Cryptographic computations

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.

Post-Quantum Cryptographic Hardware and Embedded Systems

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… WebAbstract.
