Batch NFS,s in time .. Here .. The circuit’s area-time product (price-performance ratio) is just . per key. For comparison, the best area-time product known for a single key is ...This paper also introduces new “early-abort” heuristics implying that “early-abort ECM” improves the performance of batch NFS by a

Colliding Keys for ,, and non-linear key-schedule we have found a property of the full . (with 256-bit keys) which allows the attacker to find many pairs of keys which generate identical sets of subkeys. Such colliding keys result in identical encryptions. We designed an algorithm that efficiently produces colliding key

Evolve

Faster Binary-Field Multiplication and Faster Binary-Field MACs,thenticator is a standard type of “universal” hash function providing information-theoretic security; what is new is computing this type of hash function at very high speed..At a lower level, this paper shows how to multiply two elements of a field of size . using just . bit operations, and how to m

Security Amplification for the Composition of Block Ciphers: Simpler Proofs and New Results,elds a new block cipher that offers better security against some class of adversaries and/or that resists stronger adversaries than each of its components. One of the most important results in this respect is the so-called “two weak make one strong” theorem, first established up?to logarithmic terms

Improved Differential Cryptanalysis of Round-Reduced Speck,ntains 10 variants, supporting a wide range of block and key sizes. Since the publication of Simon and Speck, several research papers analyzed their security using various cryptanalytic techniques. The best previously published attacks on all the 20 round-reduced ciphers are differential attacks, an

Weak Instances of PLWE,f RLWE, introduced in?[.] and called the PLWE assumption, is known to be as hard as the RLWE assumption for .-power cyclotomic number fields, and for cyclotomic number fields in general with a small cost in terms of error growth. For general number fields, we articulate the relevant properties and p
