Identity Registration Protocol

Identity Registration Protocol is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Identity Registration Protocol rather than just read about it. In short: The Internet Assigned Numbers Authority (IANA) officially assigned TCP port 4604 to the Identity Registration Protocol (IRP) created by Sixscape Communications, Pte. Ltd.

Key takeaways

Identity Registration Protocol belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Identity Registration Protocol to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Identity Registration Protocol from memory before moving on to harder problems.

Reference excerpt

The Internet Assigned Numbers Authority (IANA) officially assigned TCP port 4604 to the Identity Registration Protocol (IRP) created by Sixscape Communications, Pte. Ltd. The assignment was issued by IANA on 17 March 2014, and is listed in the official IANA resource registry. There are a very limited number of port numbers, which are assigned by IANA for protocols recognized as viable, complying with current protocol design standards, and not already covered by existing Internet standards. For example, port 25 was assigned to the SMTP email protocol many years ago. This establishes a standard and eliminates conflicts with other protocols. The technical review of IRP was performed by Lars Eggert, the distinguished chair of the Internet Research Task Force. IRP was created by Lawrence E. Hughes, co-founder and CTO of Sixscape Communications, to allow applications to register their name, email address, UserID, their current IPv6 address and other information with the company's Domain Identity Registry server. IRP also supports all functions of a Public Key Infrastructure and an authenticated Address Registry. Sixscape's Domain Identity Registry server issues and manages X.509 client digital certificates for authentication and secure messaging. The Address Registry feature enables a new connectivity paradigm, called End2End Direct, in which user applications can connect directly to each other rather than via intermediary servers as is common with Client/Server architecture applications common on the older IPv4 Internet. IRP is a streaming network protocol (TCP-based, connection-oriented). It is a Client/Server design with clearly defined server and client roles and implementations. It is secured with TLS v1.2 using the latest, strongest ciphersuites (e.g. Diffie Hellman Ephemeral for key exchange, AES256 for symmetric encryption and SHA2/384 for message digest). It does server to client authentication using an X.509 Server certificate, similar to web or email servers. It normally does client to server authentication with X.509 client certificates (usually obtained via IRP), with fallback to Username/Password Authentication (UPA) if needed. UPA can be disabled on a per-user basis. IRP protocol messages are valid XML documents.

Worked examples

Example 1 — a first encounter with Identity Registration Protocol

Start with the simplest possible case. Write down what Identity Registration Protocol claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Identity Registration Protocol before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Identity Registration Protocol ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Identity Registration Protocol

In research: Identity Registration Protocol appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Identity Registration Protocol in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Identity Registration Protocol is common in secondary-school and first-year university syllabi. It links to neighbouring topics Data transmission, Internet stubs, Network protocols, so understanding it makes those chapters shorter.
In everyday life: Look for Identity Registration Protocol outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Identity Registration Protocol in simple terms?

The Internet Assigned Numbers Authority (IANA) officially assigned TCP port 4604 to the Identity Registration Protocol (IRP) created by Sixscape Communications, Pte. Ltd.

Why does Identity Registration Protocol matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Identity Registration Protocol?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on Identity Registration Protocol.
