Editing P2p mobile carriers (section)

The AKA protocol in the mobile system can be extended to support shared access to a mobile plan with an untrusted third-party.

A simple protocol that relays authentication messages between a remote mobile device and an MsC is an example, but one that is vulnerable to packet sniffing, session disruption, and abuse.

To defeat packet sniffing, a number of options were proposed. They include: variations on AKA authentication that support public key cryptography; End-to-end encryption at the application level, or between users in the same system; VOIP applications; SIM authentication oracles; Secret contracts; And lastly, physical distance to make packet sniffing more difficult.

To prevent session disruption a novel technique can be used to detect bad behaviour. Once detected, an offending party can be punished through a smart contract. Abuse against a plan is prevented by applying access controls and enforcing them with trusted computing.
