  - "The evasive LWE assumption, proposed by Wee [Eurocrypt’22 Wee] for constructing
    a lattice-based optimal broadcast encryption, has shown to be a powerful assumption,
    adopted by subsequent works to construct advanced primitives ranging from ABE
    variants to obfuscation for null circuits. However, a closer look reveals significant
    differences among the precise assumption statements involved in different works,
    leading to the fundamental question of how these assumptions compare to each other.
    In this work, we initiate a more systematic study on evasive LWE assumptions:\r\n(i)
    Based on the standard LWE assumption, we construct simple counterexamples against
    three private-coin evasive LWE variants, used in [Crypto’22 Tsabary, Asiacrypt’22
    VWW, Crypto’23 ARYY] respectively, showing that these assumptions are unlikely
    to hold.\r\n\r\n(ii) Based on existing evasive LWE variants and our counterexamples,
    we propose and define three classes of plausible evasive LWE assumptions, suitably
    capturing all existing variants for which we are not aware of non-obfuscation-based
    counterexamples.\r\n\r\n(iii) We show that under our assumption formulations,
    the security proofs of [Asiacrypt’22 VWW] and [Crypto’23 ARYY] can be recovered,
    and we reason why the security proof of [Crypto’22 Tsabary] is also plausibly
    repairable using an appropriate evasive LWE assumption.@eng"
