Nettet9. okt. 2024 · In such a cipher-text policy attribute-based encryption (CP-ABE); the cipher-text associates to the access policy while that of the secret key was associated with the attribute set. In this proposed construction, we discuss Linear Integer Secret Sharing scheme (LISS) in which access policy of the encryptor is distributed over a LISS matrix … Netteta positive integer gap parameter g. Ramp secret sharing scheme necessarily requires shares of length ‘=g. Other than the bound related to secret length ‘, the share lengths of ramp schemes can not go below a quantity that depends only on the gap ratio g=N. In this work, we study secret sharing in the extremal case of bit-long shares and ...
