 # Attestation Agent
 
 Attestation Agent (AA for short) is a service function set for attestation procedure
-in Confidential Containers. It provides kinds of service APIs that need to make
-requests to the Relying Party (Key Broker Service) in Confidential Containers,
-and performs an attestation and establishes connection between the Key Broker Client (KBC)
-and corresponding KBS, so as to obtain the trusted services or resources of KBS.

-Current consumers of AA include:

-- [image-rs](../image-rs)
+in Confidential Containers.
 
 ## Components
 
-The main body of AA is a rust library crate, which contains KBC modules used to communicate
-with various KBS. In addition, this project also provides a gRPC service application,

-## Supported KBC modules
-
-AA provides a flexible KBC module mechanism to support different KBS protocols required to make the communication between KBC and KBS. If the KBC modules currently supported by AA cannot meet your use requirement (e.g, need to use a new KBS protocol), you can write a new KBC module complying with the KBC development [GUIDE](docs/kbc_module_development_guide.md). Welcome to contribute new KBC module to this project!
