This book constitutes the refereed post-conference proceedings of the 5th International Conference on Cryptology and Information Security in Latin America, LATINCRYPT 2017, held in Havana, Cuba, in September 2017. The 20 papers presented were carefully reviewed and selected from 64 submissions. They are organized in the following topical sections: security protocols; public-key implementation; cryptanalysis; theory of symmetric-key cryptography; multiparty computation and privacy; new constructions; and adversarial cryptography.

FastSoftwareEncryption2009wasthe16thin a seriesofworkshopsonsymm- ric key cryptography. Starting from 2002, it is sponsored by the International Association for Cryptologic Research (IACR). FSE 2009 was held in Leuven, Belgium, after previous venues held in Cambridge, UK (1993, 1996), Leuven, Belgium (1994, 2002), Haifa, Israel (1997), Paris, France (1998, 2005), Rome, Italy (1999), New York, USA (2000), Yokohama, Japan (2001), Lund, Sweden (2003), New Delhi, India (2004), Graz, Austria (2006), Luxembourg, Lux- bourg (2007), and Lausanne, Switzerland (2008). The workshop's main topic is symmetric key cryptography, including the designoffast andsecuresymmetrickeyprimitives,suchas block ciphers,stream ciphers, hash functions, message authentication codes, modes of operation and iteration, as well as the theoretical foundations of these primitives. This year, 76 papers were submitted to FSE including a large portion of papers on hash functions, following the NIST SHA-3 competition, whose wo- shop was held just after FSE in the same location. From the 76 papers, 24 were accepted for presentation. It is my pleasure to thank all the authors of all s- missions for the high-quality research, which is the base for the scienti?c value of the workshop. The review process was thorough (each submission received the attention of at least three reviewers), and at the end, besides the accepted papers, the Committee decided that the merits of the paper "Blockcipher-Based Hashing Revisited" entitled the authors to receive the best paper award. I wish to thank all Committee members and the referees for their hard and dedicated work.

The 3-volume-set LNCS 13275, 13276 and 13277 constitutes the refereed proceedings of the 41st Annual International Conference on the Theory and Applications of Cryptographic Techniques, Eurocrypt 2022, which was held in Trondheim, Norway, during 30 May - 3 June, 2022. The 85 full papers included in these proceedings were accepted from a total of 372 submissions. They were organized in topical sections as follows: Part I: Best Paper Award; Secure Multiparty Computation; Homomorphic Encryption; Obfuscation; Part II: Cryptographic Protocols; Cryptographic Primitives; Real-World Systems Part III: Symmetric-Key Cryptanalysis; Side Channel Attacks and Masking, Post-Quantum Cryptography; Information-Theoretic Security.
