Abstract
A technique includes generating a direct anonymous attestation (DAA)-based signature to prove an electronic device is a member of a group. Generating the signature includes determining a reciprocal of a prime modulus, and determining the reciprocal of the prime modulus comprises left bit shifting a Barrett multiplier by a predetermined number of bits and multiplying a result of the left bit shifting of the Barrett multiplier with the prime modulus.
