This paper presents a study of successful dictionary attacks against a SSH server and their network-based detection. On the basis of experience in the protection of university network we developed a detection algorithm based on a generic SSH authentication pattern. Thanks to the network-based approach, the detection algorithm is host independent and highly scalable. We deployed a high-interacti...

We performed statistical analysis on the total PTR resource record (RR) based DNS query packet traffic from a university campus network to the top domain DNS server through March 14th, 2009, when the network servers in the campus network were under inbound SSH dictionary attack. The interesting results are obtained, as follows: (1) the network servers, especially those providing SSH services, g...

The Spatial Semantic Hierarchy (SSH) is a multi-level representation of the cognitive map used for navigation in largescale space. We propose a method for learning a portion of this representation, specifically, the representation of views in the causal level of the SSH using self-organizing neural networks (SOMs). We describe the criteria that a good view representation should meet, and why SO...

Secure Shell (SSH) is a multi-channel security protocol running over the Transmission Control Protocol (TCP), which offers channels for several services over a secured connection, such as remote shells and connection forwarding. In this paper we introduce a method for using SSH over the Stream Control Transmission Protocol (SCTP), a transport protocol supporting multi-homing and multi-streaming...

In this paper we perform a review of elliptic curve cryptography (ECC) as it is used in practice today in order to reveal unique mistakes and vulnerabilities that arise in implementations of ECC. We study four popular protocols that make use of this type of public-key cryptography: Bitcoin, secure shell (SSH), transport layer security (TLS), and the Austrian e-ID card. We are pleased to observe...

This note clarifies two important issues related to ocean observations of sea-surface height (SSH) by SWOT. The analysis presented here is intended to supplement the discussion in the SWOT science requirements document, the onboard processing document, and the mission performance and error budget document. The first issue is the question of how the raw SWOT data will be filtered by the onboard ...

Stochastic simulation was used for studying the impacts of sexed semen on genetic progress and reproductive performance of dairy cows. Three strategies were compared: WSS (use unsexed semen in cows and heifers), SSH (use sexed semen in heifers and unsexed semen in cows) and SSCH (use sexed semen in both cows and heifers). Conception rate (CR) of unsexed semen was considered to be 35% and 65% in...

ELSI refers to “ethical, legal, and social issues/implications” of science technology (S&T). The term has been gaining currency in Japan over the last 15 years context its national S&T policy. In this essay, we argue that will become a pivotal concept characterizing relationship between sciences humanities (SSH) country, due particularly first-ever amendment Basic Law scheduled April 2021. And ...
