How Is Java Knitting Rapidly Into The Embedded Space?

The "Java" family of technologies has always been considered on the apex of all software technologies. Owing to its salient features, such as flexibility, open source nature, compatibility, ease of use, adaptability and many more, Java has always been interweaving itself into multiple latest happenings, frameworks and architectures. Java Application Development has been pervasive in the embedded space at a very rapid rate. Java has been chosen as the apt language for embedded devices owing to the continuously increasing complexities in the software arena.

This embedded technology is woven into devices and systems, ranging from chips (on credit cards or ID cards) to bigger server class instruments to home driven equipments and is tightly coupled with the device. It brings about a real time experience for the user. Today, there are many daily usage devices based on this technology and Java is spreading its embedded wings into devices like SIM cards, printers, bank machinery, mobile handsets, TV, AC to name a few.

Java Embedded is usually not available for direct download or installation to users. It is based on an integration mechanism by the electrical / electronic manufacturers, directly on the device.

Why is Java Embedded getting so popular and in-demand?
    • Since it is highly functional, trustworthy, convenient and secure, Java Embedded tends to get attracted to solution providers at a breath taking pace.
    • It is bound to improve product quality.
    • Presence of standardized class libraries is bound to increase productivity and decrease rework.

An Overview of Cryptography

Cryptography is the algorithm or process of encryption of plain data to cipher data and decryption of cipher data to plain data. A secret key(s) is used in this process and the length and type of keys are varies depending on the algorithm we choose.

Everyone wants their message is transfer over a network securely. Encryption also needs as it is required by organization or country law. There are many organizations and country having law that people may not share/upload data on FTP or cloud without encryption.

Basically, there are two type of cryptography is being used: Symmetric cryptography and Asymmetric cryptography.

Symmetric cryptography

It is one of the ways to encrypt the plain text and decrypt the cipher text via common/secret key. In this algorithm common/secret key is shared between all concern parties, so they can encrypt and decrypt the message with same keys.

Advantage of this approach is that implementation is simplest and faster than the asymmetric cryptography. However, main drawback is that we have to share the key securely between concern parties.

There are various symmetric algorithm available and it can mostly be classified in two categories : Stream and block cipher.

DES (Data Encryption Standard), Blowfish, RC4, AES (Advanced Encryption Standard) are the commonly and widely used symmetric algorithm.

Asymmetric cryptography

Asymmetric cryptography/encryption, also called as public key cryptography/encryption, is another way of encryption and using the key pair (public-key and private-key) instead of only one key in case of symmetric cryptography.

Here, public-key is used to encrypt the message and private-key is used to decrypt the message. Public-key may be shared to the users to encrypt the message. However, only authorized user who have corresponding private-key can decrypt the message. No one can decrypt the message if they have only public-key.

Advantage of the public-key is it is more secure than symmetric cryptography. However, it is much slower than the symmetric algorithm.

RSA (Rivest Shamir Adleman), ECC (Elliptic Curve Cryptographi) and Digital Signature Algorithm (DSA) are the widely used asymmetric encryption algorithm where public-private key pair is being used.

Public cryptography generally used 1024 bits long key. However, now a days key with 1024 bits length is not considering secure. However, increasing key length slow down the encryption/decryption process. So there is a trade off to choose the correct length of the key pair. Currently, 2048 bits long key is widely accepted and used.

Digital Signature Algorithm, is used to verify the sender. Here, sender and receiver respective keys to sign and verify the message. Sender digitally sign the message using his private-key. To make sure that the content is received of the correct sender, receiver verify the signature using corresponding public-key of the sender.

In Java programming, a common type of search space is described by a Graph. Typically, a graph is a set of nodes and links. The nodes contain the following data:

> A name and/or other data
> Zero or more links to some other nodes
> A position in space

The links which fall in between the nodes are often referred to as edges in Java programming. The short algorithms and programs which are used in finding paths in graph are very similar to finding paths in a 2D maze. The primary difference here is the operators that allow the Java programmers to move and hence execute the code from one node to another.

At SPEC INDIA, we are well-equipped with a trained team of around 60+ Java programming professionals with an average experience of 2.8 years per engineer.  Feel free to post us your requirement at our email id lead@spec-india.com and our Business Development Executive of the concerned department will get back to you within 24-48 hours.

Java Programming: Creating & Implementing ATG Droplets

In Java programming, creation of your own ATG droplets is an easy task. Servicing a default open parameter (oparam) in an ATG droplet is again surprisingly extremely easy.

ATG has these things called “droplets” that you use from within your “dsp” tag library. You can –nay– you SHOULD make your own droplets. You should have as little Java code in your JSP pages as humanly possible.

To do this, Java programmers need to take the following steps:
1. Create a .java file
2. Extend ‘DynamoServlet’
3. Create the .properties file
4. Define your properties
5. Implement the droplet

JQuery V/s. JavaScript

JQuery and JavaScript; both are the structured query languages used vastly by the Java developers. We are talking this opportunity to compare both these and thus try to figure out like which best fits at what time.

Firstly – JQuery is a JavaScript library and it is easy to install by importing a script inside a Web page. It provides a lightweight library consisting of many advanced cross-browser functions to the standard language. With this, the JQuery contains a very dynamic community for more advanced components.

Now, JavaScript usage might cause some issues related to browser compatibility. JavaScript is basically a low-level programming language. It does not provide anything regarding the animations, as well as page manipulation and decoration functions. Thus, the web programmers might be somewhat less reluctant towards the JavaScript applications difficult to code, and thus resulting in high maintenance costs.
