Web18 de jul. de 2016 · One significant impediment to adoption of identity-based cryptography was its dependence on a centralized public-key infrastructure. The set of procedures needed to create, manage, distribute, use, store, revoke, and manage keys all take place locally to the user, then need to be broadcasted to the centralized public-key server. Web9 de abr. de 2024 · Currently, attribute-based encryption (ABE) is a promising solution to the above problems . The prototype of attribute-based encryption was first presented in 2005 , where the user’s public key is some role-based descriptive attributes that characterize the identity and user’s private key and ciphertext are also related to attributes. inconsistency\\u0027s 1d
