Steady Blade Element Momentum Methodtext, all the involved secret keys are required. For multi decryptor setting, decryption is a protocol with minimal interaction among parties. However, all prior schemes supporting the protocol are not secure in public channel against a passive external adversary who can see any public information n

Introduction to Watanabe Bayesian Theory,ed and the development of quantum computers has been promoted. In fact, quantum-secure systems have been studied in both areas of public key cryptography and symmetric key cryptography. This paper studies quantum security of message authentication codes (MACs) with advanced functionality of compress

A Framework for UC-Secure Commitments from Publicly Computable Smooth Projective Hashing,f zero-knowledge proof system for a language. While initially used to build efficient chosen-ciphertext secure public-key encryption, they found numerous applications in several other contexts. In this paper, we revisit the notion of SPHFs and introduce a new feature (a third mode of hashing) that a
