The form of equation you expect is not usually applied to Shamir's Sharing Scheme. Instead the equation is usually represented as polynomial: $$f\left(x\right)=a_0+a_1x+a_2x^2+a_3x^3+\cdots+a_{k-1}x^{k-1}\,\! \mod p,$$ where $k$ is number of pieces needed to restore the secret; $a_i$ are random coefficients (modulo p) and $p$ is 13 (in your case). ...

We have two kind of search while outsourcing: keyword search and text search. In the keyword search you choose some keywords in your text and preprocess them before outsourcing. In the server(s), there is just one instance of each keyword so there is no duplication problem. There is the literature of searchable encryption that mostly covers this kind of ...

For example, in 3-out-of-4 secret sharing with 2 dishonest parties, once one honest party broadcasts their share, the two dishonest parties can privately collude to reconstruct the secret. Then if they refuse to ...
