Digital transactions require very well secured and at the same time user-friendly solutions. This is especially true for blockchain applications, where user identification is one of the critical security aspects. Infineon now offers FinTechs and Blockchain designers the ability to integrate hardware-based security into their systems with their Blockchain Security 2Go Starterkit.

Storing blockchain user data on a computer or mobile phone is convenient, but can be risky, warns Infineon. Attackers could identify and read sensitive information such as the user’s confidential private key. This can even be done remotely through software attacks, giving the attacker full control over this blockchain user and its assets, whether crypto money, identity or contracts. Similarly, if the user ID is lost, access to the values is lost, since the logon information is usually not stored centrally and cannot be restored. There is an urgent need to increase user ID security by integrating a token with a security chip that protects against both software attacks and physical attacks.

To protect blockchain applications against unauthorized access and hacker attacks, Infineon has now developed a starter kit. The kit contains five NFC smart cards with Infineon security chips that provide crypto functionality for various blockchain applications. In addition, an open source Android app for Ethereum including smart contract examples is provided. The NFC Smartcards help system designers of blockchains to quickly and easily develop first prototypes for blockchain applications. With security tokens – whether card, dongle or integrated chip solution – users can generate their individual public and private keys, authenticate themselves with their PIN and sign their data and digital transactions. All user data can be stored in the security chip. They are thus protected against attacks from the network on software and microarchitecture, and in particular against physical attacks on the chip itself, for example in the event of theft or loss of the security token.

The Blockchain Security 2Go Starterkit will be available in the first quarter of 2019.
