Abstract
A secure inter-cloud authentication system uses time-synchronized tokens for verifying user access requests across multiple cloud providers. By generating an authentication token that includes a timestamp and time-based one-time password (TOTP), synchronized with a Network Time Protocol (NTP) server, the system ensures that each access request is valid only within a specific time window. When a user requests data access, the token is verified by each participating cloud provider against the synchronized timestamp, allowing secure, time-sensitive validation across platforms. An identity provider (IdP) manages token issuance and synchronization, centralizing the authentication process while maintaining precise time alignment across clouds. This time-sync verification reduces the risk of replay attacks and ensures that only legitimate requests are processed, enabling secure, synchronized data access in multi-cloud environments. The invention provides a scalable, high-security solution for cross-cloud authentication, with strict time-based validation enhancing protection against unauthorized access.
