The two volume-set, LNCS 8042 and LNCS 8043, constitutes the refereed proceedings of the 33rd Annual International Cryptology Conference, CRYPTO 2013, held in Santa Barbara, CA, USA, in August 2013. The 61 revised full papers presented in LNCS 8042 and LNCS 8043 were carefully reviewed and selected from numerous submissions. Two abstracts of the invited talks are also included in the proceedings. The papers are organized in topical sections on lattices and FHE; foundations of hardness; cryptanalysis; MPC - new directions; leakage resilience; symmetric encryption and PRFs; key exchange; multi linear maps; ideal ciphers; implementation-oriented protocols; number-theoretic hardness; MPC - foundations; codes and secret sharing; signatures and authentication; quantum security; new primitives; and functional encryption.

This book constitutes the refereed proceedings of the 32nd Annual International Cryptology Conference, CRYPTO 2012, held in Santa Barbara, CA, USA, in August 2012. The 48 revised full papers presented were carefully reviewed and selected from 225 submissions. The volume also contains the abstracts of two invited talks. The papers are organized in topical sections on symmetric cryptosystems, secure computation, attribute-based and functional encryption, proofs systems, protocols, hash functions, composable security, privacy, leakage and side-channels, signatures, implementation analysis, black-box separation, cryptanalysis, quantum cryptography, and key encapsulation and one-way functions.

TCC 2008, the 5th Theory of Cryptography Conference, was held in New York, New York, March 19-21, 2008, at New York University. TCC 2008 was sp- soredbytheInternationalAssociationforCryptologicResearch(IACR)andwas organizedincooperationwiththeDepartmentofComputerScienceatNewYork University and the Courant Institute for Mathematical Sciences. The General Chairs of the conference were Yevgeniy Dodis and Victor Shoup. The conference received 81 submissions, of which the Program Committee selected34forpresentationattheconference.Theauthorsoftwopapersthen- cidedto mergetheir papers, resulting in a totalof33 presentedpapers.The Best Student Paper Award was given to Paul Valiant for his paper "Incrementally Veri?able Computation or Knowledge Implies Time/Space E?ciency." These proceedings consist of revised versions of the presented papers. The revisions were not reviewed. The authors bear full responsibility for the contents of their papers. The conference programalso included four special events: an invited talk - titled "Randomness Extractors and Their Cryptographic Applications" by Salil Vadhan; a tutorial entitled "Bridging Cryptography and Game Theory: Recent Results and Future Directions," given by Jonathan Katz (with an accom- nying tutorial in the proceedings); a panel discussion on "Game Theory and Cryptography: Towards a Joint Point of View?" with Tal Rabin as moderator and Jonathan Katz, Silvio Micali, and Moni Naor as panelists; and a Rump Session chaired by Anna Lysyanskaya.
