Revisiting Fully Homomorphic Encryption Schemes [PDF]
arXiv, 2023 Homomorphic encryption is a sophisticated encryption technique that allows computations on encrypted data to be done without the requirement for decryption. This trait makes homomorphic encryption appropriate for safe computation in sensitive data scenarios, such as cloud computing, medical data exchange, and financial transactions.

On the Optimality of Quantum Encryption Schemes
, 2005 It is well known that n bits of entropy are necessary and sufficient to perfectly encrypt n bits (one-time pad). Even if we allow the encryption to be approximate, the amount of entropy needed doesn't asymptotically change.

Design of an Encryption-Decryption Module Oriented for Internet Information Security SOC Design [PDF]
International Journal of Soft Computing And Software Engineering
(JSCSE),Vol.2,No.7, 2012, 2014 In order to protect the security of network data, a high speed chip module for encrypting and decrypting of network data packet is designed. The chip module is oriented for internet information security SOC (System on Chip) design. During the design process, AES (Advanced Encryption Standard) and 3DES (Data Encryption Standard) encryption algorithm are
