Certificateless public key encryption with equality test
Information Sciences, 2018In this paper, we present the concept of certificateless public key encryption with equality test (CL-PKEET), which integrates certificateless public key cryptography (CL-PKC) into public key encryption with equality test (PKEET) to solve the key escrow ...

Public-key authenticated encryption with keyword search revisited: Security model and constructions
Information Sciences, 2020In cloud era, it is necessary to store sensitive data in an encrypted form. This arises the interesting and challenging problem of searching on encrypted data.

In this chapter, we introduce public-key encryption. We first consider the motivation behind the concept of public-key cryptography and introduce the hard problems on which popular public-key encryption schemes are based. We then discuss two of the best-known public-key cryptosystems, RSA and ElGamal.

A key problem of the symmetric cryptosystems that we have described so far is key distribution and key management. When Alice and Bob use such a system, they must exchange a secret key before they can secretly communicate. For the key-exchange, they need, for example, a secure channel or a courier.

Multipurpose Public-Key Encryption
2017We propose a new type of public-key schemes, that simultaneously satisfies selective opening (SO) security, key-dependent message (KDM) security and leakage-resilience. Our construction can be instantiated under the quadratic residuosity (QR) assumption or decisional composite residuosity (DCR) assumption.

This paper proposes a public-key cryptosystem and a short password encryption mode, where traditional hardness assumptions are replaced by specific refinements of the CAPTCHA concept called Decisional and Existential CAPTCHAs.
