Cryptographic computations

WebCryptographic functions, such as encryption/decryption libraries, are common and important tools for applications to enhance confidentiality of the data. However, these functions could be compromised by subtle attacks launched by untrusted operating ... Webkey cryptography for devices such as RFID tags is impossible to achieve. Our results show that outsourced computation makes it possible for such devices to carry out public-key cryptography. Without outsourcing, a device would need O(n) modular multiplications to carry out a modular exponentiation for an n-bit exponent.

WebJul 31, 2024 · This paper surveyed the most popular cryptographic algorithms in privacy-preserving online applications to provide a tutorial-like introduction to researchers in this area. Specifically, this paper focuses on introduction to homomorphic encryption, secret sharing, secure multi-party computation and zero-knowledge proof. Keywords: A cryptosystem that supports arbitrary computation on ciphertexts is known as fully homomorphic encryption (FHE). Such a scheme enables the construction of programs for any desirable functionality, which can be run on encrypted inputs to produce an encryption of the result. Since such a program need never decrypt its inputs, it can be run by an untrusted party without revealing its inputs and internal state. Fully homomorphic cryptosystems have great pra…
