An (α, β, γ)-LSBS RSA denotes an RSA system with primes sharing α least significant bits, private exponent d with β least significant bits leaked, and public exponent e with bit-length γ. Steinfeld and Zheng showed that LSBS-RSA with small e is inherently resistant to the BDF attack, but LSBS-RSA with large e is more vulnerable than standard RSA. In this paper, we improve the BDF attack on LSBS...

BACKGROUND Respiratory sinus arrhythmia (RSA) is a noninvasive measure of parasympathetic tone that has been related to emotion regulatory capacity. While some previous work indicates that clinically depressed persons exhibit lower levels of RSA than do normal controls, there is nevertheless considerable between-subject variation in RSA among depressed persons. The current study evaluated the s...

LSBS-RSA denotes an RSA system with modulus primes, p and q, sharing a large number of least signi…cant bits. In ISC 2007, Zhao and Qi analyzed the security of short exponent LSBS-RSA. They claimed that short exponent LSBS-RSA is much more vulnerable to the lattice attack than the standard RSA. In this paper, we point out that there exist some errors in the calculation of Zhao & Qi’s attack. Af...

Background Congenital toxoplasmosis is an important cause of spontaneous abortion worldwide. However, there is limited information on detection and genotypic characterization of T. gondii in women with recurrent spontaneous abortion (RSA). The aim of this study is molecular detection and genotypic characterization of T. gondii in formalin-fixed, paraffin-embedded fetoplacental tissues (FFPTs) o...

background: recurrent spontaneous abortion (rsa) and in vitro fertilization (ivf) failure with unknown causes are the controversial issues that are probably related to the immune system. objective: to compare circulating nk cells expressing activation and inhibition surface markers between patients with rsa and ivf failure with those of healthy multiparous and successful ivf control women, resp...

In 1995, Kuwakado, Koyama and Tsuruoka presented a new RSA-type scheme based on singular cubic curves y2 ≡ x3+bx2 (mod N) where N = pq is an RSA modulus. Then, in 2002, Elkamchouchi, Elshenawy and Shaban introduced an extension of the RSA scheme to the field of Gaussian integers using a modulus N = PQ where P and Q are Gaussian primes such that p = |P| and q = |Q| are ordinary primes. Later, in...

We examined whether the combined indices of respiratory sinus arrhythmia at rest (resting RSA) and in response to a sad film (RSA reactivity) predict effective and ineffective responses to reduce sadness (adaptive vs. maladaptive mood repair) in women with histories of juvenile-onset depression (n=74) and no history of major mental disorders (n=75). Structural equation models were used to estim...

This document compares the two published RSA-based hybrid encryption schemes having linear reduction in their security proof: RSA-KEM with DEM1 and RSA-REACT. While the performance of RSA-REACT is worse than the performance of RSA-KEM+DEM1, a complete proof of its security has already been published. This is indeed an advantage, because we show that the security result for RSAKEM+DEM1 has a sma...

Consider the provable security of RSA-OAEP when not instantiated with random oracles. Suppose a security reduction exists to show that finding a plaintext from a RSA-OAEP ciphertext (breaking the basic OW-CPA security) is as hard as the RSA problem. • The reduction can be used in an adaptive chosen ciphertext text (IND-CCA2) attack against RSA-OAEP. • The reduction cannot succeed in the random ...

BACKGROUND In normal pregnancy, predominant type 2 cytokines help maintain pregnancy, and a T-helper (Th)1 type response is associated with unexplained recurrent spontaneous abortion (RSA). However, Th2 and T-cytotoxic (Tc)2 cells have not been localized at the implantation site in RSA. METHODS Twenty-one cases with RSA were classified into RSA with normal chromosomal content (RSA-N, n = 10) ...
