Kuro RS

Kuro RS is the programmable interface to all IrDa devices. Kuro learns and remember IrDa signaling from the remote control, and it can control the devices using that signalling by command from computer programming.

Home DLNA

DLNA = Digital Living Network Alliance

DLNA is the alliance networking devices which can work together. If the device had passed to check following the DLNA specifiation, it could show DLNA logo. The sound likes BDA standard in Blu-Ray DVD.

In the easy way to understand DLNA:
DLNA is established to work interoperate between network devices by focus on sharing multi-media in the home network. DLNA must be supported uPnP (Universal Plug and Play). uPnP is a network sharing protocol with zero configuration. However, it have to config in the server side. After the devices is plugged, other connected devices can see files in the server.

SAML

Security Assertion Markup Language (SAML)

SAML is the XML Framework for exchanging security information across the internet. SAML does not provide Identity management, security algorithm.SAML just provide the security exchanging framework.Same as M$ Passport but it can be use with any product.

Advantage: Single Sign On (SSO) , Limitations of Browser Cookies (cannot cross session), Identiy Federation, and Web Services.

SAML has 4 layers: Assertion, Protocol, Binding, and Profile

1. Assertion -> Key with associate to the subject (Authen, Attribute, Authorization)
2. Protocol -> Request and Response pairs for obtaining assertions [Service Provide <--> Identity provider]
3. Binding -> Map SAML message with SOAP
4. Profile -> Set of rules describing how SAML assertions are exchanged, e.g., Browser/POST profile. It combines assertion, protocol and binding for specific scenario (Web SSO Profile)

This is an SAML example.
