A Public Key infrastructure (PKI) binds cryptographic public keys to physical entities
through digital certificates. A PKI includes components that issue digital certificates and
distribute certificate status information. PKI users select one or more certificate issuers as
trust anchors, and establish security services based on certificates that may be validated
using one of their trust anchors.
Abstract: Stuxnet, a sophisticated virus that damaged Iran's nuclear capability, should be an eye openerfor the world. We can choose to learn something very narrow (how to combat the Stuxnet virus) or wecan choose to focus on the larger goal of thwarting the next type of creative cyber attack. Unfortunately,critical industrial infrastructure is not currently designed with security as a key goal, leaving open multipleavenues for an educated and funded attacker to create massive problems. This tutorial outlines somebasic concepts that engineers and product definers should consider to make sure their new projects stayahead of future threats.
Linear Technology offers some of the highest performance RF and signal chain solutions for wireless and cellularinfrastructure. These products support worldwide standards including, LTE, WiMAX, GSM,W-CDMA, TD-SCDMA,CDMA, and CDMA2000. Other wireless systems include broadband microwave data links, secure communications,satellite receivers, broadband wireless access, wireless broadcast systems, RFID readers and cable infrastructure
Abstract: While many questions still surround the creation and deployment of the smart grid, the need for a reliablecommunications infrastructure is indisputable. Developers of the IEEE 1901.2 standard identified difficult channel conditionscharacteristic of low-frequency powerline communications and implemented an orthogonal frequency division multiplexing (OFDM)architecture using advanced modulation and channel-coding techniques. This strategy helped to ensure a robust communicationsnetwork for the smart grid.
In today’s IT environment, Java is a leading technology in the world of enterprise
development. As management demands more from technology, complexity
in infrastructure seems to grow exponentially, leaving many unable to
keep up with the demands of such a fast-paced world. These complexities
can be seen in the over-evolving Java 2 Enterprise Edition (J2EE) specifications.
This unnecessary complexity drove us to discover ways of simplifying
development.
JBoss, one of the leading java Open Source groups, integrates and develops these services for a full J2EE-based implementation. JBoss provides JBossServer, the basic EJB container, and Java Manage Preface 18 Great Events of the Twentieth Centuryment Extension (JMX) infrastructure. It also provides JBossMQ, for JMS messaging, JBossTX, for JTA/JTS transactions, JBossCMP for CMP persistence, JBossSX for JAAS based security, and JBossCX for JCA connectivity. Support for web components, such as servlets and JSP pages, is providedby an abstract integration layer. Implementations of the integration service are provided for third party servlet engines like Tomcat and Jetty. JBoss enables you to mix and match these components through JMX by replacing any component you want with a JMX compliant implementation for the same APIs.
mmread reads virtually any media file. If Windows Media Play can play
it, so should mmread. It uses the Window s DirectX infrastructure to
％ render the media, so other OSs are out of luck.
