looking for BKZ earliest algorithm and its application in cryptography I am reading lattice based cryptography for my master thesis,
I am looking for the earliest version of BKZ algorithm, and its applications in cryptography, to understand it very well, I already know about LLL algorithm.
and thanks in advance
BKZ was described in Lattice basis reduction: improved practical algorithms and solving subset sum problems by  C. P. Schnorr, M. Euchner in 1994. As the title suggests, it was first used for solving the subset sum problem.
