Implicit Key-Stretching Security of Encryption Schemesly a negligible impact on key recovery seems to have remained uninvestigated. Therefore, it is interesting to study if “implicit” key stretching may come for free as an inherent property of popular schemes..We define an encryption scheme as “fully key-stretching-secure” if an adversary that sees pla

Related-Key Differential Cryptanalysis of GMiMC Used in Post-Quantum Signaturesnderlying building block in post-quantum signature schemes, we then construct two kinds of iterative related-key differentials, from which not only do we explore its security margin against related-key attacks, but also collision attacks on its key space can be performed. For example, for GMiMC inst

Exploring Encrypted Keyboards to Defeat Client-Side Scanning in End-to-End Encryption Systemss that impact the user’s privacy and security. Therefore, it is not end-to-end encryption when there are censorship mechanisms and backdoors in end-to-end encrypted applications. In this paper, we shed light on this hugely problematic issue by introducing an encrypted keyboard that works as a system

Public Key Encryption with Hierarchical Authorized Keyword Searchs in general. In this work, we introduce a novel cryptographic primitive called public key encryption with hierarchical authorized keyword search (PEHAKS) to solve this problem. In contrast to PEAKS, the proposed primitive enables authorized users to further hierarchically delegate their power of ge

Private Evaluation of a Decision Tree Based on Secret Sharingted with heavy cryptographic primitives such as modular exponentiation. We propose a new method to privately index arrays that avoids the use of public/symmetric key cryptosystem, typically associated with private array indexing protocols. The results of our experiments show that our solution has a

A Performance Evaluation of IPsec with Post-Quantum CryptographyrongSwan. Our evaluation targets a variety of PQC KEM algorithms, including NIST Round 3 finalists (i.e., Kyber, NTRU, and Saber) and algorithms developed in Korea and China. The performance evaluation shows the trade-offs between the security level and performance for individual PQC algorithms in t
