Recursive n-gram hashing is pairwise independent, at best [PDF]

, 2010
Many applications use sequences of n consecutive symbols (n-grams). Hashing these n-grams can be a performance bottleneck. For more speed, recursive hash families compute hash values by updating previous values.

Finding succinct ordered minimal perfect hash functions [PDF]

Information Processing Letters, 1994
Abstract An ordered minimal perfect hash table is one in which no collisions occur among a predefined set of keys, no space is unused and the data are placed in the table in order. A new method for creating ordered minimal perfect hash functions is presented.

Efficient Gauss Elimination for Near-Quadratic Matrices with One Short Random Block per Row, with Applications [PDF]

, 2019
In this paper we identify a new class of sparse near-quadratic random Boolean matrices that have full row rank over F_2 = {0,1} with high probability and can be transformed into echelon form in almost linear time by a simple version of Gauss elimination.

Hardware Security for Edge Computing Via CMOS‐Compatible Multi‐Level Flash Memory with Hash‐Based Key Generation

Advanced Electronic Materials, EarlyView.
A CMOS‐compatible flash memory structure with multi‐level programming produces reliable and reproducible physically unclonable functions (PUFs) for secure IoT applications. Device‐specific variations in flat‐band voltage enable scalable key generation without standby power.

Quantum Key Distribution with Blind Polarization Bases [PDF]

, 2005
We propose a new quantum key distribution scheme that uses the blind polarization basis. In our scheme the sender and the receiver share key information by exchanging qubits with arbitrary polarization angles without basis reconciliation.

A Risk Manager for Intrusion Tolerant Systems: Enhancing HAL 9000 With New Scoring and Data Sources

Software: Practice and Experience, EarlyView.
ABSTRACT Background Intrusion Tolerant Systems (ITS) aim to maintain system security despite adversarial presence by limiting the impact of successful attacks. Current ITS risk managers rely heavily on public databases like NVD and Exploit DB, which suffer from long delays in vulnerability evaluation, reducing system responsiveness. Objective This work

Perfect Hash Function Generation on the GPU with RecSplit

, 2022
Minimale perfekte Hashfunktionen (MPHFs) bilden eine statische Menge S von beliebigen Schlüsseln auf die Menge der ersten |S| natürlichen Zahlen bijektiv ab, d. h., jeder Hashwert wird exakt einmal verwendet. Sie sind in vielen Anwendungen hilfreich, zum Beispiel, um Hashtabellen mit garantiert konstanter Zugriffszeit zu implementieren.
