ONLINE DATA SHARING SECURITY CHIP

  • Department of electronics and communication engineering of Indian Institute of information Technology (IIIT) Alahabad, has designed a random number chip, which will be used for data security and encryption.
  • The chip will be useful in automatically and effectively encrypting and decrypting data being transmitted through e- ways using devices like laptops, mobile phones, desktop on tablets, there by, preventing any unauthorised person from being able to intrude upon it.
  •  This indigenously developed chip is more advanced than ones being used in most smart devices today, will also be cheaper than imported ones being used.
  • The chip prevents being hacked and data theft.
    What are encryption and decryption?

In simple terms, to obtain secure communication, the data ( original information is often called plain text) is converted to an alternative form called encrypted data ( encoded information, often called cipher text) and sent and later decryption. These coding of original data is called encryption and decoding it further is called decryption. This is done to secure privacy of  sensitive information.

  • To design such a system and to carryout encryption and decryption , random numbers play an important role for such design''
What are random number?

 Random numbers are critical parts of computer and internet security and inappropriate random number may altogether weaken the security system that are principally strong. A random generator  is a computational or physical device designed to generate a sequence of numbers or symbols that cannot be predicted or lacks a pattern. The quality of a random number as a measure of how truly random the number is.

What is Random number generator?

random number generator is a key primitive in many application including monte-carlo simulation, statistical sampling, truly randomised design, gambling, gaming and other areas like crypto-graphic algorithms and applications where producing unpredictable results are desirable.

Normally, there are two type of random generators namely '' Pseudo Random number generator (PRNG) and ' True Random Number generator' (TRNG).

PRNG : Pseudo Random number generators employ certain algorithms to obtain a random stream of bits.

  • The output of these Random number generator (RNG) can therefore be predicted using a key, known as seed, which raises the need for TRNG.
  • RNG that use a physical source of random are called true random number generator (TRNG), a task that this chip and if software perform.

 ALGAL BLOOM   Keywords :  Alga (singular subject/ noun) Algae ( plural subject/noun) Mycrocystis (alga) microcystin( toxin / poison) DO: oxygen dissolved in water, generally 4mg/l required to sustain the life in water.  Eutrophication   (Neutrients enrichment in water bodies ) : The excess of fixed nitrogen builds up in streams and lakes where provides extra food for microorganisms and causes a bloom in the population of algae. The algae population eat up oxygen and eventually, brings the waterbody on the brinks of death. Algal bloom in river  Algal bloom( algal pollution) is a condition of excessive sudden  population growth of algae on the surface of water bodies in mat form because of sudden increase of nutrients like nitrogen and phosphorus that leads food chain disturbance in water bodies. Actually microscopic plants( algae) are unicellular, aquatic, roots, and leaves. Algae are required nutrients for growth by the process of photosynthesis; ...

Sati

  Topic.        Indian society .        Modern history   Issues related to women during colonial period  Prelims  Mains GS1  Sati   It was a orthodox evil practice to burn widow alive on her husband's pyre without her will. This practice was largely followed by the higher classes of the society.  It was William bentinck who made it a crime against humanity in 1829 and strongly supported by  Rajaram Mohan Ray. It was the main achievement of British government in India to to modernise the societies of India  Government of India passed an act in 1856 to enable widow remarriage  and  Pandit Iswar Chandra Vidya Sagar had requested for making law regarding widow remarriage.  Government of India tried to practice of killing women infanticide and dowry system.

Topic.                Health diseases                                                             Prelims   Zika virus Zika virus disease is caused by a virus transmitted primarily by Aedes Mosquitoes and Albopictus Mosquitoes, which bite during the day.  Zika is Mosquitoes borne virus that spread through the bite of an infected  Aedes species of Mosquitoes named Aedes Aegypti and Albopictus Mosquitoes by a virus called Zika.  Zika virus is caused by the Same Mosquito that causes Dengue. According to the WHO the Aedes Mosquitoes usually bite during the day, peaking during early morning and late afternoon or evening.  What is mean by Mosquitoes borne virus? Borne means carried by or moved by a particular thing such as airborne diseases in which diseases is carried by one pla...
