SCinterface VSC

Enables TPM-based virtual smartcards for certificate-based authentication without physical tokens.

SCinterface VSC

Extending smartcard security beyond physical tokens

SCinterface VSC is an extension enabling virtual smartcards using Trusted Platform Module technology. It supports TPM-based, hybrid, and file-based credential storage and integrates with enterprise environments using standard interfaces.

Key capabilities

  • TPM-based key protection, hybrid operation, flexible backend
  • Technical Scope: Virtual credential layer extending middleware
     

Key Features

What sets SCinterface VSC apart

TPM-based smartcard emulation

TPM-based smartcard emulation

SCinterface VSC enables the TPM of a device to be used like a smart card. All smart card functions are emulated.

Hybrid deployment models

Hybrid deployment models

SCinterface VSC supports the smart card file system defined in the ISO/IEC 7816 and PKCS#15 standards. Unlike the Microsoft VSC, all functions are available.

Integration via standard crypto APIs

Integration via standard crypto APIs

SCinterface VSC supports different key formats. The Microsoft VSC, on the other hand, requires a FIPS-186-4-compliant format, which can lead to incompatibilities, especially with older keys.

Benefits

R

Reduced dependency on physical tokens

S

Strong protection of key material

FAQ

Frequently asked questions

SCinterface Virtual Smart Card (VSC) is a software-based smart card solution that replaces physical smart cards by securely storing cryptographic keys in a Trusted Platform Module (TPM) or protected software container. It enables certificate-based authentication, digital signatures, and encryption while maintaining compatibility with enterprise applications and standard smart card interfaces.

SCinterface VSC uses TPM 2.0 hardware security technology to protect private keys against theft and tampering. It supports strong two-factor authentication, advanced cryptographic algorithms, and secure credential management, making it suitable for enterprises, public sector organizations, and regulated industries requiring high security standards.

SCinterface VSC eliminates the need for physical smart cards and card readers while delivering the same security benefits. Organizations benefit from simplified deployment, lower operational costs, easier remote work support, seamless integration with Virtual Desktop Infrastructure (VDI), and a flexible migration path from Microsoft Virtual Smart Card environments.

SCinterface Virtual Smart Card supports Windows 10, Windows 11, major Linux distributions including Ubuntu, Red Hat Enterprise Linux, Debian, Rocky Linux, AlmaLinux, and OpenSUSE, as well as macOS. It integrates with enterprise infrastructures through standard interfaces such as PKCS#11, Microsoft CAPI/CNG, and PC/SC, ensuring broad application compatibility.

Solution

SCinterface VSC

The use of a physical smart card is not always feasible. SCinterface VSC from Eviden Digital Identity makes it possible to use a Trusted Platform Module (TPM) like a smart card. The use without a TPM or in a hybrid mode is equally supported. SCinterface VSC, an extension of the proven smart card middleware SCinterface, offers more than the discontinued Microsoft VSC and allows a smooth migration.
