Nettet24. sep. 2024 · When \nu =2\mu , we call this a length-doubling PRG. In our case, we use such a PRG to expand hash values. 3.3 SPHINCS^+ Framework SPHINCS^+ is a stateless hash-based signature framework [ 2] designed based on the SPHINCS [ 3] scheme and has been submitted to the third round of the NIST PQC standardization …

Nettettion (PRF) F:{0,1}κ×{0,1}κ →{0,1}κ instead of a length doubling PRG G.Since G can be implemented via two calls to F but the converse direction is not known, formulating positive (asymptotic) results in terms of the number of PRG calls makes them stronger. 2 The number of OTs used by such protocols is typically smaller than the circuit size. Nettet20. okt. 2024 · The GGM-PRF relies on a length-doubling pseudorandom generator (PRG), and its implementation is highly sequential, resulting in a circuit depth linear in the input length.
