暗号技術入門 第3版
結城浩
Reason: With hashing and signatures as your cryptographic foundation, see how they play out across a real identity lifecycle. This book traces registration through login, recovery, and account closure as one continuous flow, moving from single-service authentication/authorization to identity-provider federation.

OpenID Connect入門
土岐孝平
Reason: Grasping the whole picture of ID management—from signup to logout to identity federation—in plain language lays the groundwork for the more specialized, detailed implementation covered by the OAuth 2.0 and OIDC protocol specs. Having organized the relationships among identity verification, authentication, and session management in Getting Started with Digital Identity makes it easier to place the authorization code flow and token validation covered in OpenID Connect Primer.

OAuth徹底入門
Justin Richer、Antonio Sanso
Reason: Once you hold the shape of ID management and identity federation, step into the implementation of the authorization protocol at its core. Working through OAuth 2.0's grants and flows in code clarifies pitfalls like token leakage and redirect URI tampering from first principles.
