Negative interest rates, excess reserves and tiering of the ECB: How heavily are banks burdened? by Jens Klose

“…Banks are increasingly facing problems investing their deposits without taking great risks and avoiding nominal depreciation. This article shows, however, that the deposit rate has never been the effective lower bound for deposits at the ECB and, moreover, the decision in September 2019 to introduce the tiering programme increased the average deposit rate rather than decreased it as one would have supposed. …”

ID-based on-line/off-line threshold signature scheme without bilinear pairing by Xiao-dong YANG, Chun-mei LI, Ting XU, Cai-fen WANG

“…Based on the distributed key generation (DKG) protocol and verifiable secret sharing (VSS) protocol,an identity-based on-line/off-line threshold signature scheme was proposed in order to eliminate the cost of the certificate management in the public key cryptosystem and improve the performance of on-line/off-line threshold signature schemes.This scheme was proven to be robust and unforgeable under the discrete logarithm assumption.Analysis results show that the proposed scheme eliminates the problem of certificate management and pairing operation,and it greatly reduces computation cost of off-line threshold signature generation algorithm and signature verification algorithm.The new scheme is more efficient than the available on-line/off-line threshold signature schemes.…”

Fault-injection attack on countermeasure algorithms of RSA-CRT cryptosystem by Fanyu KONG, Yong QIAO, Pengtao LIU, Xiaodong LIU, Dashui ZHOU

“…As a widely-applied public-key cryptosystem in TLS,SSL and IPSec protocols,the security of RSA cryptosystem is of great importance.At FDTC 2014,Rauzy and Guilley proposed several improved countermeasure algorithms of RSA implementation based on Chinese remainder theorem,which were used to defeat fault-injection attacks.New fault-injection attacks on two of their countermeasure algorithms are proposed.During the RSA computation process,a permanent fault is injected and then a faulty RSA signature result is induced.The RSA private key can be obtained by using the faulty RSA signature and the correct result.Therefore,Rauzy and Guilley’s two countermeasure algorithms cannot resist our fault-injection attack.…”
