  Encryption of Data, Leads to secure Data





In the digital era, security and safety of information delivered digitally are a must for which encryption technology is used.

Data encryption is a security method where information is encoded and can be assist assessed or decrypted by a user with correct encryption key ciphertext it appears scrambled or unreadable to a person without permission so that information remains secure.

Data encryption is useful for protecting sensitive data from negligent parties. An important mechanism is the line of defense cybersecurity is created and encrypts the data. Data encryption software is also known as an encryption cipher. 

Types of Encryption 

  1. Symmetric Encryption – In Symmetric Encryption there is only one key and all communicating parties use the same key for encryption and decryption. A SECRET KEY is used for one to one sharing 

  2. Asymmetric Encryption- Public Key Cryptography uses two linked keys – one private and one public.  Public Key and Private Key is used for encryption and decryption.  One key is used for encrypted and the second key is used for decryption.  The private key is kept private and the Public Key is shared publicly.

Purpose of Data Encryption 

1 Protect confidential data – Encryption is used to protect confidential data  which is stored and transferred digitally. Public Key and Private key is used to encrypt and decrypt the data safely.

2 Protect business for hacking –

In the digital era, Cybercrime is Increasing day by day. Many hackers, hack the data, and information regarding the business plans,  confidential reports which can be misused for their benefits.

3 Regulations – Many regulations requires encrypted data. Many companies handle user data to keep data encrypted.  Example of regulatory and compliance standards that requires encryption includes HIPPA, FCPA, etc

4 Protect from Ransomware

Ransomware is a type of malicious software cybercriminal use to block you from accessing your own data. Although encryption is designed to protect your data, it may also be used as a threat.

Attackers deploy ransomware to attempt to encrypt various devices and servers. They often demand ransom to decrypt back. Ransomware attackers mainly target large organizations and government servers but can also target personal computers as well for their personal and financial gain.

So, encryption is required for secure data and as well we must protect our devices from ransomware by installing and updating the required software.

          The Smallest Computer In The World The Smallest Computer in the World Fits On a Grain of Rice. Researchers at the University of Michigan just created the world's smallest computer (again). After all, it's unclear if the IBM computer even counts as an actual microcomputer. The IBM device lost all its programming and data as soon as it turns off, unlike the Michigan Micro Mote, which retained its programming even when it wasn’t externally powered. “It’s more of a matter of opinion whether they have the minimum functionality required,” said David Blaauw, a professor of electrical and computer engineering at University of Michigan who helped develop the University of Michigan's newest tiny device. If the IBM machine constituted a computer, then University of Michigan would work to gain back their title: their latest micro device measures 0.3mm per side (1/10th the size of IBM’s computer), and is smaller than a grain of rice. The de...

While May is considered a time of new harvest and celebrations for farmers across the country, it also ushers in the dreaded Indian summers, which in turn is symbolized by vacations for children and family trips to the hills for a lot of Indian families.  However, the importance of May runs much deeper than just the basic symbolic inferences to which we as a society often restrict ourselves to. It also has a significant place of honor within religious and spiritual connotations, cultural diversity and societal practices. Here are some of the unique things which make May, the most mystical of all months: Despite a majority of months being named after Greek Gods and even the occasional Roman king, May is named after Maia. She is the Greek Goddess of fertility and this is signified by May being the month of harvest for far...
