ABSTRACT
The latest innovation technology in computing devices has given a rise of compact, speedy and economical products which also embeds cryptography hardware on-chip. This device generally holds secret key and confidential information, more attention has been given to attacks on hardware which guards such secure information. The attacker may leak secret information from symmetric crypto-hardware (AES, DES etc.) using side-channel analysis, fault injection or exploiting existing test infrastructure. This paper examines various DFT based attack implementation method applied to cryptographic hardware. The paper contains an extensive analysis of attacks based on various parameters. The countermeasures are classified and analyzed in details.
KEYWORDS
