In this paper, the authors have identified some of the symmetric cryptographic algorithms with the help of which client-side encryption of data can be achieved for enforcing data privacy on the Web. They have also proposed an extended symmetric algorithm using which searchable encryption is possible...
algorithms study of the complexity assumptions used in cryptography TCC is dedicated to providing a premier venue for the dissemination of results within its scope. The conference aims to provide a meeting place for researchers and to be instrumental in shaping the identity of the theoretical ...
Secrecy of the cryptographic algorithm does not provide strength: in fact secret algorithms are often proven quite weak. Strong crypto relies on math, not secrecy, to provide strength. Ciphers that have stood the test of time are public algorithms, such as the Triple Data Encryption Standard (TD...
(i.e., ciphertext). A given algorithm will always transform the same plaintext into the same ciphertext if the same key is used. Algorithms are considered secure if an attacker cannot determine any properties of the plaintext or key, given the ciphertext. An attacker should not be able ...
2.3 Cryptographic Algorithms There are different ways of classifying cryptographic algorithms. One is based on the number of keys used in encryption and decryption. Three types of algorithm, each of which will be briefly elaborated, are given below: • Symmetric cryptography • Asymmetric cryptograp...

Quantum computers are expected to break modern public key cryptography owing to Shor’s algorithm. As a result, these cryptosystems need to be replaced by quantum-resistant algorithms, also known as post-quantum cryptography (PQC) algorithms. The PQC res
Research Papers Injection-Secure Structured and Searchable Symmetric Encryption Ghous Amjad, Seny Kamara and Tarik Moataz We propose the first injection-secure multi-map encryption scheme and use it as a building block to design the first injection-secure searchable symmetric encryption (SSE) scheme. ...
