SCARE: Side Channel Attack on In-Memory Computing for Reverse Engineering

Side-Channel based Reverse Engineering for Microcontrollers

Since side-channel analysis was introduced in the mid-1990s, it has permanently been enhanced and become a reliable method for cryptanalysts to break physical implementations of cryptographic algorithms. Recently, these methods have become of interest to be used for reverse engineering program code running on microcontrollers (e.g., [QS02], [No03]), which are often used in security critical env...

COMPUTING SCIENCE An Acoustic Side Channel Attack on Enigma

Breaking the encrypted message traffic from the German Enigma cipher machine was one of the key allied achievements of World War II, performed at Bletchley Park by a team led by Alan Turing. The work described in this paper was motivated by the historic significance of the Enigma, and the fact that we had the possibility of gaining access to one. This led to the realisation that it would be int...

Countermeasure against Side-Channel Attack in Shared Memory of TrustZone

In this paper we introduced countermeasures against side-channel attacks in the shared memory of TrustZone. We proposed zero-contention cache memory or policy between REE and TEE to prevent from TruSpy attacks in TrustZone. And we suggested that delay time of data path of REE is equal or similar to that of data path of TEE to prevent timing side-channel attacks. Also, we proposed security infor...

Side-Channel Based Reverse Engineering of Secret Algorithms

Two techniques are introduced that enable sidechannel based reverse engineering of secret algorithms. The first is sign-extended differential power analysis (SDPA) while the second technique targets table lookups. The SDPA reveals values that collide with the DPA target value within the circuitry. The interpretation of those values can provide significant amounts of the information about the al...
