In this paper we explore the technique of “inverse gating” which is a significant improvement over the “round gating” technique introduced in HOST 2016. Round gating worked by generating timing signals to separate glitch propagation from one

Pushed by the pervasive diffusion of devices operated by battery or by the energy harvested, energy has become one of the most important parameter to be optimized for embedded systems. Particularly relevant would be to optimize the energy consumption

In this paper we propose improved Differential Fault Analysis (DFA) on the block cipher Camellia with a 128-bit key. Existing DFAs on Camellia-128 require several faults induced at multiple rounds, at least two of which must be induced at or after th

It has recently been reported that the performance of hyperelliptic curve cryptosystems (HECC) is competitive to that of elliptic curve cryptosystems (ECC). Concerning the security of HECC, the theta divisors play an important role. The scalar multip

Differential power analysis (DPA) might break implementations of elliptic curve cryptosystem (ECC) on memory constraint devices. Goubin proposed a variant of DPA using a point (0, y), which is not randomized in Jacobian coordinates or in an isomorphi

In the past few years, lightweight cryptography has become a popular research discipline with a number of ciphers and hash functions proposed. The designers' focus has been predominantly to minimize the hardware area, while other goals such as low la

In the sine-circle map, the phase-locking structure on the parameter plane (Ω, K )i s known as Arnold’s tongue. The overlapping of two adjacent tongues implies the coexistence of two phase-locked attractors with different rotation numbers. The ph

We propose a new 64-bit blockcipher Piccolo supporting 80 and 128-bit keys. Adopting several novel design and implementation techniques, Piccolo achieves both high security and notably compact implementation in hardware. We show that Piccolo offers a
