Innovative Countermeasures to Defeat Cyber Attacks Against Blockchain Wallets: A Crypto Terminal Use Case. (arXiv:2303.17206v1 [cs.CR])

Blockchain transactions are signed by private keys. Secure key storage and
tamper-proof computers are essential requirements for deploying a trusted
infrastructure. In this paper, we identify some threats against blockchain
wallets and propose a set of physical and logical countermeasures to thwart
them. We present the crypto terminal device, operating with a removable secure
element, built on open software and hardware architectures, capable of
detecting a cloned device or corrupted software. These technologies are based
on tamper-resistant computing (javacard), smart …
