Abstract

See full text

A signature generation apparatus generates a signature for a message m from the i-th user, and computes any two or three of a[1]μ[x] (mod n), a[2]μ[s] (mod n), and wμ[t] (mod l) are in parallel. For this reason, the signature generation apparatus is provided with a plurality of fast arithmetic units (sub-IPs) within the IP core. The individual sub-IPs are connected to each other via a narrow-band, single-layer local bus.
