This book constitutes the refereed proceedings of the Cryptographer's Track at the RSA Conference 2023, CT-RSA 2023, held in San Francisco, CA, USA, in April 2023. The 26 full papers presented in this volume were carefully reviewed and selected from 76 submissions. The conference presents papers on subjects such as Cryptographic Implementations, Quantum Cryptanalysis, Advanced Public-Key Encryption, Tools for Privacy-Enhancing Technologies, Symmetric Cryptanalysis, Multiparty Protocols, Digital Signatures, Fault Attacks and Side Channels, Heuristic Approaches, Symmetric-Key Constructions, and Key Agreement.

The two-volume proceedings set LNCS 13940 and 13941 constitutes the refereed proceedings of the 26th IACR International Conference on Practice and Theory of Public Key Cryptography, PKC 2023, which took place in March 2023 in Atlanta, GA, USA. The 49 papers included in these proceedings were carefully reviewed and selected from 183 submissions. They focus on all aspects of public-key cryptography, covering Post-Quantum Cryptography, Key Exchange and Messaging, Encryption, Homomorphic Cryptography and other topics.

The five-volume set, LNCS 14081, 140825, 14083, 14084, and 14085 constitutes the refereed proceedings of the 43rd Annual International Cryptology Conference, CRYPTO 2023. The conference took place at Santa Barbara, USA, during August 19-24, 2023. The 124 full papers presented in the proceedings were carefully reviewed and selected from a total of 479 submissions. The papers are organized in the following topical sections: Part I: Consensus, secret sharing, and multi-party computation; Part II: Succinctness; anonymous credentials; new paradigms and foundations; Part III: Cryptanalysis; side channels; symmetric constructions; isogenies; Part IV: Faster fully homomorphic encryption; oblivious RAM; obfuscation; secure messaging; functional encryption; correlated pseudorandomness; proof systems in the discrete-logarithm setting.

Zusammenfassung: The four-volume proceedings set LNCS 14601-14604 constitutes the refereed proceedings of the 27th IACR International Conference on Practice and Theory of Public Key Cryptography, PKC 2024, held in Sydney, NSW, Australia, April 15-17, 2024. The 54 papers included in these proceedings were carefully reviewed and selected from 176 submissions. They focus on all aspects of signatures; attacks; commitments; multiparty computation; zero knowledge proofs; theoretical foundations; isogenies and applications; lattices and applications; Diffie Hellman and applications; encryption; homomorphic encryption; and implementation

The Cryptographers’ Track (CT-RSA) is a research conference within the RSA conference, the largest, regularly staged computer security event. CT-RSA 2004 was the fourth year of the Cryptographers’ Track, and it is now an established venue for presenting practical research results related to cryptography and data security. The conference received 77 submissions, and the program committee sel- ted 28 of these for presentation. The program committee worked very hard to evaluate the papers with respect to quality, originality, and relevance to cryp- graphy. Each paper was reviewed by at least three program committee members. Extended abstracts of the revised versions of these papers are in these proc- dings. The program also included two invited lectures by Dan Boneh and Silvio Micali. I am extremely grateful to the program committee members for their en- mous investment of time and e?ort in the di?cult and delicate process of review and selection. Many of them attended the program committee meeting during the Crypto 2003 conference at the University of California, Santa Barbara.

This book constitutes the proceedings of the 20th International Conference on Detection of Intrusions and Malware, and Vulnerability Assessment, DIMVA 2023, held in Hamburg, Germany, in July 2023. The 12 full papers and 1 short paper presented in this volume were carefully reviewed and selected from 43 submissions. The papers are organized in thematical sections named: Side Channels Attacks; Security and Machine Learning; Cyber Physical System Security; Security Issues when Dealing with Users; Analysis of Vulnerable Code; Flow Integrity and Security.
