Algorithm for SIS and MultiSIS problems
This work addresses a key computational bottleneck in cryptography, offering a more efficient solution for lattice-based security problems, though it appears incremental as it builds on known approaches.
The authors tackled the SIS problem, which has many cryptographic applications, by proposing a new algorithm that achieves sub-exponential complexity for certain parameters, improving upon existing exponential methods.
SIS problem has numerous applications in cryptography. Known algorithms for solving that problem are exponential in complexity. A new algorithm is suggested in this note, its complexity is sub-exponential for a range of parameters.
