WebIn the context of new threats to Public Key Cryptography arising from a growing computational power both in classic and in quantum worlds, we present a new group law defined on a subset of the projective plane F P 2 over an arbitrary field F , which lends itself to applications in Public Key Cryptography and turns out to be more efficient in terms of … 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… how is the views ratings

"WebCryptographic algorithms are most commonly used in smart cards. The chip ensures security by checking cardholder credentials (typically a PIN code) and performing cryptographic operations. Very simple in term of architecture, these cards were initially embedded with the algorithm and an 8-bit core, running at few tens of megahertz. " - Cryptographic computations
