Apuf technology has an intra-puf error rate of 3.5% ( average error when the same cell is subject to repetitive queries to generate responses) an inter-puf error rate of 37.5% (average error when the cells of one device are compared with the cells of different devices) . the cryptographic protocol use keys generated from the pufs at various length: 32-bit, 64-bit, 128-bit, and 256-bit for each key length, use poisson calculator to respond: what is the frr if the threshold t1 is more than10 errors . what is the far if the threshold t2 is less than 14 errors? find t1 for frr< 1ppm (part per million) find t2 for far〈1ppm
