Multi-authority steered targets (MAST) is a method used in VPN protocols to facilitate enhanced privacy and security. It operates by enabling selective disclosure of the routing path. This means that a VPN user utilizing MAST can control and choose which authorities (usually represented as nodes or servers) have access to certain routing information, thus improving the overall privacy of the connection.
- The Tor network: MAST can be used in the Tor network to conceal the full path of the user’s internet traffic, revealing only necessary segments to each node.
- VPN connections: MAST can be integrated into VPN protocols to enhance user privacy by controlling the disclosure of routing paths.
Advantages and disadvantages of MAST
- Enhanced privacy: MAST helps improve user privacy by concealing the complete routing path from any single authority.
- Reduced surveillance: By selectively disclosing routing information, MAST reduces the potential for surveillance by any compromised node.
- Complexity: MAST introduces additional complexity into the VPN protocol, which might demand more processing power.
- Network speed: The added complexity may impact network speed and performance, although it is not significant in most cases.
- Ensure your VPN provider supports MAST for an enhanced level of privacy.
- Understand the implications of selective routing information disclosure to maximize the benefits of MAST.
