Abstract

It is essential to secure the implementation of cryptosystems in embedded devices against side-channel attacks. Namely, in order to resist differential (DPA) attacks, randomization techniques should be employed to decorrelate the data processed by the device from secret key parts resulting in the value of this data. This peak appears only if the attacker’s guess of a bit or a digit of the secret key is correct. The attacker’s goal is to retrieve partial or full information about a long-term key that is employed in several ECSM executions. In this paper we proposed secret key to calculate the number of bits or digits processed in an n-bit prime integer for SPA attacks in the execution of elliptic curve scalar multiplication executions.
