Due to the unique architecture of cloud-computing systems, the methods for detecting and preventing DoS attacks are quite different from those used in traditional network systems. A main target for DoS attackers is the authentication protocol because it is considered a gateway to accessing cloud resources. In this work, we propose a cloud-based authentication protocol - one that securely authenticates the cloud user and effectively prevents DoS attack on the cloud-comput","authors_text":"Abdelkader Ouda, Luiz Fernando Capretz, Marwan Darwish","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2017-11-22T22:47:30Z","title":"Formal Analysis of an Authentication Protocol Against External Cloud-Based Denial-of-Service (DoS) Attack"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1711.09985","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:d4cb47fda25be3edc551a487e0753b54538baf3392c9f4a0e5b7d0d4a064e97b","target":"record","created_at":"2026-05-18T00:29:23Z","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":"6ccc28d61b194a502afbc2d1d09cbed271b66ab2c68136e6c71e3472830e5c84","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2017-11-22T22:47:30Z","title_canon_sha256":"c36bab48d4788e64f46da64695808ec7b27eced44833526b5c829d6e0a565a49"},"schema_version":"1.0","source":{"id":"1711.09985","kind":"arxiv","version":1}},"canonical_sha256":"1e998da2b944155c974eb306b3643d085e760f700c750586e51f3b7e9910278c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1e998da2b944155c974eb306b3643d085e760f700c750586e51f3b7e9910278c","first_computed_at":"2026-05-18T00:29:23.723867Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:29:23.723867Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1vyBuC+O1rOyk/GXiZVRqAzEnRon0OKXRNH8n7qZyyDp99D1a8RfiobfRGYpskUFkg46LpsQOd+FRhYOb8OsAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:29:23.724403Z","signed_message":"canonical_sha256_bytes"},"source_id":"1711.09985","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d4cb47fda25be3edc551a487e0753b54538baf3392c9f4a0e5b7d0d4a064e97b","sha256:bd20b60156d222449d49627a4f9002d6e4ef44b6aa0214de9809e48652637f6f"],"state_sha256":"f8039d68df22c03d36a86efa4a9cb620747d78308b3e2387644d9823daed9881"}
