Although prior studies have attempted to design ASIC accelerators to mitigate the overhead, their designs require excessive chip resources (e.g., areas) to contain and process massive data for FHE operations. We propose CiFHER, a chiplet-based FHE accelerator with a resizable structure, to tackle the challenge with a cost-effective multi-chip module (MCM) design. First, we devise a flexible core architecture whose c","authors_text":"Jaeyoung Choi, Jongmin Kim, Jung Ho Ahn, Sangpyo Kim","cross_cats":["cs.CR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AR","submitted_at":"2023-08-09T11:41:56Z","title":"CiFHER: A Chiplet-Based FHE Accelerator with a Resizable Structure"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2308.04890","kind":"arxiv","version":3},"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:f41ad01835bb8083a510e3c849758014359cc11af7068778abdd0960a014d011","target":"record","created_at":"2026-07-05T08:02:45Z","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":"be559dd69547401a40262d54a94b03e032ef0a62190c0aef3982f328a3780dcd","cross_cats_sorted":["cs.CR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AR","submitted_at":"2023-08-09T11:41:56Z","title_canon_sha256":"01d32ceba8e746d566e7ea07269a3a7c8c1717c9854e22a07e4b342c1da36854"},"schema_version":"1.0","source":{"id":"2308.04890","kind":"arxiv","version":3}},"canonical_sha256":"2725503cc68e19874c25ba72b9dd25a9675238b5ad71161de9fe21047948aec7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2725503cc68e19874c25ba72b9dd25a9675238b5ad71161de9fe21047948aec7","first_computed_at":"2026-07-05T08:02:45.323206Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:02:45.323206Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"xWWBXmEtQ4VOcQZ2LEiSwzfn/vcLy38FJeW35eXOOGmzIUCl3RI0tXf6l/ASq4eUNvXUzNC9l7mZIb//NDAqCg==","signature_status":"signed_v1","signed_at":"2026-07-05T08:02:45.323710Z","signed_message":"canonical_sha256_bytes"},"source_id":"2308.04890","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f41ad01835bb8083a510e3c849758014359cc11af7068778abdd0960a014d011","sha256:c13cee132ee93ecdfcaa3e0261df0671f4bc786bfae26c0ce19ace93e58efea5"],"state_sha256":"db6e0f50a309cbafc3acd5b36457117e441dad28f327c37f51ed8c6df712b0ef"}
