Emerging Cryptography

Question 1

SHE somewhat homomorphic encryption

Answer 1

Supports limited operations, to a certain complexity, but these operations can only be performed a set of numer of times

Question 2

PHE partially homomorphic encryption

Answer 2

One operation can be performed on unlimited number of times on the ciphertext

Question 3

Quantum encryption

Answer 3

Applies principles of quantum mathematics to encrypt messages.this encryption process invokes “no changes theory”what means that cannot be interrupted

Question 4

Homomorphic encryption

Answer 4

Allows for encrypted data to be processed. Uses complex mathematical operations to allow a variety of operations on encrypted data. There are 2 types of homomorphic encryption:
SHE - somewhat homomorphic encryption
PHE partially homomorphic encryption - fully homomorphic encryption still in development
This is method of encryption that allows data to remain encrypted while it’s being processed. This encryption produces encrypted results

Question 5

Post-quantum encryption

Answer 5

This is encryption which must be created to develop cryptographic systems that are secure against both quantum and classical computers and can interoperate which existing communications protocols and can interpolate with existing communications protocols and networks. Quantum computers will be able to break many public-key crypto systems currently in use.

Question 6

Blockchain

Answer 6

Decentralized public ledger. Blocks are linked using cryptography. Each block contain cryptographic hash of the previous block, a timestamp, and transaction data. Digital signatures are used for authenticity. Public key (asymmetric) encryption serves as the basis for blockchain wallets and transactions.
