Recently, several research groups in cryptography have presented new elliptic curve
models based on Edwards curves. These new curves were selected for their good
performance and security perspectives. Cryptosystems based on elliptic curves in
embedded devices can be vulnerable to side-channel attacks (SCA), such as simple power
analysis (SPA) or differential power analysis. In this paper, we analyze the existence of
special points—whose use in SCA is known as same value analysis (SVA)—in the case of …

whose use in SCA is known as Same Value Analysis (SVA), for Edwards curves. These …
