Technical details and manufacturing context for Encryption/Decryption Unit

Definition
The Encryption/Decryption Unit is a specialized hardware module embedded within Access Control Units that implements cryptographic algorithms to encrypt sensitive data (such as credentials, access logs, and communication packets) before transmission and decrypt received data for processing. It ensures data confidentiality, integrity, and authentication in access control systems by employing symmetric or asymmetric encryption techniques.
Working Principle
The unit receives plaintext data from the Access Control Unit's processor, applies encryption algorithms (e.g., AES, RSA) using stored cryptographic keys to generate ciphertext for secure transmission. For incoming data, it decrypts ciphertext back to plaintext using corresponding keys. It typically includes a cryptographic processor, secure key storage, and interfaces for data I/O.
