Learn about homomorphic encryption in this comprehensive tutorial presented by Shai Halevi at Crypto 2011 in Santa Barbara, CA. Explore the concept of computing on encrypted data, understand the organization of the tutorial, and delve into the fundamentals of Fully Homomorphic Encryption (FHE). Examine the Gentry 2009 blueprint, encryption from Linear ECCSA, and different input encoding methods. Discover additive homomorphism, code living in a ring, and various instantiations. Investigate bootstrapping techniques, performance aspects of the blueprint, and advanced topics beyond the initial framework. Gain insights into Chimeric Homomorphic Encryption as presented in GH 2011b.
