However, the fundamental challenge of FHE is its inefficiency, due primarily to the underlying polynomial computations with high computation complexity and extremely time-consuming ciphertext maintenance operations. To tackle this challenge, various FHE accelerators have recently been proposed by both research and industrial communities. This paper takes the first initiative to conduct a systematic study on the 14 FHE accelerators -- cuHE/cuFHE, nuFHE, HEAT, HEAX, HEXL, HEXL-FPGA, 100$\\times$, F1, Cra","authors_text":"Jinbin Hu, Junxue Zhang, Kai Chen, Liu Yang, Xiaodian Cheng, Ximeng Liu","cross_cats":["cs.AR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2022-12-04T00:45:55Z","title":"SoK: Fully Homomorphic Encryption Accelerators"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2212.01713","kind":"arxiv","version":4},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:da820272595396ea2e4675d1cc04621fb5727b32b6843bb481a4d7b3268fafbe","target":"record","created_at":"2026-07-05T10:08:10Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"bdd1079ff97074c3cda878d59df85cc86371a7abf5851fe97968680e45114dfc","cross_cats_sorted":["cs.AR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2022-12-04T00:45:55Z","title_canon_sha256":"862b430743ec8d28f5784b27204187bc15663b12a0e8319fe74d96b7d7628847"},"schema_version":"1.0","source":{"id":"2212.01713","kind":"arxiv","version":4}},"canonical_sha256":"9b64d30451860e2cc1544ad0fc157c358c2bb1898a1ca0b41b31e2026112f0b1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9b64d30451860e2cc1544ad0fc157c358c2bb1898a1ca0b41b31e2026112f0b1","first_computed_at":"2026-07-05T10:08:10.708393Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:08:10.708393Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"f1TgkoesMZY5jEpV77f8B1s6HM7CdbSxpAjaOD/bd5mSdhRTfV1T3jTfarMZq4MEgsplGs3IMMXFUWZKu4ucBA==","signature_status":"signed_v1","signed_at":"2026-07-05T10:08:10.708979Z","signed_message":"canonical_sha256_bytes"},"source_id":"2212.01713","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:da820272595396ea2e4675d1cc04621fb5727b32b6843bb481a4d7b3268fafbe","sha256:e4b7a333a5f5080d82db85010b98c426de3962846201475e9c65ae722c993719"],"state_sha256":"35b0245886aa41ef4b48d5dad154daae7e437b7581c605ec49dceca2a158af79"}
