Distributed Directory: Security Enhancements

by Tik Ning Cheung, Jeannie Li, Henry Ng
"... The main objective of the project is to add security enhancements to the existing Distributed Directory. Distributed Directory is a decentralized listing of user’s contact information. Each entry is stored in each user’s web server as XML files, known as XML Profiles. The Security enhancements consi ..."

Security Enhanced MPEG Player

by Yongcheng Li, Zhigang Chen, See-mong Tan, Roy H. Campbell - In Proceedings of IEEE First International Workshop on Multimedia Software Development (MMSD'96 , 1996
"... Conventional cryptography deals with the encryption and decryption of traditional textual data. The advent of networked multimedia systems will make continuous media streams, such as real time audio and video, increasingly pervasive in future computing and communications environments. It is thus imp ..."

Modeling Security-Enhanced

by Myla Archer, Elizabeth Leonard, Matteo Pradella , 2003
"... Security-Enhanced (SE) Linux is a modification of Linux initially released by NSA in January 2001 that provides a language for specifying Linux security policies and, as in the Flask architecture, a security server for enforcing policies defined in the language. To determine whether user requests to ..."

End-To-End Arguments In System Design

by Jerome H. Saltzer, David P. Reed, David D. Clark , 1984
"... This paper presents a design principle that helps guide placement of functions among the modules of a distributed computer system. The principle, called the end-to-end argument, suggests that functions placed at low levels of a system may be redundant or of little value when compared with the cost o ..."

of providing them at that low level. Examples discussed in the paper include bit error recovery, security using encryption, duplicate message suppression, recovery from system crashes, and delivery acknowledgement. Low level mechanisms to support these functions are justified only as performance enhancements

Tor: The secondgeneration onion router,”

by Roger Dingledine - in 13th USENIX Security Symposium. Usenix, , 2004
"... Abstract We present Tor, a circuit-based low-latency anonymous communication service. This second-generation Onion Routing system addresses limitations in the original design by adding perfect forward secrecy, congestion control, directory servers, integrity checking, configurable exit policies, an ..."

, and efficiency. We briefly describe our experiences with an international network of more than 30 nodes. We close with a list of open problems in anonymous communication. Overview Onion Routing is a distributed overlay network designed to anonymize TCP-based applications like web browsing, secure shell

Policy analysis for security-enhanced Linux

by Beata Sarna-starosta, Scott D. Stoller - In Proceedings of the 2004 Workshop on Issues in the Theory of Security (WITS , 2004
"... Security-Enhanced Linux (SELinux) extends Linux with a flexible mandatory access control mechanism that enforces security policies expressed in SELinux’s policy language. Determining whether a given policy meets a site’s high-level security goals can be difficult, due to the low-level nature of the ..."

AGAINST ATTACKS FOR SECURITY ENHANCEMENT

by V. Ramach
"... The Hyper Text Transfer Protocol (HTTP) protocol plays a vital role in Web Services Security. Though the HTTPs provide excellent security, they are not flexible enough to allow caches. HTTPi provides high integrity and low security whereas HTTPs provide low integrity and high security. The goal of W ..."

When WS usages are constantly increasing, it is necessary to give proper security as well as flexibility in WS. The requester agent sends

Security Enhancement: Combining Cryptography and

by Dhawal Seth, L. Ramanathan, Abhishek Pandey
"... In today’s world of high technology, it is not safe to share confidential and important data on any network. Intruders are always in wake of it. They hack the data and use it for their benefit. These malicious people try to gain benefit, get attention, or to harm someone. In either case, message sen ..."
