WebThe M-Adjoin scheme, first proposed by Khazaei and Rafiee [14, 15], is a symmetric-key primitive that supports the secure join queries for a list of column labels on an encrypted database. WebBlock ciphers are a fundamental primitive of modern cryptography. They are used in a host of symmetric-key constructions, e.g., directly as a pseudorandom permutation to encrypt … Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both the encryption of plaintext and the decryption of ciphertext. The keys may be identical, or there may be a simple transformation to go between the two keys. The keys, in practice, represent a shared … See more Symmetric-key encryption can use either stream ciphers or block ciphers. • Stream ciphers encrypt the digits (typically bytes), or letters (in substitution ciphers) of a message one at a time. An example is See more Examples of popular symmetric-key algorithms include Twofish, Serpent, AES (Rijndael), Camellia, Salsa20, ChaCha20, Blowfish See more Many modern block ciphers are based on a construction proposed by Horst Feistel. Feistel's construction makes it possible to build invertible functions from other functions that are themselves not invertible. See more Symmetric-key algorithms require both the sender and the recipient of a message to have the same secret key. All early cryptographic systems required either the sender or the … See more Symmetric ciphers are commonly used to achieve other cryptographic primitives than just encryption. Encrypting a … See more Symmetric ciphers have historically been susceptible to known-plaintext attacks, chosen-plaintext attacks, differential cryptanalysis and linear cryptanalysis.

WebIn addition, some of these protocols are based on computationally intensive cryptographic primitives, which render them inefficient. To address some of these challenges, a protocol based on masked symmetric key encrypted verification codes is presented in this paper. WebFurthermore, we can construct a ring signature from symmetric key primitives using our compressed one-out-of Nproof (without resorting to the Merkle-tree based accumulator). Comparing with the ring signatures from symmetric key primitives proposed by [51], the size of our ring signature is about 1/3 of [51] when the ring size is less than 24.
