This topic provides detailed information about the main features, scenarios, and configuration processes of PCA, OpenID Connect (OIDC), and PKCS#7 federated credential providers in the M2M federation credential capability of IDaaS.
PCA federated credential provider
Private Certificate Authority (PCA) is a fully managed private certificate authority management service designed to create and manage private digital certificates for internal enterprise use.
Core features
Internet of Things (IoT) and Internet of vehicles device security: Provisions unique digital certificates for devices to implement device identity authentication and bidirectional secure communication (such as MQTT platform communication), effectively preventing unauthorized access and data tampering.
Software and firmware signing: Issues signing certificates for software/firmware to ensure legitimacy verification and tamper-proofing capabilities (for example, Launch Tech's charging pile device firmware verification).
Enterprise internal resource protection: Protects internal resources such as servers, applications, and containers to meet regulatory compliance requirements (such as data security requirements in finance and healthcare industries).
Cross-account and region certificate management: Supports cross-account sharing of root CA and region publishing CA, simplifying large-scale certificate deployment (for example, StubHub's PKI architecture reconstruction during cloud migration).
Scenarios
PCA federated credentials in M2M scenarios solve the security interoperability challenges between heterogeneous systems through unified device identity management and cross-domain trust mechanisms. They are particularly suitable for:
Large-scale device interconnection.
Cross-organization collaboration environments.
Industries with high compliance requirements.
Configuration process
If an enterprise or organization has a self-built PCA, you can choose to create a federated credential provider. Using the signing capability of PCA to sign JWT Tokens, when calling the IDaaS authorization server Token endpoint, select the PCA federated credential capability, provide the corresponding root certificate, intermediate certificate list, and client certificate to complete the entire call chain and obtain the Access Token issued by IDaaS.
OIDC federated credential provider
OIDC is the abbreviation for OpenID Connect protocol, which is widely used in scenarios such as Single Sign-On (SSO), cross-organization identity federation, third-party identity provider integration, and API secure calls.
Core features
The OIDC protocol provides an identity authentication layer based on OAuth 2.0, allowing client services to securely verify user identity and obtain user information.
Scenarios
In M2M scenarios, if the user's client service is deployed in the following environments:
Kubernetes POD.
Alibaba Cloud ACK cluster (supporting RRSA mode).
GitHub workflow.
CI/CD pipeline.
Azure VM.
Google Cloud Compute Engine.
Configuration process
Obtain OIDC Token from container or cloud server.
Select OIDC federated credential capability when calling the IDaaS authorization server Token endpoint.
Provide the corresponding verification public key.
Complete the call chain to obtain Access Token.
PKCS#7 federated credential provider
PKCS#7 is a fundamental standard in Public Key Infrastructure (PKI), widely used in scenarios requiring data integrity and confidentiality.
Core features
Financial transaction security: Used for signing and encrypting bank transaction data to ensure the authenticity and integrity of transaction instructions (for example, banks protect sensitive operations such as transfers and payments through PKCS#7).
Electronic government document signing: Government agencies use PKCS#7 for digital signatures on electronic documents, giving them legal effect equivalent to physical seals (such as electronic official documents, legal contracts, and identity authentication).
Data signing and encryption: PKCS#7 supports digital signing and encryption of messages, widely used in scenarios requiring verification of data sources and prevention of tampering (such as file exchange between enterprises and software distribution). Its formats (such as .p7b/.p7c) can contain multiple signatures and certificates, suitable for complex trust chain management.
Scenarios
Applicable to client services in the following cloud server environments:
Alibaba Cloud ECS/ECI.
Amazon EC2.
Configuration process
Obtain PKCS#7 signature from cloud server metadata signature endpoint.
Select PKCS#7 federated credential capability when calling the IDaaS authorization server Token endpoint.
Provide the corresponding verification root certificate.
Complete the call chain to obtain Access Token.
Summary
The three federated credential provider capabilities provided by IDaaS can meet M2M security authentication requirements in different scenarios. Enterprises can choose the most suitable federated credential solution based on their business scenarios and technical architecture.
