Hardware acceleration of HE is crucial as software implementations are very slow. In this paper, we present design methodologies for building a programmable hardware accelerator for speeding up the cloud-side homomorphic evaluations on encrypted data. First, we propose a divide-and-conquer technique that enables homomorphic evaluations in a large polynomial ring $R_{Q,2N}$ to use a hardware accelerator that has been built for the ","authors_text":"Ahmet Can Mert, Aikata, Donghoon Yoo, Sujoy Sinha Roy, Sunmin Kwon, Yongwoo Lee, Youngsam Shin","cross_cats":["cs.AR"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CR","submitted_at":"2022-10-11T14:21:54Z","title":"Medha: Microcoded Hardware Accelerator for computing on Encrypted Data"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2210.05476","kind":"arxiv","version":2},"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:d2a186f5ca231eaea560e0af54277639f49b70939484f79fc53049befc736c44","target":"record","created_at":"2026-07-05T05:05:51Z","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":"75d369311cddbd05d04b3a667e0520e5c049d9440a23c7ea887021ffecde6a40","cross_cats_sorted":["cs.AR"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CR","submitted_at":"2022-10-11T14:21:54Z","title_canon_sha256":"79b5a0f391eacac44472f301720dcf5b646481bd2cfe061a318b3ac042fe5fba"},"schema_version":"1.0","source":{"id":"2210.05476","kind":"arxiv","version":2}},"canonical_sha256":"e662df03f7f5cb87bf2d00acfc706b6a69046afd9450cd6b6b878d1ad7683b41","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e662df03f7f5cb87bf2d00acfc706b6a69046afd9450cd6b6b878d1ad7683b41","first_computed_at":"2026-07-05T05:05:51.557638Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:05:51.557638Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+sx3icR0gKFR7tB5sFR+pthEvupBSoEWBbOP1o3M2FCSbeypx1783PfGZChC5lHAIFmsYq+M948Q3zDdHD59AQ==","signature_status":"signed_v1","signed_at":"2026-07-05T05:05:51.558034Z","signed_message":"canonical_sha256_bytes"},"source_id":"2210.05476","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d2a186f5ca231eaea560e0af54277639f49b70939484f79fc53049befc736c44","sha256:289519c45597f7f72babd450329f574b7244f4c8de6d22f3c69cd4791c1bf386"],"state_sha256":"d08f8c73209a4487319061473dd653b2acfd8384f2877e9a088b98913cebf8ef"}
