WebDo not use a technique called ‘blinding’, which is used by default in order to prevent leaking of secret information. Blinding is only implemented by RSA, but it might be implemented by other algorithms in the future as well, when necessary. param For ECC key generation also return the domain parameters. WebThe most popular countermeasures against DPA in El- liptic Curve Cryptography (ECC) have been proposed by Coron [4] and Clavier and Joye [5], namely scalar split- ting, scalar randomization, and point blinding. All of these blinding countermeasures either randomize the secret scalar or the base point of the curve.
