Constant-Ciphertext-Size Dual Policy Attribute Based Encryption [PDF]
, 2012 Dual-Policy Attribute Based Encryption (DP-ABE), proposed in 2009, is a combination of two variants, Ciphertext Policy-ABE (CP-ABE) and Key Policy-ABE (KP-ABE), where an encryptor can associate the data simultaneously with both a set of objective ...

CP-ABE Scheme with Attribute Revocation Under Environment of Multi-attribute Authority [PDF]
Jisuanji gongcheng, 2018 For the attribute-based encryption scheme,a single authority has the problem of low efficiency and easy disclosure of user keys.Through the establishment of a decentralized attribute authority and agent reencryption technology,a Ciphertext-policy ...

Cloud Access Control Scheme Supporting Multi-authority Centers and Attribute Change [PDF]
Jisuanji gongcheng, 2018 The traditional Ciphertextpolicy Attribute-based Encryption(CP-ABE) systems are based on singleauthority organization,and most of them have the problems of large computation cost,low key maintenance efficiency,and inability to achieve anti-conspiracy ...

Two-Factor Data Access Control With Efficient Revocation for Multi-Authority Cloud Storage Systems
IEEE Access, 2017 Attribute-based encryption, especially for ciphertext-policy attribute-based encryption, can fulfill the functionality of fine-grained access control in cloud storage systems. Since users' attributes may be issued by multiple attribute authorities, multi-

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...
