Plenary talk.
SIAM Conference on Applied Algebraic Geometry 2021.
"S-unit attacks."
Abstract:
Within post-quantum cryptography, lattice-based cryptography has attracted attention for its efficiency. Typical proposals for lattice-based encryption systems fit public keys and ciphertexts into only about 1KB, and take very little CPU time. This efficiency relies on using systems built from algebraic number fields. The most common choices are cyclotomic number fields, such as the smallest field containing the complex number ζ=exp(πi/512), a 512th root of −1. | ||||
