S.S.C.P.® Standard

logo SSCP_blanc_registered.png

The Smart & Secure Communication Protocol (SSCP®) secures the communication of physical and logical access control equipment.


It offers a secure connection between the readers (inspection device) and the management system (concentrator) to guarantee a level of security in line with government requirements. 

The SSCP® protocol offers uniform protection for all your applications by securing interface communication (RS485, USB, TCP-IP, etc.).

It ensures the interoperability of all equipment through conformity certification. What purpose ? Give companies true technological independence for greater freedom!

SPAC® brings the SSCP® protocol to European level to meet the highest security requirements. 

End-to-end security

Conceived and designed to withstand the digital attacks that businesses face, the SSCP® standard is a two-way protocol that creates encrypted and signed communications (AES-128-bit encryption required for​ government facilities, SHA256 signature). The key generation for cryptographic calculations is compliant with the NIST SP800-108 Recommendation. 


The SSCP® protocol is designed to counter man-in-the-middle attacks (hacking or replay attempts between the reader/Inspection System and the system/Concentrator).

Its level of resistance, according to the CSPN certification process set up by the French National Cybersecurity Agency (ANSSI), is level A.VAN.3.

The SSCP standard has security mechanisms that comply with the ANSSI recommendations.

The SSCP® protocol protects:

  • transferred data

  • physical access devices and their software​

  • instruction commands

  • biometric data



The SSCP® protocol is open and offers the best compatibility with your different types of hardware:

  • Access control readers, keypads, touch screens,

  • Biometric readers with fingerprint storage in the badge, the system or the reader,

  • QR Code readers,

  • ATEX readers,

  • Cameras and facial recognition.


The SSCP® protocol is completely independent from the interface, meaning it is not restricted to RS485, like OSDP. It protects the following connections:

  • RS232 and RS485 serial,

  • TCP/IP (with or without POE connector),

  • USB.


The SSCP® protocol can be adapted to any type of communication technology:

  • 13.56 MHz,

  • UHF,

  • Bluetooth®,

  • NFC,

  • multi-frequency solutions,

  • etc.

SSCP® certification

To guarantee the interoperability of the equipment and systems, S.P.A.C.® issues an SSCP® compliance certification in collaboration with a licensed control office.
