On Efficiently Transferring the Linear Secret-Sharing Scheme Matrix in Ciphertext-Policy Attribute-Based Encryption
Ciphertext-Policy Attribute-Based Encryption(CP-ABE) is a system for realizing complex access control on encrypted data, in which attributes are used to describe a user’s credentials and a party encrypting data determines a policy over attributes for who can decrypt. In CP-ABE schemes, access policy is attached to the ciphertext to be the input of the decryption algorithm. An access policy can ...
متن کاملUsing Ciphertext Policy Attribute Based Encryption for Verifiable Secret Sharing
Threshold secret sharing schemes are used to divide a given secret by a dealer in parts such that no less than the threshold number of shareholders can reconstruct the secret. However, these schemes are susceptible to the malicious behavior of a shareholder or a dealer. To prevent such attacks, it is necessary to make a provision for verification of the integrity of the shares distributed by th...
متن کاملSecurity Analysis of a Hash-Based Secret Sharing Scheme
Secret sharing schemes perform an important role in protecting se-cret by sharing it among multiple participants. In 1979, (t; n) threshold secret sharing schemes were proposed by Shamir and Blakley independently. In a (t; n) threshold secret sharing scheme a secret can be shared among n partic-ipants such that t or more participants can reconstruct the secret, but it can not be reconstructed b...
متن کاملRational Multi-Secret Sharing Scheme Based On Bit Commitment Protocol
In this paper we mainly focus on the fraud problem among the players and the shortcomings of multisecret sharing existed in rational secret sharing schemes. Based on the exited schemes and the related knowledge such as bit commitment agreement, we proposed a new rational multi-secret sharing scheme that has high security. In our scheme, we take an identity authentication for the dealer in distr...
متن کاملOn the design and security of a lattice-based threshold secret sharing scheme
In this paper, we introduce a method of threshold secret sharing scheme (TSSS) in which secret reconstruction is based on Babai's nearest plane algorithm. In order to supply secure public channels for transmitting shares to parties, we need to ensure that there are no quantum threats to these channels. A solution to this problem can be utilization of lattice-based cryptosystems for these channe...
