9. SECURE MULTIPARTY COMPUTATION

10. SECUREMULTIPARTYCOMPUTATION
• SMC is a set of techniques and algorithms that
allows two or more non-mutually trusted parties, to
perform some kind of computation over a data set,
while keeping their respective information private
• No need of a trusted third party
• Each party holds some kind of private input
• Each player only learns:
– the output of the computation
– the information that can be inferred from their own inputs

11. SECUREMULTIPARTYCOMPUTATION
• Examples
– Electronic Voting
– Biding contracts and
auctions
– Rankings
– Statistics

12. SECUREMULTIPARTYCOMPUTATION
• Examples
– Electronic Voting
– Biding contracts and
auctions
– Rankings
– Statistics

13. CASE STUDIES:
SLOT TRADING AND DELAY REPORTS

14. SLOT TRADING AND DYNAMIC LANDING QUEUES
• A secure auction process:
– The auctioneer is a Secure Multiparty
Computation Engine (SMC Engine).
– All the participants are Semi-honest parties
• Primary and Secondary Slot Trading Markets
• Strategic and Operational Slot Trading
Transactions

15. SLOT TRADING AND DYNAMIC LANDING QUEUES

16. ANALYSIS OF DELAY REPORTS
• A benchmarking process:
– Reports delay causes using cleared information coming from different
participants, securely merged in order to achieve additional
knowledge about causes of delays and their evolution through time
– All the participants are Semi-honest parties
• Preprocessed info in single analysis tables (route + time
window)
• 99 different delay causes according to the IATA classification
• Participants:
– Pilots, airline representatives, ATC officers, Network Manager, airport
representatives and handling organizations

18. LEGAL CHALLENGES IN A REAL SCENARIO

19. INNOVATION BASED LEGAL CHALLENGES
• Who is to blame if a new service or product
fails in a “go-live” stage? The developers? The
Testers? The Quality Assurance people? The
Authorizing party?

20. TECHNOLOGY BASED LEGAL CHALLENGES
• Cloud usage
• Who is to blame if the system is not used
correctly? Who is to blame if a party inputs
false data?
• How to certify the SMC process? How to
certify the SMC framework? The encryption
and protocols used? The data transmission?
• Who is the owner of the secret-shares?

21. CASE STUDIES LEGAL CHALLENGES
• Change of market regulation
• Coordination for an international law
• Access restrictions
• Authorizations
• Referee
• Database access in parties premises
