A Novel Proactive Multi-secret Sharing Scheme
A proactive secret sharing scheme is a method of sharing a secret among a set of participants. And, the corresponding shadows can be periodically renewed under the premise of never changing the shared secret. However, in the most existing proactive secret sharing schemes, only one secret can be shared during one secret sharing process. The proposed scheme describes PMSS, a new way to share mult...
متن کاملSecret image sharing scheme with hierarchical threshold access structure
A hierarchical threshold secret image sharing (HTSIS) scheme is a method to share a secret image among a set of participants with different levels of authority. Recently, Guo et al. (2012) [22] proposed a HTSIS scheme based on steganography and Birkhoff interpolation. However, their scheme does not provide the required secrecy needed for HTSIS schemes so that some non-authorized subsets of part...

متن کاملA Novel (2,n) Secret Image Sharing Scheme
In this paper, we propose a novel and simple (2, n) secret sharing scheme with precise reconstruction for grayscale, binary and color image. The share construction phase is based on pixel division and XOR operation. The reconstruction is based on XOR and OR operation. The proposed scheme has no pixel expansion and can reconstruct the secret image precisely. This scheme can be directly applied t...
متن کاملA Novel Unconditionally Secure Multi-Secret Sharing Scheme
A multi-secret sharing scheme is a protocol to share some arbitrarily related secrets among a set of participants. A novel ) , ( n k -threshold multi-secret sharing scheme based on an isomorphism is proposed in this paper. The maximum number of secrets that can be shared in the proposed scheme is 2 k which is larger than that of most existing efficient ) , ( n k -threshold multi-secret sharing ...
