“…Based on the works of Boneh et al and Menezes et al, the required computational time sequence of different operations is T H ≈ T M < T J < T R < T E ≤ T Q < T P . Thus, the scheme is efficient than others during the key extraction and encryption and better than schemes in other works and nearly equal to Cocks's scheme during decryption of a message. On the other side, in QRDVS scheme, the computation time for a given input message mainly depends on the time required to generate and verify the signature.…”

With the rapid developments in embedded sensor technology, the internet of things (IoT) becomes the most focused research trend in the recent years. However, the integration of such technology into mobile crowdsensing networks results in many security challenges. Data confidentiality and authenticity are the two key privacy concerns in any IoT‐based crowdsensing environment. Focusing on these security issues, we present a new cryptographic protocol to meet those challenges. Our protocol is based on two new schemes; first is an encryption scheme, which utilizes the idea of identity‐based encryption, and the second is a designated verifier signature scheme. Here, we design a pairing‐free and random oracle‐free encryption scheme with a small‐size public parameter where the anonymity of IoT‐recipient is maintained. Besides, the proposed designated verifier signature scheme facilitates the signatory to send a signature without sending the original message. The security of the encryption and signature schemes are proven in the standard security model based on the difficulty of proposed modified interactive quadratic residuosity “(MIQR)” assumption. Moreover, the schemes are compared with other relevant schemes and found several merits in terms of functionality. Thus, the proposed protocol is applicable in many IoT‐enabled crowdsourcing environments where the authenticity of confidential data is the major concern.

“…Their work achieves the security against the One-way Chosen Ciphertext Attack (OW-CCA). There are some extensions of PKEET which offer the fine or flexible grain authorization and stronger security [13,12,6,9,10,8]. To achieve the stronger security, the authorization mechanism is adopted to these PKEET schemes.…”

“…In [10], Ma et al provided a solution to the PKEET in multi-user setting by delegating the equality test to a fully trusted proxy. Later, Ma [8] proposed an identity-based PKEET (IBEET). These works improved the security of PKEET to IND-CCA security, while private keys are kept secret.…”

Testing if two ciphertexts contain the same plaintext is an interesting cryptographic primitive. It is usually referred to as equality test of encrypted data or equality test. Abstract. Testing if two ciphertexts contain the same plaintext is an interesting cryptographic primitive. It is usually referred to as equality test of encrypted data or equality test. One of attractive applications of equality test is for encrypted database systems, where the database server hosts the encrypted databases and users can query if the plaintext embedded in a ciphertext on a database is equal to that in the queried ciphertext without decryption. Although it is not hard to achieve with the pairing-based cryptography, the security against the insider attack (by the database server) is a challenging task. In this paper, we propose a novel equality test scheme aiming to solve the problem. Our scheme adopts the identity-based cryptography. We prove the security of our scheme in the random oracle model.
