Description

Many of the cryptographic schemes used to secure today’s communication were not designed with the functionality and the security requirements in mind that come along with tomorrow’s envisioned use-cases. Cryptography which is future-proof, however, needs to consider a setting with a potentially huge number of users to which data is communicated simultaneously and even with restriction who is allowed to read what. Additionally, it needs to be flexible enough to work on both ends of the spectrum, i.e., resource constrained IoT devices as well as cloud-powered services. What is more, one needs to even consider the increasing importance of cryptographic schemes which are resilient against strong attacks (such as key-leakage or subverted implementations) as well as new security aspects such as readiness for a post-quantum era. For the latter, one also needs to reconsider the choice of standard schemes (such as signatures), which still need to find their way into deployments. This workshop features talks which cover the following aspects of future-proof secure communication (1) flexibility in terms of decryption capabilities (e.g., attribute-based encryption), (2) strong security features (e.g., forward security by design) and (3) security in the presence of powerful quantum computers, i.e., schemes that provide post-quantum security (e.g., post-quantum secure signature schemes).
