1Physically Secure Cryptographic Computations From Micro to Nano Electronic Devices

Abstract- A recent branch of cryptography focuses on the physical constraints that a real-life cryptographic device must face, and attempts to exploit these constraints to expose the devices se-crets. This gave birth to implementation-specific attacks, which often turned out to be much more efficient than the best known cryptanalytic attacks against the underlying primitive as an idealized object. This talk aims to review some of the physical weaknesses of present technologies and to discuss how future technological scalings may affect these physical security issues. Physical attacks- The classical cryptographic setting only considers abstract computational ad-versaries, modeled as Turing machines. By con
