Our work supports arbitrary TMs as signing policies in the sense that the TMs can accept signing attribute strings of unbounded polynomial length and there is no limit on their running time, description size, or space complexity. Moreover, we are able to achieve input-specific running time for the signing algorithm. All other known expressive ABS schemes could at most support signing policies realizable by either arbitrary polynomial-size circuits or TMs having a pre-determined upper bound on the running time. 2023-04-26T02:56:12Z 2023-04-26T02:56:12Z 2023 Book https://link.springer.com/article/10.1007/s10623-022-01163-8 https://dlib.phenikaa-uni.edu.vn/handle/PNK/8317 en application/pdf Springer
