WebMar 18, 2015 · We introduce and instantiate a new cryptographic primitive, called non-interactive distributed encryption, that allows a receiver to decrypt a ciphertext only if a minimum number of different senders encrypt the same plaintext. The new functionality can be seen as the dual of the functionality provided by threshold cryptosystems.

WebFeb 1, 2024 · 3. Digital signatures. Besides the hash function, the digital signature is another inevitable cryptographic primitive in blockchains. The concept of the digital signature was put forward by Diffie and Hellman in 1976 when they opened the gate of public key cryptography ( Diffie and Hellman, 1976 ). WebJun 7, 2024 · This requires the PUF to have access to a large source of entropy, either in the form of IC features from which random information is extracted, or in an artificial form using a cryptographic primitive, such as a secure hash function. Either mechanism makes the PUF resilient to machine learning attacks. how are knowing and accepting differentWebIt's a really broad term, and might cover anything from ancient substitution ciphers like the Caesar cipher to modern-day public-key ciphers like RSA.
