Beware of Pickpockets: A Practical Attack against Blocking Cards. (arXiv:2302.08992v1 [cs.CR])

Today, we rely on contactless smart cards to perform several critical
operations (e.g., payments and accessing buildings). Attacking smart cards can
have severe consequences, such as losing money or leaking sensitive
information. Although the security protections embedded in smart cards have
evolved over the years, those with weak security properties are still commonly
used. Among the different solutions, blocking cards are affordable devices to

generating a noisy jamming …
