The additional information (side effects) in Elliptic Curve Cryptography (ECC) hardware can be used to attack cryptographic systems. Additional information related to time, power consumption and electromagnetic radiation. Side channel attacks have been done with SPA (Simple Power Analysis), DPA (Differential Power Analysis), SEMA (Simple Electromagnetic Analysis) and DEMA (Differential Electromagnetic Analysis). Some scalar multiplication algorithm can be used to countermeasure SPA attack on elliptic curve cryptography. In this study, conducted experiments side-channel attacks ECC hardware implementations use binary algorithms by observing power consumption of ECC processor on FPGA. Experimental of side-channel attack is conducted to guess the secret key for data encryption and decryption by looking at the physical differences on hardware side effects. In this study, side-channel attack experimental is successful 100% get the key by analyzing of power consumption ECC processor.
