Online Template Attack on ECDSA: [chapter]

Niels Roelofs, Niels Samwel, Lejla Batina, Joan Daemen
2020 Lecture Notes in Computer Science  
We retrieve the ephemeral private key from the power trace of a single scalar multiplication in an ECDSA signature generation and from that the signing private key using an online template attack.  ...  The innovation is that we generate the profiling traces using ECDSA signature verification on the same device.  ...  The first one is on portability and the other one is the work on online template attacks.  ...
