Core Insights - The article discusses the increasing demand for convenience and security in cross-platform services due to deep internet penetration and rapid digital technology iteration. The Xiaotian Interconnect communication platform enhances user experience through a comprehensive Single Sign-On (SSO) mechanism, allowing "one login for all services" [1] Group 1: Single Sign-On Core Process - When a user first accesses services under Xiaotian Interconnect, the system checks if they have logged in at the authentication center. If not, they are redirected to a unified authentication page for login, generating a Token (e.g., JWT) for secure transmission without server session storage [3] - After obtaining the Token, users can access other services without re-entering credentials, as the browser carries the Token for verification at the authentication center [3] Group 2: Xiaotian Genie Integration - Developers registering third-party applications on the Xiaotian Genie platform receive automatically assigned keys and credential information, ensuring secure application access through high-strength encryption algorithms [4] - Upon clicking an application entry, the system triggers an automated redirection to check the user's login status, issuing a ticket upon successful authentication that contains detailed user information for personalized service [5] - The front end sends the ticket to the back end for validation, automatically completing the login process and assigning corresponding permissions based on user information [6] Group 3: Cross-Platform Authentication Information Conversion - After logging in with the ticket, Xiaotian Genie forwards the user request to a third-party application, converting authentication information to the required format for seamless integration, such as mapping to OAuth 2.0 parameters [7] Group 4: Technical Implementation and Security Assurance - Xiaotian Interconnect employs multiple technical measures for stable operation, including HTTPS protocol and SSL/TLS encryption for secure transmission of sensitive information [9] - The collaboration of Token for quick verification and ticket for complex permission control enhances authentication efficiency and flexibility [9] - Dynamic permission mapping through custom interfaces allows for compatibility with different platform authentication standards [9] Group 5: Advantages, Challenges, and Future Plans - The SSO mechanism simplifies user operations and enhances platform service integration, reducing application access costs and achieving ecosystem openness similar to WeChat Work and DingTalk [11] - Ongoing challenges include cross-platform compatibility and credential security management, with plans to introduce AI risk identification technology for real-time monitoring of credential usage anomalies [11] - Future exploration includes standardized protocol adaptation to improve third-party application integration efficiency, aiming to provide a safer and more convenient digital service experience for users [11]
