Public-Key Encryption Based on LPN

Scrambling-based speech encryption via compressed sensing

Conventional speech scramblers have three disadvantages, including heavy communication overhead, signal features underexploitation, and low attack resistance. In this study, we propose a scrambling-based speech encryption scheme via compressed sensing (CS). Distinguished from conventional scramblers, the above problems are solved in a unified framework by utilizing the advantages of CS. The pre...

Public-key Encryption with Masking Public-key Encryption with Masking

Timed-release encryption, first mentioned by May [12] and discussed by Rivest, Shamir, and Wanger [15], is a cryptographic primitive which enables us to “send a message into the future.” We take a simple approach, called public-key encryption with masking, in order to realize this requirement. In our model, the sender first encrypts a plaintext and “masks” the ciphertext, then send it the recei...

Pairing-Based Multi-Recipient Public Key Encryption

The growth of the Internet has triggered tremendous opportunities for broadcast service. However, the security issue of the broadcast has not been properly addressed. In this paper, we propose a new multi-recipient public key encryption scheme called ”Pairing-Based Multi-Recipient Encryption” (PBMRE)to achieve a secure broadcast transmission. In PBMRE, a ciphertext encrypted by an encryption ke...

Timed-Release Public Key Based Authenticated Encryption

In this paper, we formally define a notion of timed-release public key based authenticated encryption (TR-PKAE). In addition to standard time-independent security properties (such as IND-CCA security for confidentiality and ciphertext/plaintext unforgeability), TR-PKAE introduces requirements such as timed-release receiver confidentiality (IND-RTR-CCA), which precludes the receiver from decrypt...
