Encryption Schemes Secure against Chosen-Ciphertext Selective Opening Attacks
Imagine many small devices send data to a single receiver, encrypted using the receiver’s public key. Assume an adversary that has the power to adaptively corrupt a subset of the...

Type-Safe Disks
We present the notion of a type-safe disk (TSD). Unlike a traditional disk system, a TSD is aware of the pointer relationships between disk blocks that are imposed by higher layer...

Certificateless signcryption
Certificateless cryptography achieves the best of the two worlds: it inherits from identity-based techniques a solution to the certificate management problem in public-key encrypti...

Provable Security of KASUMI and 3GPP Encryption Mode f8
Within the security architecture of the 3GPP system there is a standardised encryption mode f8 based on the block cipher KASUMI. In this work we examine the pseudorandomness of the...

Threshold Public-Key Encryption with Adaptive Security and Short Ciphertexts
Threshold public-key encryption (TPKE) allows a set of users to decrypt a ciphertext if a given threshold of authorized users cooperate. Existing TPKE schemes suffer from either lo...
