Secure Key Storage with Professional Key Management
Secure key storage with professional key management. What was previously only provided by expensive and proprietary hardware security modules (HSM) is now available as open hardware at an unbeatably low price from Germany. Nitrokey HSM reliably protects your cryptographic keys with encrypted backups, two-man rule as access protection and many other security features. With a USB interface, Nitrokey HSM is the ideal solution for certificate infrastructures of any type and size. Applications FEATURES Operating PKI and CA Nitrokey HSM provides secure key generation, Two-Man Rule as Access Protection / storage and management for public key M-of-N Threshold Scheme infrastructures (PKI), certificate authorities In order to gain access to the cryptographic keys, M of N (CA) and other central signing keys.

An Architecture for Cryptography with Smart Cards and NFC Rings on Android
OpenKeychain: An Architecture for Cryptography with Smart Cards and NFC Rings on Android DOMINIK SCHÜRMANN, TU Braunschweig, Germany SERGEJ DECHAND, University of Bonn, Germany LARS WOLF, TU Braunschweig, Germany While many Android apps provide end-to-end encryption, the cryptographic keys are still stored on the device itself and can thus be stolen by exploiting vulnerabilities. External cryptographic hardware solves this issue, but is currently only used for two-factor authentication and not for communication encryption. In this paper, we design, implement, and evaluate an architecture for NFC-based cryptography on Android. Our high-level API provides cryptographic operations without requiring knowledge of public-key cryptography. By developing OpenKeychain, we were able to roll out this architecture for more than 100,000 users. It provides encryption for emails, messaging, and a password manager. We provide a threat model, NFC performance measurements, and discuss their impact on our architecture design. As an alternative form factor to smart cards, we created the prototype of an NFC signet ring. To evaluate the UI components and form factors, a lab study with 40 participants at a large company has been conducted. We measured the time required by the participants to set up the system and reply to encrypted emails. These measurements and a subsequent interview indicate that our NFC-based solutions are more user friendly in comparison to traditional password-protected keys. CCS Concepts: • Security and privacy → Usability in security and privacy; Key management; Hardware-based security protocols; • Human-centered computing → Mobile devices; Additional Key Words and Phrases: NFC, near-field communication, smart card, ring ACM Reference Format: Dominik Schürmann, Sergej Dechand, and Lars Wolf. -

Security and Trust in Open Source Security Tokens
IACR Transactions ISSN XXXX-XXXX, Vol. 0, No. 0, pp. 1–26. DOI:XXXXXXXX Security and Trust in Open Source Security Tokens Marc Schink, Alexander Wagner, Florian Unterstein and Johann Heyszl Fraunhofer Institute for Applied and Integrated Security (AISEC), Germany, [email protected] Abstract. Using passwords for authentication has been proven vulnerable in countless security incidents. Hardware security tokens effectively prevent most password-related security issues and improve security indisputably. However, we would like to highlight that there are new threats from attackers with physical access which need to be discussed. Supply chain adversaries may manipulate devices on a large scale and install backdoors before they even reach end users. In evil maid scenarios, specific devices may even be attacked while already in use. Hence, we thoroughly investigate the security and trustworthiness of seven commercially available open source security tokens, including devices from the two market leaders: SoloKeys and Nitrokey. Unfortunately, we identify and practically verify significant vulnerabilities in all seven examined tokens. Some of them are based on severe, previously undiscovered, vulnerabilities of two major microcontrollers which are used at a large scale in various products. Our findings clearly emphasize the significant threat from supply chain and evil maid scenarios since the attacks are practical and only require moderate attacker efforts. Fortunately, we are able to describe software-based countermeasures as effective improvements to retrofit the examined devices. To improve the security and trustworthiness of future security tokens, we also derive important general design recommendations. Keywords: security token · second factor authentication · FIDO · fault injection attack · side-channel attack · firmware protection 1 Introduction Passwords are the most common authentication mechanism for private as well as profes- sional IT services such as social media, banking or enterprise infrastructure. -
