But litigation may be the most effective means–...

Quantum secret sharing is a scheme for encoding a quantum state (the secret) into multiple shares and distributing them among several participants. If a sufficient number of shares are put together, then the secret can be fully reconstructed. If an insufficient number of shares are put together however, no information about the secret can be revealed. In quantum ramp secret sharing, partial inf...

recently, baghery et al. [1, 2] presented some attacks on two rfid protocols, namely yoon and jung et al. protocols, and proposed the improved version of them. however, in this note, we show that the improved version of the jung et al. protocol suffers from desynchronization attack and the improved version of the yoon's protocol suffers from secret disclosure attack. the success probabilit...

Secret sharing allows split control over the secret. Secret parts known as secret shares are distributed to different shareholders (locations). Secret can be recovered upon combination of sufficient number of shares. Research into theoretical foundations, development of widespread applications, as well as, new attacks resulted in great need for extra features of existing schemes. We describe ex...
