Task

Secure Multiparty Computation Alice holds a private Boolean vector A with 10 Boolean entries ({0,1}10) while Bob holds another private Boolean vector B with another 10 Boolean entries ({0,10). Design and implement a protocol using the Fairplay to securely compute the scalar product. 

  • B without sharing their inputs to each other.
  • The scalar product computation should be converted to garbled circuits using SFDL.
  • Fairplay secure function evaluation
  • Readme file for running Fairplay SFE: 
     

Tasks: (a) Alice generates random Boolean entries for A while Bob generates random Boolean entries for B. (3 points) (b) Write the SFDL program for Alice and Bob. (12 points) (c) Compile it for Alice and Bob, and run the protocol (communication is integrated in Fairplay). (5 points) (d) Report the input Boolean vectors, the SFDL program, SHDL circuit, and output results A. Application of Homomorphic Encryption (40 points) Alice holds a private matrix A (nonnegative integer entries) with size 5 x 8 while Bob holds a private matrix B (nonnegative integer entries) with size 8 x 4. Design and implement a two-party protocol to securely compute the product A x B. Hint: Homomorphic Encryption (e.g., PalIlier Cryptosystem which is a public key-based scheme) can be used to design the protocol.
