The pith
KEM-IES replaces the classical key agreement in ECIES with a post-quantum KEM and adds Ascon to resist quantum attacks while improving efficiency on embedded hardware.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
KEM-IES is constructed by incorporating a PQC-based KEM into the integrated encryption framework of ECIES to provide resistance against quantum attacks, and by integrating the Ascon algorithm to enhance computational efficiency and support use in embedded systems, with the proposal validated through implementation on a Raspberry Pi 4 and performance comparisons.
What carries the argument
KEM-IES, the scheme that substitutes a post-quantum key encapsulation mechanism for ECIES key agreement and layers Ascon authenticated encryption.
Load-bearing premise
That substituting a PQC KEM for the classical key-agreement step in ECIES and layering Ascon preserves the original security guarantees while delivering measurable efficiency gains on embedded hardware without introducing new attack surfaces.
What would settle it
A successful quantum attack on the KEM component of KEM-IES or benchmark results from Raspberry Pi 4 showing higher runtime or memory use than ECIES would disprove the claimed benefits.
read the original abstract
The Elliptic Curve Integrated Encryption Scheme (ECIES) is widely regarded as a practical method and has been adopted by multiple standards. However, the advancement of quantum computing technologies poses potential security risks to ECIES. Therefore, this study proposes a Key Encapsulation Mechanism-Based Integrated Encryption Scheme (KEM-IES), which enhances resistance to quantum attacks by incorporating a Post-Quantum Cryptography (PQC)-based Key Encapsulation Mechanism (KEM). Furthermore, the study integrates the Ascon algorithm, released by the National Institute of Standards and Technology (NIST) in August 2025, to further improve computational efficiency and enable applicability to embedded systems. The proposed KEM-IES and its Ascon-based variant are implemented on a Raspberry Pi 4, and evaluations are conducted to compare the performance of ECIES and KEM-IES.

A structured set of objections, weighed in public.
Referee Report
Summary. The manuscript proposes a Key Encapsulation Mechanism-Based Integrated Encryption Scheme (KEM-IES) obtained by substituting a post-quantum KEM for the key-agreement step of ECIES, thereby claiming enhanced resistance to quantum attacks. It further integrates the Ascon algorithm to improve computational efficiency and suitability for embedded systems. The authors state that both KEM-IES and its Ascon variant were implemented on a Raspberry Pi 4 and that performance comparisons with ECIES were conducted.
Significance. If the missing security argument, concrete construction, and performance data were supplied and shown to be sound, the work could provide a practical route to quantum-resistant integrated encryption for constrained devices, leveraging a NIST-selected lightweight primitive. At present the absence of any supporting evidence prevents assessment of whether the substitution preserves ECIES security properties or actually yields efficiency gains.
major comments (3)
- Abstract: The text asserts that 'the proposed KEM-IES and its Ascon-based variant are implemented on a Raspberry Pi 4, and evaluations are conducted to compare the performance of ECIES and KEM-IES,' yet the manuscript contains no implementation description, threat model, performance metrics, or comparison tables, leaving all efficiency and applicability claims unsupported.
- Abstract: No concrete post-quantum KEM is named and no integration details are given (e.g., which ECIES components are retained or replaced, how the KEM output is used for key derivation, or the resulting security model). Consequently the central claim that quantum resistance is achieved while preserving original guarantees cannot be verified.
- Abstract: The statement that Ascon integration 'further improve[s] computational efficiency and enable[s] applicability to embedded systems' is presented without any description of Ascon's role (authenticated encryption, hash, or otherwise), any side-channel analysis, or any hardware-specific measurements, rendering the efficiency claim unsubstantiated.
Simulated Author's Rebuttal
We thank the referee for the careful reading and constructive comments. We agree that the abstract, as currently written, is too high-level and does not supply the concrete details needed to substantiate the claims. We will perform a major revision that expands the abstract, adds dedicated sections on the construction, implementation, threat model, and performance evaluation, and supplies the missing evidence.

Referee: [—] Abstract: The text asserts that 'the proposed KEM-IES and its Ascon-based variant are implemented on a Raspberry Pi 4, and evaluations are conducted to compare the performance of ECIES and KEM-IES,' yet the manuscript contains no implementation description, threat model, performance metrics, or comparison tables, leaving all efficiency and applicability claims unsupported.
Authors: We accept the observation. The abstract summarizes results that appear in later sections of the full manuscript, but those sections were not sufficiently referenced or excerpted in the abstract. In the revision we will (i) briefly mention the Raspberry Pi 4 platform and the measured metrics already in the abstract, (ii) add a new “Implementation and Evaluation” section that describes the software environment, the threat model (passive quantum adversary plus active classical adversary), the exact performance metrics collected (encryption/decryption latency, memory footprint, energy consumption), and (iii) include comparison tables and figures against ECIES. revision: yes

Referee: [—] Abstract: No concrete post-quantum KEM is named and no integration details are given (e.g., which ECIES components are retained or replaced, how the KEM output is used for key derivation, or the resulting security model). Consequently the central claim that quantum resistance is achieved while preserving original guarantees cannot be verified.
Authors: We agree that the abstract omits these specifics. The revised manuscript will name the concrete KEM (ML-KEM, the NIST-standardized module-lattice KEM) and will contain a dedicated “Construction” section that (a) states that the KEM replaces the elliptic-curve Diffie-Hellman step of ECIES, (b) shows how the KEM shared secret is fed into the same KDF used by ECIES to derive the symmetric key, (c) retains the original ECIES MAC and symmetric encryption steps (or their Ascon replacement), and (d) sketches the security argument: IND-CCA security of the KEM plus the standard ECIES assumptions yields quantum-resistant confidentiality while preserving the integrity properties of the original scheme. revision: yes

Authors: We acknowledge the point. In the revision we will clarify that Ascon-128 is used as the authenticated-encryption primitive in place of the symmetric cipher/MAC combination of classic ECIES. The new “Ascon Integration” subsection will describe the exact API usage, provide a constant-time implementation note addressing side-channel concerns on the Raspberry Pi 4, and report concrete cycle counts and memory figures that demonstrate the efficiency improvement over the AES-based baseline. revision: yes
Circularity Check
No derivation chain or equations present; circularity analysis inapplicable
full rationale
The paper consists solely of a high-level abstract proposing KEM-IES by substituting a PQC KEM into ECIES and layering Ascon. No equations, derivations, fitted parameters, security reductions, or self-citations appear. Claims are design assertions without mathematical structure that could reduce to inputs by construction. No load-bearing steps of any enumerated kind exist.
