Cloud storage services are an important application of cloud computing. An increasing number data owners store their on platforms. Since platforms far away from users, security and privacy protection very issues that need to be addressed. Identity-based broadcast encryption (IBBE) is method provide for services. Because the side channel attacks may lead disclosure key information cryptographic ...

Multi-receiver public key encryption is important in insecurity and open network environment and has been applied in many scenarios such as first pay television system, streaming media services and so on. To avoid costly management of certificate and settle the matter of key escrow, we combine multi-receiver public key encryption with certificateless cryptography, and then present the notion, s...

In future internet architectures, end-to-end (E2E) secured personal messaging is essential. So here an E2E user two-way authenticated double encrypted messaging architecture based on hybrid RSA for private messaging is proposed. Our P2P protocol works over TCP protocol for creating direct connections in between, with IPv4 broadcast options to discover peers on the same LAN. Our protocol impleme...

Abstract Broadcast Encryption (BE) is public-key encryption allowing a sender to encrypt message by specifing recipients, and only the specified recipients can decrypt message. In several BE applications, since privacy of allowed access often as important confidentiality message, anonymity introduced an additional but security requirement for BE. Kiayias Samari (IH 2013) presented asymptotic lo...
