Bestie: Very Practical Searchable Encryption with Forward and Backward Securitydevote their efforts to obtaining . and practical performance. However, it is still challenging to design a single DSSE scheme that simultaneously achieves this security, high performance, and real deletion. Note that real deletion is a critical feature to guarantee . stipulated by GDPR. Due to this

Efficient Multi-client Order-Revealing Encryption and Its Applicationsbeyond their lexicographic ordering. However, how to achieve efficient and secure ciphertext comparison for multi-user settings is still a challenging problem. In this work, we propose an efficient multi-client order-revealing encryption scheme (named .) by introducing a new token-based comparison m

Versatile and Sustainable Timed-Release Encryption and Sequential Time-Lock Puzzles (Extended Abstraessage can be accessed. Malavolta and Thyagarajan (CRYPTO’19) recently introduced an interesting variant of TRE called homomorphic time-lock puzzles (HTLPs), making TRE more versatile and greatly extending its applications. Here one considers multiple independently generated puzzles and the homomorp

Multipath TLS 1.3multipath extension of TCP. Costea et al. show that, if one assumes that an adversary cannot attack all communication paths in an active and synchronized way, then one can securely establish a shared key under mild cryptographic assumptions. This holds even if classical authentication methods like c

SyLPEnIoT: Symmetric Lightweight Predicate Encryption for Data Privacy Applications in IoT Environmen heterogeneous resource-constrained devices. One method for protecting privacy is to encrypt data with a pattern or metadata. To prevent information leakage, an evaluation using the pattern must be performed before the data can be retrieved. However, the computational costs associated with typical

Security Analysis of SFrameame, an E2EE mechanism recently proposed to IETF for video/audio group communications over the Internet. Although a quite recent project, SFrame is going to be adopted by a number of real-world applications. We inspected the original specification of SFrame. We found a critical issue that will lead

Attribute-Based Conditional Proxy Re-encryption in the Standard Model Under LWEtting policies and attribute vectors. The fine-grained control of AB-CPRE makes it suitable for a variety of applications, such as cloud storage and distributed file systems. However, all existing AB-CPRE schemes are constructed under classical number-theoretic assumptions, which are vulnerable to q
