Among known approaches, server-aided revocation yields a promising solution, because it allows to outsource the major workloads of system users to a computationally powerful third party, called the server, whose only requirement is to carry out the computations correctly. Such a revocation mechanism was considered in the settings of identity-based encryption and attribute-based encryption by Qin et al. (ESORICS 2015) and Cui et al. (ESORICS 2016), respectively.\n  In this work, we consider the ser","authors_text":"Huaxiong Wang, Juanyang Zhang, Khoa Nguyen, San Ling","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2018-01-24T02:48:50Z","title":"Server-Aided Revocable Predicate Encryption: Formalization and Lattice-Based Instantiation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1801.07844","kind":"arxiv","version":1},"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":"sha256:301efe2486451bc781c924ea5ee31cceac7e7a6c147c1a27bbbbb1041ea808a9","target":"record","created_at":"2026-05-18T00:25:10Z","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":"808921e5714eb45eaebad5d396a6dfbd53b7d1b05ee955eeffe00d4bfbb10f18","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2018-01-24T02:48:50Z","title_canon_sha256":"d2c6df7df7d648f8896d540de52345cb5e0136eade1dc74c7b0d7c0147f03450"},"schema_version":"1.0","source":{"id":"1801.07844","kind":"arxiv","version":1}},"canonical_sha256":"8a1547b444c52dc8a469e6f5c5377e81368d3d74453cd91ffd7dc0571fdb7afe","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8a1547b444c52dc8a469e6f5c5377e81368d3d74453cd91ffd7dc0571fdb7afe","first_computed_at":"2026-05-18T00:25:10.717840Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:25:10.717840Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"P8QJerwJsqsVF3M20HnDH5K/wEf4kWT4JUOh0xRJ0GfL71QFcteTsqFjRGpCNfObR7A0YX9oifu446g8QyFiDg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:25:10.718441Z","signed_message":"canonical_sha256_bytes"},"source_id":"1801.07844","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:301efe2486451bc781c924ea5ee31cceac7e7a6c147c1a27bbbbb1041ea808a9","sha256:cf6ea3b53623b00e9440f34291f38546ff3b3020da1f92a0e9abd9fc07339943"],"state_sha256":"18ed166202a648858bdacedbcb9c4acdc1f3ed35d787740bf11012a379fa5ce8"}
