CVE-2019-15809

Smart cards from the Athena SCS manufacturer, based on the Atmel Toolbox 00.03.11.05 and the AT90SC chip, contain a timing side channel in ECDSA signature generation. This allows a local attacker, able to measure the duration of hundreds to thousands of signing operations, to compute the private...

CVE-2019-15809

CVE-2019-15809 describes a timing side-channel in ECDSA signature generation on Athena SCS smart cards (AT90SC) using Atmel Toolbox 00.03.11.05. The toolbox includes two ECDSA implementations, fast and secure; affected cards selected the fast variant, leaking the bit-length of the nonce via timin...
