Implementation of Elliptic Curve Cryptographic Coprocessor over GF(2m) on an FPGA
TLDR
We describe the implementation of an elliptic curve cryptographic (ECC) coprocessor over GF(2m) on an FPGA and also the result of simulations evaluating its LSI implementation. Expand

Variety enhancement of PUF responses using the locations of random outputting RS latches
TLDR
We propose a novel Latch-based PUF structure, which outputs larger variety of responses by utilizing location information of RS latches outputting the random responses. Expand

Address-Bit Differential Power Analysis of Cryptographic Schemes OK-ECDH and OK-ECDSA
TLDR
This paper extends the analysis and shows how the extended address-bit DPA works against scalar exponentiations of elliptic curve based cryptosystems (ECC), even if the algorithm is resistant against the data-based DPA. Expand

Efficient Countermeasures against Power Analysis for Elliptic Curve Cryptosystems
TLDR
This paper proposes two new countermeasures, the Randomized Linearly-transformed Coordinates (RLC) and the Randomizer Initial Point (RIP) against the attacks including the Refined Power Analysis (RPC) by Goubin and the Zero-value Point Analysis (ZPA) by Akishita-Takagi. Expand

The Block Cipher SC2000
TLDR
In this paper, we propose a new symmetric key block cipher SC2000 with 128-bit block length and 128-,192-,256- bit key lengths. Expand

Security evaluation of bistable ring PUFs on FPGAs using differential and linear analysis
TLDR
We propose novel methods of evaluating the difficulty of predicting PUF responses (i.e. PUF outputs), inspired by well-known differential and linear cryptanalysis. Expand

PIATS: A Partially Sanitizable Signature Scheme
TLDR
We propose a new sanitizable signature scheme “PIATS” in which partial information can be sanitized after a signature is signed on the original (unsanitized) document. Expand

A Practical Countermeasure against Address-Bit Differential Power Analysis
TLDR
We propose a practical countermeasure against the address-bit DPA which can be applied to the exponentiation part in RSA or ECC with and without pre-computed table. Expand
