![]() ![]() Regulatory curbs may slow Blockchain innovations in India “The (Indian) regulatory ecosystem is.not (focusing) on decentralised systems like smart contracts, so innovation will not happen at the same pace as in those countries who do allow for experimentation in such aspects of the technology,” said Nitin Sharma, founder of Incrypt Blockchain.Dhiway offers blockchain tech for data verification This is to help companies and individuals avoid the hassle of establishing their personal identities, credentials or data many times over.IIT Guwahati research team working towards protecting data from cyber attacks The team has also designed encryption architectures that can be used to protect sensitive health data that is transmitted through the internet.Internet and privacy activists have raised concerns about commercial or law enforcement use of sensitive personal data collected by the app. Eight organizations and 145 individuals write to govt on concerns on Aarogya Setu app The Aarogya Setu mobile app has been mired in controversy was introduced by the government as a contact tracing app in April.Hash functions are also used by many operating systems to encrypt passwords. A fixed-length hash value is computed as per the plain text that makes it impossible for the contents of the plain text to be recovered. Hash Functions: No key is used in this algorithm. The public key is used for encryption and for decryption private key is used. Public key may be freely distributed, while its paired private key, remains a secret. In Public-Key Cryptography two related keys (public and private key) are used. Public-Key Cryptography: This is the most revolutionary concept in the last 300-400 years. On the other side the receiver applies the same key to decrypt the message and recover the plain text. The sender uses this key to encrypt plaintext and send the cipher text to the receiver. Symmetric-key Cryptography: Both the sender and receiver share a single key. ![]() Three types of cryptographic techniques used in general. Non-repudiation - Sender cannot deny his/her intentions in the transmission of the information at a later stageĪuthentication - Sender and receiver can confirm eachĬryptography is used in many applications like banking transactions cards, computer passwords, and e- commerce transactions. Integrity - Information cannot be altered. Cryptography not only protects data from theft or alteration, but can also be used for user authentication.ĭescription: Earlier cryptography was effectively synonymous with encryption but nowadays cryptography is mainly based on mathematical theory and computer science practice.Ĭonfidentiality - Information cannot be understood by anyone ![]() It is a method of storing and transmitting data in a particular form so that only those for whom it is intended can read and process it. In your version of the sentence, vice versa does not make sense as a synonym for "conversely.Definition: Cryptography is associated with the process of converting ordinary plain text into unintelligible text and vice-versa. However, the preposition has dropped out of use in the 20th century except in military contexts, so there's a high risk of being misunderstood.įurthermore, vice does not serve as an abbreviation of the adverb vice versa. So you could technically say "I will use this product, vice the other one" to mean you'll use this product instead of the other one. In both forms, the preposition is preceded by a comma and takes a (usually personal) object. 111 It was.soon afterwards reorganized, with Mr. Here's another example from the Oxford English Dictionary:ġ886 C. : in the place of / "I will preside, vice the absent chairman" ![]() It is similar to the prefix vice represented in titles like vice president and vice principal, and means ( Merriam-Webster): There is a preposition vice, more common in the 18th and 19th century. ![]()
