SSCP Standard

logo SSCP_blanc_registered.png

The Secure & Smart Communication Protocol (SSCP) protects the communications of physical and digital access control equipment.


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

The SSCP protocol provides uniform protection for all your applications by protecting interface communications (RS485, USB, TCP/IP, etc.).

It guarantees the interoperability of all equipment through compliance certification. Why? To provide businesses with genuine technological independence, giving them greater freedom!

SPAC is elevating the SSCP protocol to European level in order to meet the most stringent 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, SPAC issues an SSCP compliance certification in collaboration with a licensed control office.
