“…Another line of research as a modification of RN cryptosystem that ensures the complete error correction capability of the underlying codes without affecting the security of the cryptosystem is introduced in other studies . In these schemes, the intentional error vector added to the encoded word is generated based on a secret key and is removed during decryption prior to decoding in order to preserve the error correction capability of the code.…”

A modified RN scheme with low complexity using binary QC‐LDPC codes and LFSR‐based intentional error vector for securing communication in energy constrained applications such as WSN is proposed in Stuart et al In this scheme, resistance to CPA is achieved by changing the encoding matrix and intentional error vector during each data transmission.

“…Even though all these schemes provides reliability and privacy simultaneously, none of these schemes are designed to provide homomorphism over encryption, which is required for concealed data aggregation in WSN. This is due to the fact that the schemes in other studies either introduces nonlinearity in encryption process or changes the encryption matrix with every message transmission to enhance security.…”

“…At the same time, resistance to CPA is attained by changing the encryption matrix at every instant of aggregation because it is required to preserve linearity only during a particular instant of aggregation. The LFSR keystream generator presented in Stuart et al cannot be adopted as such in homomorphic aggregation as the randomness properties provided by the intentional error vector may get spoiled after data aggregation. In the work discussed in this paper, we first derived the conditions required to preserve the randomness properties during aggregation, through mathematical analysis.…”

“…Based on this analysis, a novel design of LFSR‐based intentional error vector generator is presented, which ensures that the randomness and security properties are preserved in the aggregated ciphertext. Moreover, in contrast to all other schemes, nonbinary QC‐LDPC codes are used in the proposed scheme for better reliability while supporting data aggregation.…”

Data aggregation is an efficient method to reduce the energy consumption in wireless sensor networks (WSNs). However, data aggregation schemes pose challenges in ensuring data privacy in WSN because traditional encryption schemes cannot support data aggregation. Homomorphic encryption schemes are promising techniques to provide end to end data privacy in WSN. Data reliability is another main issue in WSN due to the errors introduced by communication channels. In this paper, a symmetric additive homomorphic encryption scheme based on Rao-Nam scheme is proposed to provide data confidentiality during aggregation in WSN. This scheme also possess the capability to correct errors present in the aggregated data. The required security levels can be achieved in the proposed scheme through channel decoding problem by embedding security in encoding matrix and error vector. The error vectors are carefully designed so that the randomness properties are preserved while homomorphically combining the data from different sensor nodes. Extensive cryptanalysis shows that the proposed scheme is secure against all attacks reported against private-key encryption schemes based on error correcting codes. The performance of the encryption scheme is compared with the related schemes, and the results show that the proposed encryption scheme outperforms the existing schemes. KEYWORDSdata aggregation, data confidentiality, homomorphic encryption, Rao-Nam encryption, wireless sensor network INTRODUCTIONWith the advancement of Internet of things (IoT), the popularity of wireless sensor networks (WSN) has increased tremendously. WSNs support a wide variety of applications ranging from military to civilian. WSN consists of a large collection of sensor nodes (SNs) that have limited capabilities to sense, process, and communicate the data. Because SNs are energy constrained devices, it is inefficient to send the collected data from sensors directly to the sink. Moreover, in many scenarios, the sink only needs the derivative of collected data such as sum, mean, variance, etc instead of the exact value from all sensors. Data aggregation techniques help to achieve this goal in an energy efficient manner. 1 Data privacy is a major challenge in WSN, and it will become further complicated by the adoption of data aggregation methods. This is due to the fact that if traditional encryption schemes are used to preserve the privacy of the data sent from Int J Commun Syst. 2019;32:e3832.wileyonlinelibrary.com/journal/dac

An instance of the framework for cryptographic security enhancement of symmetric-key encryption employing a dedicated error correction encoding is addressed. The main components of the proposal are: (i) a dedicated error correction coding and (ii) the use of a dedicated simulator of the noisy channel. The proposed error correction coding is designed for the binary erasure channel where at most one bit is erased in each codeword byte. The proposed encryption has been evaluated in the traditional scenario where we consider the advantage of an attacker to correctly decide to which of two known messages the given ciphertext corresponds. The evaluation shows that the proposed encryption provides a reduction of the considered attacker’s advantage in comparison with the initial encryption setting. The implementation complexity of the proposed encryption is considered, and it implies a suitable trade-off between increased security and increased implementation complexity.
