全球性中学生科普项目Amgen Biotech Experience（以下简称“ABE”）邀请中学生进入实验室体验最新的生物技术和科学发现，旨在新一代科学家和创新者的培养。清华大学-北京大学生命科学联合中心（以下简称“生命中心”）作为ABE中国大陆承办方，于2021年将ABE创新科学教育项目引入中国。2022年8月，生命中心与云南大学生命科学学院（以下简称“云大生科院”）合作，开展了ABE第二期培...
近日，作物病原生物功能基因组研究创新团队在国际知名期刊《基因组生物学》（Genome Biology）上在线发表研究论文“A large-scale genome and transcriptome sequencing analysis reveals the mutation landscapes induced by high-activity adenine base editors in...
ABE for DFA from k-Lin
ABE DFA
2019/6/4
We present the first attribute-based encryption (ABE) scheme for deterministic finite automaton (DFA) based on static assumptions in bilinear groups; this resolves an open problem posed by Waters (CRY...
Compact Adaptively Secure ABE for NC1 from k-Lin
attribute-based encryption adaptive security bilinear maps
2019/2/28
We present compact attribute-based encryption (ABE) schemes for NC1 that are adaptively secure under the k-Lin assumption with polynomial security loss. Our KP-ABE scheme achieves ciphertext size that...
FE for Inner Products and Its Application to Decentralized ABE
functional encryption ABE LWE DDH
2019/1/18
In this work, we revisit the primitive functional encryption (FE) for inner products and show its application to decentralized attribute- based encryption (ABE). Particularly, we derive an FE for inne...
Unbounded ABE via Bilinear Entropy Expansion, Revisited
public-key cryptography attribute-based encryption
2018/2/1
At the core of all of these constructions is a "bilinear entropy expansion" lemma that allows us to generate any polynomial amount of entropy starting from constant-size public parameters; the entropy...
IR-CP-ABE: Identity Revocable Ciphertext-Policy Attribute-Based Encryption for Flexible Secure Group-Based Communication
Group-based Secure Communication Ciphertext-Policy Attribute-Based Encryption ID Revocation
2017/11/20
Ciphertext-Policy Attribute-Based Encryp- tion (CP-ABE) is an access control mechanism over encrypted data and well suited for secure group-based communication. However, it also suffers from the fol- ...
HIR-CP-ABE: Hierarchical Identity Revocable Ciphertext-Policy Attribute-Based Encryption for Secure and Flexible Data Sharing
Attribute-Based Access Control Encryption CP-ABE
2017/11/20
Ciphertext Policy Attribute-Based Encryption (CP- ABE) has been proposed to implement the attribute-based access control model. In CP-ABE, data owners encrypt the data with a certain access policy suc...
ABE with Tag Made Easy: Concise Framework and New Instantiations in Prime-order Groups
Attribute-based encryption Predicate encoding Prime-order bilinear group
2017/9/13
Among all existing identity-based encryption (IBE) schemes in the bilinear group, Wat-IBE proposed by Waters [CRYPTO, 2009] and JR-IBE proposed by Jutla and Roy [AsiaCrypt, 2013] are quite special. A ...
Implementation and Evaluation of a Lattice-Based Key-Policy ABE Scheme
lattice-based cryptography attribute-based encryption GPU computing
2017/6/26
In this paper, we report on our implementation of a lattice-based Key-Policy Attribute-Based Encryption (KP-ABE) scheme, which uses short secret keys. The particular KP-ABE scheme can be used directly...
Securing Abe's Mix-net Against Malicious Verifiers via Witness Indistinguishability
mix-nets witness indistinguishability Benes network
2017/6/9
We show that the simple and appealing unconditionally sound mix-net due to Abe (Asiacrypt'99) can be augmented to further guarantee anonymity against malicious verifiers. This additional guarantee imp...
Dual System Framework in Multilinear Settings and Applications to Fully Secure (Compact) ABE for Unbounded-Size Circuits
Attribute-based encryption Full security Unbounded-size Circuits
2017/2/20
We propose a new generic framework for constructing fully secure attribute based encryption (ABE) in multilinear settings. It is applicable in a generic manner to any predicates. Previous generic fram...
