TCC 2025 will take place in Aarhus, Denmark on December 2-5, 2025. TCC 2025 is organized by the International Association for Cryptologic Research (IACR). The proceedings will be published by Springer in the LNCS series. Papers presenting original research on foundational and theoretical aspects of cryptography are sought. For more information about TCC, see the TCC manifesto. 

 The Theory of Cryptography Conference deals with the paradigms, approaches, and techniques used to conceptualize natural cryptographic problems and provide algorithmic solutions to them. More specifically, the scope of the conference includes, but is not limited to the:

    study of known paradigms, approaches, and techniques, directed towards their better understanding and utilization
    discovery of new paradigms, approaches and techniques that overcome limitations of the existing ones
    formulation and treatment of new cryptographic problems
    study of notions of security and relations among them
    modeling and analysis of cryptographic algorithms
    study of the complexity assumptions used in cryptography

TCC is dedicated to providing a premier venue for the dissemination of results within its scope. The conference aims to provide a meeting place for researchers and to be instrumental in shaping the identity of the theoretical cryptography community. With these goals in mind, TCC 2025 is planned to be an in-person meeting. At least one author of each accepted paper is required to present the paper in person at the conference, unless there are extenuating circumstances approved by the chairs.
