + +`encrypted/*.enc`：AES-256-GCM 加密后的文件密文。 + +`recovered/`：验证通过后恢复出的明文文件目录。 + +## 5. Batch/decomp 设计说明 + +本项目不强行使用单实例签名 CLI 作为主路径。原因是 ML-DSA/Aigis-sig 在 AMD ROCm 平台上存在更明显的资源压力，单实例或过重 kernel 容易受到 private segment、scratch、occupancy 等因素影响。 + +因此前端采用 batch/decomp 文件级接口作为实际应用路径： + +```text +batch 提供 GPU 并行吞吐 +decomp pipeline 降低单个签名路径的资源压力 +文件级 API 让前端能够真实调用 KEM/SIG 能力 +``` + +这也是项目的主要工程贡献之一：不是只给出 isolated benchmark，而是把 Kyber/Aigis-enc 和 ML-DSA/Aigis-sig 接成可演示、可验证、可扩展的 ROCm 后量子安全传输流程。

TPB, launch bounds, device buffer reuse, and ROCm trace/resource analysis. +- `sig_optimization/`: ML-DSA/Aigis-sig profiling and feature-matrix tooling for resource-aware signing on ROCm. +- `evidence/`: small result summaries and decision notes suitable for PR description, report tables, and defense slides. + +## Main Optimization Evidence + +KEM: + +- Kyber-768 keygen profiling shows the sample/XOF/rejection-sampling stage is the dominant bottleneck, about 70% of the pipeline time in the recorded run. +- Kyber-768 encaps improved from about 6.00M ops/s to about 7.10M ops/s after launch-bound tuning. +- Device buffer reuse improved continuous full-KEM throughput from about 1.93M to 2.05M instances/s in the recorded run. + +Signature: + +- The stable ROCm path uses a resource-aware decomp pipeline because monolithic/cached-style signing creates private-segment and scratch-pressure risk. +- Feature-matrix candidates include `adaptive`, `check8`, `check16`, `wave64_ctrl`, `cp_fuse`, `tail16_base`, `tail16_cp_fuse`, and `yhat_dup`. +- Local wins exist, for example ML-DSA-65 independent batch=16384 with `cp_fuse` reached 1.3625x speedup, and Aigis-sig3 independent batch=16384 with `wave64_ctrl` reached 1.4200x. +- Conservative selected builds keep the base decomp pipeline when no candidate satisfies the no-regression rule across all measured cells.

+### 11.2 Kernel 级瓶颈判断 + +对 pipeline keygen 而言，kernel trace 与程序内 profile 一致： + +```text +batch_keygen_warp_sample_kernel: 5.130 ms +batch_polyvec_matvec_kernel: 0.485 ms +batch_invntt_kernel total: 0.334 ms +batch_ntt_kernel total: 0.303 ms +pack pk/sk/finalize total: 0.565 ms 左右 +``` + +结论： + +> ROCm kernel trace 进一步确认，Kyber-768 pipeline keygen 的主要热点是 `batch_keygen_warp_sample_kernel`，即采样/XOF/拒绝采样路径。NTT、inverse NTT、matvec 和 packing 的耗时均显著低于 sample。因此下一步优化重点应继续围绕采样路径，而不是优先重写 NTT。 + +### 11.3 HIP API Trace + +Top HIP APIs by total time： + +| HIP API

`hipLaunchKernel` 总耗时约 2.147 ms，25 次调用，平均约 0.086 ms；对大 batch 影响可接受，但对小 batch 会明显影响端到端效率。 + +### 11.4 从 ROCm Trace 得出的优化建议 + +1. **sample kernel 是第一优化目标** + - 重点分析 `batch_keygen_warp_sample_kernel` 中 SHAKE/XOF、拒绝采样、噪声采样的线程协作方式。 + - split sample 已经证明会负优化，因此后续应优先考虑保持数据局部性与减少全局内存中间写回。 + +2. **减少端到端内存搬运** + - `hipMemcpy` 在 API trace 中占比较高。 + - 后续多文件可信流转平台应尽量复用 device buffer，避免每批数据重复分配和拷贝。 + +3. **减少小 batch 下 launch/sync 开销** + - `hipLaunchKernel` 与 `hipDeviceSynchronize` 对小 batch 会放大。 + - 前端/工作流层应聚合多文件任务，使用 batch 队列提高 GPU 利用率。 + +4. **按路径分别优化** + - serial keygen/encaps/decaps 是当前 best-throughput

`batch_keygen_warp_sample_kernel` 耗时 5.101 ms，仍是 pipeline keygen 中最大单项。 + - 该 kernel 使用 VGPR=152、Scratch=304、LDS=512，说明 sample 路径也存在较高寄存器压力，但比 monolithic serial kernel 的 scratch 小得多。 + +2. **monolithic serial kernel 存在寄存器/栈压力** + - keypair/encaps/decaps serial kernel 均使用 VGPR=184。 + - encaps/decaps scratch 超过 16KB，后续可考虑拆出局部大数组、减少设备函数局部状态、复用全局/共享缓冲，或针对 encaps/decaps 建立更细粒度 batch
