Anonymous Multi-Receiver Identity-Based Authenticated Encryption with CCA Security
In a multi-receiver encryption system, a sender chooses a set of authorized receivers and sends them a message securely and efficiently, as the message is well encrypted and only one ciphertext corresponding to the message is generated no matter how many receivers the sender has chosen. It can be applied to video conferencing systems, pay-per-view channels, remote education, and so forth. Due t...
متن کاملProvably CCA-Secure Anonymous Multi-Receiver Certificateless Authenticated Encryption
Multi-receiver encryption allows a sender to choose a set of authorized receivers and send them a message securely and efficiently. Only one ciphertext corresponding to the message is generated regardless of the number of receivers. Thus it is practical and useful for video conferencing systems, pay-per-view channels, distance education, and so forth. In 2010, for further protecting receivers’ ...
متن کاملImproved Anonymous Multi-receiver Identity-Based Encryption
In 2010, Fan et al. proposed an efficient anonymous multi-receiver identity-based encryption scheme. This scheme allows a sender to send an encrypted message to a set of designated receivers while preserving receiver anonymity. The scheme is highly efficient for each receiver as it requires only two pairing operations. However, we found that the scheme failed to protect receiver anonymity and t...
متن کاملCryptanalysis and improvements of an anonymous multi-receiver identity-based encryption scheme
In 2010, Fan et al. presented an anonymous multi-receiver identity-based encryption scheme where they adopt Lagrange interpolating polynomial mechanism. They showed that their scheme makes it impossible for an attacker or any other message receiver to derive the identity of a message receiver such that the privacy of every receiver can be guaranteed. They also formally showed that every receive...
متن کاملAn Anonymous Multi-Receiver Encryption Based on RSA
With the rapid development of information and network technologies, communication security has become an important issue in many applications. There are many public-key based encryption schemes proposed in the literature. Network applications are no longer just one-toone type of communication; but it involves multiple receivers (>1) (e.g., multicast transmission). One-to-one type encryption is ...
