What is eduroam?

2

eduroam (education roaming) is the secure, world-wide roaming access service developed for the international research and education community.

eduroam allows students, researchers and staff from participating institutions to obtain Internet connectivity across campus and when visiting other participating institutions by simply opening their laptop.

Who operates eduroam• The eduroam service started as a pilot under the

auspices of TERENA.• 4 regional operators• About 50 countries worldwide– 7 members in Asia Pacific

• GeGC (Global eduroam Governance Committee)

has been organized (2010).– 7 voting members: EU(3), US, CA, AP(2)– “Compliance Statement” compilation is under way.

• service definitions, technical standards

eduroam deployments in Asia Pacific

• Hosting by a nearby country works well as an incubator.• Hosting is quite beneficial for countries having a small

number of institutions. 4

eduroam JP• National eduroam operation and promotion– 27 institutions (2% of 1,200) joined (Dec. 2011)

• 17 (2010), 9 (2009)– Tutorial & technical documents

• R&D– Easy deployment and operation– Location privacy, etc.

• Collaboration with commercialW-ISPs– eduroam on commercial hotspots – Shared hotspots on campus– New architecture and business models for next-

generation commercial / academic WLAN services

eduroam / ISP collaboration

• Livedoor, an ISP in Japan, provides eduroam service on their commercial hotspots– 130+ in-door APs at cafes, conference sites and some

large shops in and around Tokyo– 2,200+ out-door APs on power poles in central Tokyo• eduroam-livedoor is now available on the streets

– provides Campus Network solution with eduroam

• Commercial WLAN service using univ. APs– shared AP, experimental

• Negotiations are under way with some other ISPs / carriers

eduroam in disaster-affected campuses• Borderless eduroam helped suffering staff

– Nomadic network in temporary evacuation campus• Tohoku University faced the big earthquake in March.

– Many buildings were severely damaged. – Staff moved to other buildings where networks are operated by different

departments.– eduroam is an effective rescue for them to use network --- Inter-

department roaming network

Network ID

• Problems– Difficulties in large-scale RADIUS deployment

• 1200 institutions in Japan → 1200 branches in RADIUS tree– Laborious eduroam connection / management work

• Our solutions– Federated Delegate Authentication System (DEAS)

with centralized/clustered RADIUS server• remove RADIUS IdP at each institution• Federation using Shibboleth SSO• simplify RADIUS tree (→ higher stability)

– Web-based eduroam IdP / SP management system• simplify connection and administration at both the

eduroam JP office and each institution

Federated Delegate Authentication System

• Account Issuer as a Shibboleth SP of Japan’s GakuNin federation (f.k.a. UPKI federation)

• Centralized / Clustered eduroam IdP to simplify the RADIUS proxy tree

• 3 types depending on the needs and federation level

• Authenticated access with pseudo-anonymized, fixed-term, and traceable roaming IDs

Before & After DEAS• Huge RADIUS tree can be replaced by single RADIUS which

works as an SP for member institutions
