Firstly, allow me to recap. A couple of days ago, I reported a presentation at the Chaos Computer Club conference in Berlin which outlined a major problem with the way Certificate Authorities handle message hashing, essentially this attack relied on well-known problems with the MD5 hash algorithm. Problems based on hash collisions, which were previously considered to be theoretical having been discovered in 2004, were now well-lodged within the domain of reality. Have you heard about the news about the reported problem with how Certificate Authorities are handling message hashing? Read on for more information on some security issues with the current Certificate Authorities.. The link for this article located at ITWire is no longer available. .

As web services become more complex and involve interaction between multiple parties, users will require more versatile security.

As web services become more complex and involve interaction between multiple parties, users will require more versatile security. Simple, point-to-point web services can be secured in much the same way as interactive web sessions are secured today, by using Secure Sockets Layer. However, for situations in which security must be preserved throughout a series of cascading web services - operations such as supply chain, transaction brokering, and multi-party fulfilment processes - the key security specification is WS-Security. WS-Security defines the core facilities for protecting the integrity and confidentiality of a message, as well as mechanisms for associating security-related claims with the message. It establishes a security model that brings together formerly incompatible security technologies, such as public key infrastructure, Kerberos, XML Digital Signature and XML Encryption.

Kerberos is an authentication protocol that lets clients and servers reliably verify each other's identity before establishing a network connection. Developed at MIT in the late 1980s, Kerberos takes its name from the three-headed hound in Greek mythology that guards the entrance to Hades. But instead of guarding the underworld, today's Kerberos brings a measure of security to a distributed computer environment, where one computer can access the resources of any other machine on a network.. . ..

Developed at MIT in the late 1980s, Kerberos takes its name from the three-headed hound in Greek mythology that guards the entrance to Hades. But instead of guarding the underworld, today's Kerberos brings a measure of security to a distributed computer environment, where one computer can access the resources of any other machine on a network. Paul Hill, information systems senior programmer at MIT and a member of the Kerberos development team since 1992, outlines the benefits of the Kerberos system. First, it has been subjected to public review for over a decade. Second, version 5 of the protocol-the most current version-was developed within the IETF standards process. Finally, Kerberos provides for secure authentication and message integrity, as well as data confidentiality and mutual authentication between a client and a server.
