The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The central object is the decoupled (public) XOR-type function, f(i,x)=g1(x) XOR p(x XOR i), with p public. Combined with the truncation technique—summing over a t-dimensional subspace L of low bits—it produces F_L(i^l,x^l) whose period in the high (n-t) bits is the secret period s^l, while the low key bits cancel out. Because the public branch can be evaluated offline, the algorithm separates an online preparation phase for the g1 superposition from an offline search phase, which is what converts the attack from online to offline.
What would settle it
Take a concrete TPP-PRF with a non-identity linear map l13 that mixes high and low bit positions, choose small n (e.g., n=6) and t=2, compute F_L of Eq. (8) by exhaustive enumeration, and test whether F_L(i_0^l,x^l)=F_L(i_0^l,x^l XOR s^l) holds for all x^l; if it does not, the central claim for generic TPP-PRFs fails. The same experiment with identity maps should reproduce the period, confirming the split is the load-bearing condition.
Extended reading notes
Core claim
For any decoupled XOR-type function f(i,x)=g1(x) XOR p(x XOR i) coming from a TPP-PRF, summing f over the low t-bit subspace L yields a function F_L(i^l,x^l) that has an (n-t)-bit period s^l exactly when the high bits of the secret state i equal i_0^l. Since p is public, the only part that needs the encryption oracle is g1, and the attack (Algorithm 4) prepares the state for G_L^1 once and then runs amplitude-amplification search offline over candidate i^l, recovering i_0^l and s^l. The paper claims Theorem 4: O(2^t (n-t)) quantum queries in the Q2 model, or O(2^(p+t)) classical queries with O(2^((2n-2t-p)/2) n^3) offline time in Q1, with a balanced optimum at O~(2^((2n-t)/3)). The same meth
Load-bearing premise
The whole truncated-function argument assumes the linear maps used inside the TPP-PRF respect the decomposition into high and low bits, so that summing over the low subspace cancels the low key bits and leaves the high period; for arbitrary n-bit linear maps this is false, and for SoEM22/XopEM it holds only because those maps are identities.
Editorial extensions
If this is right
- XopEM, SoEM22, SUMPIP, and DS-SoEM can be key-recovered by the offline attack.
- In the Q2 model the oracle-query count is reduced from O(2^((n+t)/2) (n-t)) to O(2^t (n-t)); in Q1 both queries and time drop from O~(2^(2n/3)) to O~(2^((2n-t)/3)).
- The attack produces the tradeoff T^2 D = 2^(2n-t) between classical queries D and offline quantum time T, so an attacker can choose a resource profile.
- After recovering the high bits, the remaining t low key bits can be found with an offline period-finding step, giving full key recovery.
- PolyMAC is a new target for the online XOR-type attack, extending the class of vulnerable constructions.
Reading between the lines
- If the linear maps inside a TPP-PRF mix high and low bit positions instead of acting independently on the split, the truncated function is unlikely to have the claimed period; a designer could immunize the construction by ensuring such mixing.
- The same decoupling idea may convert attacks on other two-branch public-permutation constructions (e.g., EDM/EDMD-style functions) into offline attacks whenever one branch is public.
- The tunable truncation parameter t gives a knob that trades recovered key bits against query cost, which could be exploited to fit the attack on resource-constrained quantum devices.

Referee Report
Summary. The paper proposes offline dedicated quantum key-recovery attacks on block cipher constructions built from two parallel permutation-based pseudorandom functions (TPP-PRFs). It first identifies PolyMAC as a new instance vulnerable to the online dedicated attack of Shi et al., then introduces a 'decoupled' p-XOR-type function and presents Algorithm 4, an offline dedicated attack that uses truncation. The claimed results are: in the Q2 model, encryption-oracle query complexity O(2^t(n-t)) instead of O(2^{(n+t)/2}(n-t)); in the Q1 model, a query/time tradeoff T^2 D = 2^{2n-t} balancing at O~(2^{(2n-t)/3}). Concrete instantiations XopEM, SoEM22, SUMPIP, and DS-SoEM are treated, and Theorem 4 is stated for generic decoupled XOR-type functions.
Significance. If the generic claim were fully established, the paper would answer an open question of Shi et al. and improve on both the online dedicated attack and the Q1 results of Sun et al. The offline-separation idea and the concrete identity-map instantiations are genuinely interesting, and the reported Q2 query reduction for SoEM22 and related schemes is plausible. However, the paper's central generic derivation for TPP-PRFs rests on an unstated blockwise-linearity assumption, and the full-key Q1 complexity claim is not supported by the stated algorithms. These issues are load-bearing and need correction before the contribution can be evaluated as claimed.
major comments (3)
- [Section III-B1, Eq. (8)] The derivation of the period of F^L assumes that the n-bit linear maps l13, l23, l14, l24 act blockwise on the p/(n-t-p)/t decomposition. Expressions such as '(l13 y ⊕ l14 k^{l1}_1)∥l14 k^{l2}_1∥0^t' and 'j^{l2} = l13^{-1}l14 k^{l2}_1' are only meaningful if these maps are block-diagonal; for an arbitrary invertible GF(2)-linear map, applying it to a split input mixes the components, and the displayed equality in the lines following Eq. (8) does not follow. In particular, the period condition requires the middle part of the vector s = l13^{-1}l14(k1), which equals l13^{-1}l14(k1^{l2}) only under a blockwise assumption. The same issue affects i^l = l23^{-1}l24 k^l_2. Thus Theorem 4 is not established for generic TPP-PRFs; the supported cases are those where the l maps are identity or at least blockwise on the chosen split.
- [Section III-B2, after Theorem 4] The paper claims that the remaining t-bit key can be recovered by applying the offline Simon algorithm, and the abstract/conclusion state a balanced O~(2^{(2n-t)/3}) classical-query complexity. In the Q1 model, however, running offline Simon on the full n-bit function would require O(2^n) classical queries to prepare the necessary superposition, which dominates O~(2^{(2n-t)/3}). Theorem 4's bound is only for recovering the high (kappa-t) bits (and the period). If the authors intend only partial-key recovery, the abstract and conclusion should say so; if they claim full-key recovery, the stated complexity is incorrect.
- [Section III-A1, Eq. (3)] The PolyMAC formula uses undefined notation 'k2_1' and 'k2_3', and the claimed period relation s=(k1⊕k3)(β0⊕β1) with α_i=k1(β0⊕β1) or k3(β0⊕β1) is not derivable from the displayed equation as written. Since PolyMAC is presented as the first new instance answering Shi et al.'s open question, this is a load-bearing part of the paper and must be corrected and expanded with a clear definition of the scheme.
minor comments (5)
- [Eq. (8)] The domain of F^L is given as {0,1}^{n-t} × {0,1}^{n-t-p} × {0,1}^p, but the first argument is written as i^l∥j^{l2}, which has length 2n-2t-p. The types should be made consistent.
- [Section III-B1] The notation l=l1∥l2 is used both for the index in Eq. (8) and for the original key l; this is confusing. Also, 'l1' and 'l2' are used as both bit lengths and strings.
- [Eq. (3)] If 'k2_1' and 'k2_3' are intended to be k1^2 and k3^2, this should be written unambiguously with a definition of the finite-field multiplication.
- [Algorithm 4] The prepared state notation is missing parentheses: it should clearly indicate tensor products over c' copies of the superposition. The line breaks in the description also make the algorithm harder to read.
- [Eq. (6)] The condition 'l_ij ≠ 0' should be supplemented by invertibility or a precise blockwise condition; the paper's later truncation arguments rely on such structure.
Circularity Check
No circularity: the offline attack applies known Simon/offline-Simon/dedicated-XOR techniques to TPP-PRFs; claimed periods are derived explicitly, with the only self-citations used as baselines or auxiliary verification.
full rationale
The central derivation (Section III-B1, Eqs. 7-8) constructs a p-XOR-type function f from the TPP-PRF and explicitly verifies the period s^{l1}=l13^{-1}l14 k1^{l1} by expanding F_L at the claimed key. This is a mathematical derivation from the construction, not an assumption of the conclusion. Algorithm 4/Theorem 4 combine the offline Simon algorithm [34] and Shi et al.'s truncated dedicated attack [37]; the query counts follow from the algorithm structure, not from parameters fitted to the target. The self-citations [35,36] are used for baseline comparisons and for a periodicity fact that the text also derives in place; they are not invoked as an unverified uniqueness theorem and are not the only support for the central claim. The known gap concerning the high/low-bit split assumption for general linear maps l_{ij} is a correctness concern about the scope of the derivation, not a circular reduction: Eq. (8) implicitly assumes blockwise action, and if that fails F_L need not be periodic, but the derivation is still not equivalent by definition to its output. Hence no circular step is identified.
Assumptions & free parameters
free parameters (2)
- truncation parameter t =
0 < t < n (e.g., t = n/2 for the balanced Q1 tradeoff)
- partition parameter p =
0 < p < n-t; balanced choice p+t = (2n-t)/3
assumptions (5)
- standard math Simon's algorithm and the offline Simon's algorithm (Bonnetain et al. 2019) are correct under the stated promise of a unique hidden period.
- domain assumption The encryption oracle can be queried in superposition in Q2 and classically in Q1; both models permit arbitrary offline quantum computation after the online phase.
- domain assumption The random permutations P1, P2 (and block cipher E in PolyMAC) behave so that the periodicity of f(i,x) is unique or near-unique for the actual key.
- ad hoc to paper The linear maps l13, l23, l14, l24 in the generic TPP-PRF derivation can be truncated blockwise: applying them to x^l||0^t XOR u preserves the split into high and low parts as used in Eq. (8).
- domain assumption Preparing |psi_GL> from O(2^p) classical queries can be done with a unitary that writes GL(x^l) into a quantum register at negligible extra cost (Algorithm 6).

abstract
Quantum cryptanalysis is essential for evaluating the security of cryptographic systems against the threat of quantum computing. Recently, Shi {\it et al.} introduced a dedicated quantum attack on block cipher constructions based on XOR-type functions, which greatly reduces the required resources (including circuit depth, width, and the number of gates) compared to the parallel Grover-meets-Simon algorithm. Here, our contribution is in two aspects. On the one hand, we discover new cryptographic structures amenable to this attack: PolyMAC and constructions based on two parallel permutation-based pseudorandom functions (TPP-PRFs), including XopEM, SoEM22, SUMPIP, and DS-SoEM, thereby answering Shi {\it et al.}' s open question. On the other hand, for constructions based on TPP-PRFs, we break the obstacle that this attack relies on online query by constructing decoupled XOR-type functions, then propose an offline quantum attack on them. Compared to previous results, our offline attack exhibits significantly reduced query complexity. Specifically, the number of queries to the encryption oracle is reduced from $O(2^{(n+t)/2}\cdot (n-t))$ to $O(2^{t}\cdot (n-t))$ in the quantum query model, where $0<t<n$, $t$ is a truncation parameter, and $n$ is the input length of constructions. Further, we enable its implementation in the classical query model, optimizing both the classical query complexity and time complexity from $\tilde O(2^{2n/3})$ to $\tilde O(2^{(2n-t)/3})$ for $0<t \leq n/2$.
