We have shown that Walker 256/S mammary carcinoma caused osteoporosis-like changes in young female rats, accompanied by low serum estradiol and hypercalciuria without changes in the serum levels of calcium, phosphorus, and parathyroid hormone-related peptide. In this study, we investigated the cause of bone loss after Walker 256/S inoculation into female 6-week-old Wistar Imamichi rats, focusin...

This paper tlescribes a single-board real-time vision system witli 256 SIMD processors and its performance. The newly developed LSI, IMAP-VISION, integrates 32 &bit; processors, 1 Irocessor on-chip memories and an external memory interface with 160 Ml)yte/s bandwidth on a single chip. With eight IMAP-VISION chips and eight 16 Mhit synclironous DRAMS as external memories, the system has p...

A hash function is near-collision resistant, if it is hard to find two messages with hash values that differ in only a small number of bits. In this study, we use hill climbing methods to evaluate the nearcollision resistance of some of the round SHA-3 candidates. We practi­ cally obtained (i) 184/256-bit near-collision for the 2-round compression function of Blake-32; (ii) 192/256-bit near-col...

In this work, we present a collision attack on 5 out of 8 rounds of the ECHO256 hash function with a complexity of 2 in time and 2 memory. In this work, we further show that the merge inbound phase can still be solved in the case of hash function attacks on ECHO. As correctly observed by Jean et al., the merge inbound phase of previous hash function attacks succeeds only with a probability of 2...

The hash function Kupyna was recently published as the Ukrainian standard DSTU 7564:2014. It is structurally very similar to the SHA-3 finalist Grøstl, but differs in details of the round transformations. Most notably, some of the round constants are added with a modular addition, rather than bitwise xor. This change prevents a straightforward application of some recent attacks, in particular o...

We analyze the Grøstl hash function, which is a 2nd-round candidate of the SHA-3 competition. Using the start-from-the-middle variant of the rebound technique, we show collision attacks on the Grøstl-256 hash function reduced to 5 and 6 out of 10 rounds with time complexities 2 and 2, respectively. Furthermore, we demonstrate semi-free-start collision attacks on the Grøstl-224 and -256 hash fun...

Camellia is a block cipher selected as a standard by ISO/IEC, which has been analyzed by a number of cryptanalysts. In this paper, we propose several 6-round impossible differential paths of Camellia with the FL/FL−1 layer in the middle of them. With the impossible differential and a well-organized precomputational table, impossible differential attacks on 10-round Camellia-192 and 11-round Cam...
