In this paper, an authentication code with double arbiters over symplectic geometry is constructed, and the relevant parameters and the probabilities of successful attacks are calculated. The model not only prevents deception from the opponent and members of the system, but also effectively limits the attacks of single arbiter. Moreover, the collusion attacks from arbiters and participators are difficult to succeed.展开更多

And a simple Von Neumann corrector as post processing is also realized to improve data randomness. Prototypes have been implemented and fabricated in 0.18 μm complementary metal oxide semiconductor（CMOS） technology with a wide range of supply voltage from 1.8 V to 3.6 V. The circuit occupies 4 500 μm2, and dissipates minimum 160 μW of power with sampling frequency of 20 MHz. Output bit rate range is from 100 kbit/s to 20 Mbit/s. Statistical test results, which were achieved from the die Hard battery of tests, demonstrate that output random numbers have a well characteristic of randomness.展开更多
