【摘要】:該文設(shè)計了一種基于SRAM物理不可克隆函數(shù)(PUFs)的高效真隨機種子發(fā)生器。通過將不提供熵值的穩(wěn)定節(jié)點和提供低熵值的噪聲節(jié)點篩除,只選用能夠提供較高熵值的噪聲節(jié)點來生成滿熵種子,大幅降低需要處理的數(shù)據(jù)量,提高節(jié)點數(shù)據(jù)的處理效率。通過測試SRAM PUFs內(nèi)部噪聲節(jié)點的振蕩特性,提出篩選出SRAM PUFs內(nèi)部高熵值的噪聲節(jié)點的最佳策略,最終基于此策略設(shè)計出真隨機種子發(fā)生器。該設(shè)計可以產(chǎn)生128~256 bit長度的滿熵的種子且處理的節(jié)點數(shù)據(jù)量只有當前方法的0.5%~4%。生成的種子滿足NIST架構(gòu)的隨機數(shù)生成器要求,產(chǎn)生的偽隨機數(shù)全部通過了隨機數(shù)檢測。與現(xiàn)有設(shè)計相比,該文提出的真隨機種子發(fā)生器是一種高效的、適用范圍較廣的設(shè)計。
[Abstract]:In this paper, an efficient true random seed generator based on SRAM physical nonclonal function (PUFs) is designed, which removes the stable nodes without entropy and the noise nodes with low entropy. Only the noise nodes which can provide high entropy value are used to generate full entropy seeds, which greatly reduce the amount of data to be processed. By testing the oscillation characteristics of SRAM PUFs internal noise nodes, the optimal strategy of selecting the noise nodes with high entropy value in SRAM PUFs is put forward. Finally, a true random seed generator is designed based on this strategy. The full entropy seed of bit length and the amount of node data processed are only 0.5% of the current method. The generated seeds meet the requirements of the random number generator of the NIST architecture. All the pseudo-random numbers are tested by random number. Compared with the existing design, the true random seed generator presented in this paper is an efficient and widely used design.
