Round 1

Reviewer 1 Report

This paper proposes two many-to-one heterogeneous signcryption schemes and two one-to-many heterogeneous signcryption schemes for secure V2I communication in VANETs, which construct secure channels between heterogeneous vehicles and a RSU to support confidentiality, authentication, integrity and non-repudiation services. Numerical and theoretical analyses are conducted to demonstrate the computation cost, communication cost, storage and ciphertext length of the schemes are better than the existing ones.

 

This paper is clearly presented and well organized. The contribution can be further improved, e.g. the paper says that it is not easy to design the schemes, but does not elaborate the innovation of their designs - such as what are the challenges, how you overcome them, etc.

Reviewer 2 Report

In the paper, several heterogeneous signcryption schemes for V2I communications are proposed. Some comments/suggestions follow:
 
Abstract:  
 
   - Line 16: V2I acronym should not be directly used in abstract. It would be better to use "Vehicle to Infrastructure (V2I)".
   - Line 24: Typo: "numberical" should be "numerical".
 
Section 1:  
 
    - Line 83: Typo: "Numberical" should be "Numerical".
    - Line 103: In order to introduce IBC acronym, "identity-based cryptosystem.." should be "Identity-Based Cryptosystem (IBC)".
 
 
Section 4:
    - Line 264: In IBC-KG, "then the PKG computes its corresponding secret key s_kid .. , and sends it to the RSU in a secure way.". How is this "secure way" implemented ?. Can you provide a practical example for the case of V2I ?.
 
References:  
 
    - Reference 11: Typo "hybird" should be "hybrid".
 
* There are several typos and grammatical errors in the manuscript. It should be thorougly revised.
