Kowalczyk and Wee proposed an adaptively secure attribute encryption scheme that supports $NC^1$ circuits. However, the circuit depth increases because this scheme supports only circuits with fan-in 2, which increases the key length and computational complexity of the key generation and decryption algorithms. To improve efficiency, we designed a secret sharing scheme for circuits with fan-in $n$, and we proposed a key-policy ABE scheme that supports circuits with fan-in $n$. We also designed pebbling rules for secret sharing in circuits with fan-in $n$, improving the compactness of the security reduction. Finally, we proved the adaptive security of the scheme by using a piecewise guessing framework and dual-system encryption. Compared with existing schemes, our scheme reduces the key size, improves the efficiency of the key generation algorithm and the decryption algorithm and provides tighter security reduction.<\/jats:p>","DOI":"10.1093\/comjnl\/bxac105","type":"journal-article","created":{"date-parts":[[2022,7,23]],"date-time":"2022-07-23T21:39:35Z","timestamp":1658612375000},"page":"2554-2573","source":"Crossref","is-referenced-by-count":1,"title":["Adaptively Secure KP-ABE For Circuits With Fan-In n And Fan-Out 1"],"prefix":"10.1093","volume":"66","author":[{"given":"Keshuo","family":"Sun","sequence":"first","affiliation":[{"name":"PLA SSF Information Engineering University , Zhengzhou 450000 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haiying","family":"Gao","sequence":"additional","affiliation":[{"name":"PLA SSF Information Engineering University , Zhengzhou 450000 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2022,7,24]]},"reference":[{"key":"2023101421212038700_ref1","doi-asserted-by":"crossref","first-page":"457","DOI":"10.1007\/11426639_27","volume-title":"Advances in Cryptology -
