“…For example, our scheme is aimed at application scenarios we discuss in the section of introduction. By comparing our scheme with the latest scheme [18], it is found that both of two schemes have the same security features but our scheme has less computational overhead and shorter ciphertext length. The computational complexity of modular multiplication operation is much higher than other operations in the scheme.…”

In the field of social survey of misconduct and legal consultation, the features of confidentiality, integrity, deniable authentication, and non-repudiation are needed for the sake of preserving privacy. For this special kind of application scenario, we propose an efficient deniable authentication encryption scheme. Our scheme can achieve the four secure features in a single logical step. And compared with the latest scheme, our scheme reduces the computational cost of encryption by about 30%, reduces computational cost of decryption by about 50%, and reduces the length of ciphertext by about 33%. Its security is shown in the random oracle model. INDEX TERMS Deniable authentication, privacy protection, deniable authenticated encryption.

Heterogeneous deniable authenticated encryption for location-based services

The location-based services can provide users with the requested location information. But users also need to disclose their current location to the location-based service provider. Therefore, how to protect user’s location privacy is a major concern. In this paper, we propose a heterogeneous deniable authenticated encryption scheme called HDAE for location-based services. The proposed scheme permits a sender in a public key infrastructure environment to transmit a message to a receiver in an identity-based environment. Our design utilizes a hybrid encryption method combing the tag-key encapsulation mechanism (tag-KEM) and the data encapsulation mechanism (DEM), which is well adopted for location-based services applications. We give how to design an HDAE scheme utilizing a heterogeneous deniable authenticated tag-KEM (HDATK) and a DEM. We also construct an HDATK scheme and provide security proof in the random oracle model. Comprehensive analysis shows that our scheme is efficient and secure. In addition, we give an application of the HDAE to a location-based services system.

Deniable authentication (DA) is a protocol in which a receiver can generate an authenticator that is probabilistically indistinguishable from a sender. DA can be applied in many scenarios that require user privacy protection. To enhance the security of DA, in this paper, we construct a new deniable authenticated encryption (DAE) scheme that realizes deniable authentication and confidentiality in a logical single step. Compared with existing approaches, our approach provides proof of security and is efficient in terms of performance analysis. Our scheme is in an identity-based environment; thus, it avoids the public key certificate-based public key infrastructure (PKI). Moreover, we provide an example that shows that our protocol is applicable for e-voting systems.
