Tighter security proofs for post-quantum key encapsulation mechanism in the multi-challenge setting

Due to the threat posed by quantum computers, a series of works investigate the security of cryptographic schemes in the quantum-accessible random oracle model (QROM) where the adversary can query the random oracle in superposition. In this paper, we present tighter security proofs of a generic tran...
