Security Products Overview

Swissbit relies on over 20 years of experience in the development of flash memory solutions for the most demanding markets. With its secure storage solutions, Swissbit addresses the increasing security requirements demanded by industrial, government, defense, medical, telecommunications, machine-to-machine communication and finance industry segments.



The products offer tangible hardware security in a plug and play approach. For various markets, Swissbit offers solutions for a broad set of security use cases. The flash memory can be used by any host to store data on the cards at high speed. Additionally security functions of the card can be activated to protect any data and the secure element can be used for authentication applications.


Security in the shape of a SD Memory Card

Valuable data such as sensitive files, emails, photos, OS images, FW updates, log files and audit trails can be protected by encryption, authentication and access protection, or made resistant to tampering by digital signature. Voice and video calls as well as data streams for M2M communication (IoT) can be protected by the card in high speed. The best fitting product can be chosen depending on the use case.


Our security product series provides a smart card chip or a security extension to the Swissbit durabit™ firmware or combination of both. The Swissbit Security Interface empowers solution providers to build applications on various platforms. An SDK is available to develop applications on Windows™ and Linux™ PC platforms and on mobile phones and tablets like Android™ and BlackBerry™.

The Standard Edition SE fits best into authentication and PKI (Public Key Infrastructure) use cases. The card is supported by leading middleware vendors in mobile, desktop, and tablet use cases to ensure a seamless design-in into existing security infrastructures.




The Voice Edition PS-100u VE provides Elliptic Curve Cryptography. The enormous advantage of computation and security combined with small certificate sizes makes a VE card ideal for online key and certificate exchange.



Solution providers choose the VE card to build secure mobile voice solutions. Typically the users (caller and person called) only need to enter their PIN into their mobile device and the security chip performs end-to-end encryption on their behalf. All encryption keys for authentication and key agreements remain highly protected in the card at all times. Only AES key stream segments suitable for voice stream encryption are passed to the mobile host application. The VE card extends the features of the SE card.




The DP and PE cards provide flash memory encryption and access protection, secure logging, and flexible CD-ROM storage. The PE cards offer asymmetric and symmetric cryptography like the VE cards by the embedded smart card chip, whereas the DP cards offer symmetric encryption without smart card chip by the durabit™ FW.




FE cards provide a secure element according FIPS 140-2 certification. US governmental organizations and enterprises that need to follow the FIPS 140-2 security standard benefit from smart integration into a storage form factor.






EDN has nominated Swissbit’s security product PS-100u mircoSD memory card as one of the “100 Hot Products of 2015.”
