Multi-party Indirect Indexing and Applications [chapter]

Matthew Franklin, Mark Gondree, Payman Mohassel
Advances in Cryptology – ASIACRYPT 2007  
We develop a new multi-party generalization of Naor-Nissim indirect indexing, making it possible for many participants to simulate a RAM machine with only poly-logarithmic blow-up.  ...  Underlying our approach is a new multi-party variant of oblivious transfer which may be of independent interest. Proof (Proof (sketch)).  ...  We develop a multiparty generalization of Naor-Nissim indirect indexing, and show that our methods have many cryptographic applications.  ...
