The bit decomposition unit (11) generates a bit representation lap {a.sub.0}, . . . , {a.sub.λ−1} of a. A first bit sequence generator (12) calculates {a′.sub.i}={a.sub.i}∨{a.sub.i+1} to generate {a′.sub.0}, . . . , {a′.sub.λ′−1}. A flag sequence generator (13) generates {x.sub.0}, . . . , {x.sub.λ′−1} indicating a most significant bit of {a′.sub.0}, . . . , {a′.sub.λ′−1}. A normalization multiplier generator (14) generates [c′] by bit-connecting {x.sub.λ′−1}, . . . , {x.sub.0}. A second bit sequence generator (15) sets {a″.sub.i}={a.sub.2i} to generate {a″.sub.0}, . . . . A flag calculator (16) sums {x.sub.j}{a′.sub.j} to calculate a share value {r}. A normalization unit (18) calculates [b]: =[c′][c′][2a] when r=1 and [b]: =[c′][c′][a] when r=0. A inverse square root calculator (19) calculates [w]: =[1/√b]*√2 when r=1, and [w]: =[1/√b] when r=0. An inverse normalization unit (20) multiplies [1/√a]: =[w][c′].

A bit sequence generator (13) calculates {y.sub.i}:={x.sub.2i} XOR {x.sub.2i+1} to generate {y.sub.0}, . . . , {y.sub.λ′−1}. A flag calculator (14) calculates an exclusive logical sum of all {x.sub.j} to calculate [r] for each odd j. A public value multiplier setting-unit (16) sets r′ that becomes √2 when λ is an odd and 1 when λ is an even. A normalization multiplier generator (17) bit-connects {y.sub.0}, . . . to generate [c′].

A square root calculator (20) calculates [w]:=[√b]*(r′/√2) when r=1, and [w′]:=[√b]*r′ when r=0. An inverse normalizer (21) calculates [w][c′] and performs λ′ bits right-shift.

A method for device authentication comprises receiving, by processing hardware of a first device, a message from a second device to authenticate the first device. The processing hardware retrieves a secret value from secure storage hardware operatively coupled to the processing hardware. The processing hardware derives a validator from the secret value using a path through a key tree, wherein the path is based on the message, wherein deriving the validator using the path through the key tree comprises computing a plurality of successive intermediate keys starting with a value based on the secret value and leading to the validator, wherein each successive intermediate key is derived based on at least a portion of the message and a prior key. The first device then sends the validator to the second device.
