Le mode IGE utilisé dans le protocole personnalisé de Telegram n'a pas été entièrement étudié en termes de sécurité post-quantique. Dans cette lettre, nous montrons que le mode IGE n'est pas sécurisé par IND-qCPA par l'algorithme de Simon, en supposant que le chiffrement par bloc sous-jacent est une fonction pseudo-aléatoire sécurisée standard (sPRF). Sous l’hypothèse plus forte que le chiffrement par bloc est une fonction pseudo-aléatoire à sécurité quantique (qPRF), la sécurité IND-qCPA du mode IGE est prouvée en utilisant un lemme unidirectionnel pour masquer.

Abstract: IGE mode used in Telegram's customized protocol has not been fully investigated in terms of post-quantum security. In this letter, we show that IGE mode is IND-qCPA insecure by Simon's algorithm, assuming that the underlying block cipher is a standard-secure pseudorandom function (sPRF). Under a stronger assumption that the block cipher is a quantum-secure pseudorandom function (qPRF), IND-qCPA security of IGE mode is proved using one-way to hiding lemma.
