Abstract

With the deepening of research, how to construct a fully homomorphic signcryption scheme based on standard assumptions is a problem that we need to solve. For this question, recently, Jin et al. proposed a leveled fully homomorphic signcryption scheme from standard lattices. However, when verifying, it is supposed to unsigncrypt first as they utilize sign-then-encrypt method. This leads to users being unable to verify the authenticity of the data first, which resulting in the waste of resources. This raises another question of how to construct an fully homomorphic signcryption (FHSC) scheme with public verifiability. To solve this problem, we propose a leveled fully homomorphic signcryption scheme that can be publicly verified and show its completeness, IND-CPA security, and strong unforgeability.

一个可公开验证的水平全同态签名加密方案

随着研究的深入，如何在标准假设的基础上构造一个完全同态的签名加密方案是我们需要解决的一个问题。针对这个问题，Jin等人最近提出了一种基于标准格的水平全同态签名加密方案。然而，在验证时，应该先解除签名，因为他们使用先签名后加密的方法。这导致用户无法首先验证数据的真实性，从而造成资源的浪费。这就提出了如何构造具有公共可验证性的完全同态签名加密(FHSC)方案的另一个问题。为了解决这一问题，我们提出了一种可公开验证的分层全同态签名加密方案，该方案具有完备性、IND-CPA安全性和强不可伪造性。
