How to Correct Errors in Multi-Server PIR
Private Information Retrieval information theoretic error correcting
2019/5/22
Suppose that there exist a user and ℓ servers S1,…,Sℓ. Each server Sj holds a copy of a database x=(x1,…,xn)∈{0,1}n, and the user holds a secret index i0∈{1,…,n}. A b error correcting T...
