텔레그램의 맞춤형 프로토콜에 사용되는 IGE 모드는 포스트퀀텀 보안 측면에서 완전히 조사되지 않았습니다. 이 편지에서는 기본 블록 암호가 표준 보안 의사 난수 함수(sPRF)라고 가정하고 Simon의 알고리즘에 따라 IGE 모드가 IND-qCPA 안전하지 않음을 보여줍니다. 블록 암호가 qPRF(양자 보안 의사 난수 함수)라는 강력한 가정 하에서 IGE 모드의 IND-qCPA 보안은 보조 정리를 숨기는 단방향을 사용하여 입증됩니다.

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.
