WebOur Results We present a KP-ABE construction in the prime-order set-ting which supports LSSS/MSP access policies. The construction’s full se-curity is based on DLIN. 1.1 Other Related Work Additional work on ABE in the bilinear setting includes various construc-tions of KP-ABE and CP-ABE schemes (e.g. [4, 30, 16]), schemes supporting WebIn CP-ABE, the ciphertext is associ-ated with an access policy and the user key is labeled with a set of attributes. Since its inception, CP-ABE has attracted a lot of attention for fine-grained access control in cloud environments. In [10–16], different CP-ABE schemes are proposed for fine-grained access control of data in the cloud. fury warrior classic talents
