Book ChapterDOI
Fixed-point arithmetic in SHE schemes
TL;DR: The purpose of this paper is to investigate fixed-point arithmetic in ring-based Somewhat Homomorphic Encryption schemes, and achieves a way of producing lower bounds on the plaintext modulus p and the degree of the ring d needed to support complex homomorphic operations.
Book ChapterDOI
On the performance of hyperelliptic cryptosystems
TL;DR: It is concluded that hyperelliptic curves offer no performance advantage over elliptic curves, and the implementation of the group law on such curves and how to generate suitable curves for use in cryptography is covered.
Book ChapterDOI
An Analysis of Goubin’s Refined Power Analysis Attack
TL;DR: This paper examines Goubin’s attack in more detail and completely discount its effectiveness when the attacker chooses a point of finite order, and proposes a defence based on using isogenies of small degree.
Book ChapterDOI
Secure outsourced computation
Jake Loftus,Nigel P. Smart +1 more
TL;DR: It is shown that if one provides the set of computation engines with a small piece of isolated trusted hardware one can outsource any computation in a manner which requires less security constraints on the underlying communication model and at greater computational/communication efficiency than full multi-party computation.
Journal ArticleDOI
Public key signatures in the multi-user setting
TL;DR: The security of public key signature schemes in a "multi-user" setting is addressed and the concrete security of this general reduction for certain specific discrete logarithm based signature algorithms such as that of Schnorr is improved.
