A Secure Access Module (SAM), also known as a Secure Application Module, is a piece of cryptographic hardware typically used by smart cardcard readers to perform mutual key authentication.[1][2][3] SAMs can be used to manage access in a variety of contexts, such as public transport fare collection and point of sale devices.
Removable SAM: This form factor resembles a standard Subscriber Identification Module (SIM) card. It plugs into a dedicated SAM slot within the smart card reader.
Embedded SAM: This form factor integrates the SAM functionality directly onto the printed circuit board (PCB) of the reader system. The SAM component is typically housed within a secure enclosure soldered onto the PCB.
Componentsedit
A typical smart card reader system generally consists of the following key components:
Microcontroller (MCU): This acts as the central processing unit (CPU) of the reader system. It manages various tasks such as protocol handling, data flow control, and data interpretation.
Reader Integrated Circuit (Reader IC): This specialized chip facilitates communication between the SAM and the contactless smart card using radio frequency (RF) interface protocols.
Integration and functionalityedit
By integrating a SAM into the reader system, the security functionalities are centralized and offloaded from the MCU. The SAM assumes responsibility for:[4]
Key Management: Secure storage and management of cryptographic keys, including master keys and application keys derived from them.
Cryptography: Performing various cryptographic operations such as encryption, decryption, and digital signing to ensure data confidentiality and integrity.
Mutual Authentication: Facilitating a two-way authentication process between the smart card and the reader system to verify the legitimacy of both parties before allowing any communication to proceed.
Secure Messaging: Enabling secure communication between the SAM and the host system by encrypting and authenticating data packets.[5]
