Most ancient Chinese padlocks are key-operated locks with splitting springs, and partially keyless letter-combination locks. They can be characterized based on the types of locks, ...
A Hierarchical Identity Based Encryption (HIBE) system is anonymous if the ciphertext reveals no information about the recipient’s identity. create it. While there are multiple c...
We introduce a new lattice-based cryptographic structure called a bonsai tree, and use it to resolve some important open problems in the area. Applications of bonsai trees include...

In this paper we analyze the security of systems based on modular additions, rotations, and XORs (ARX systems). We provide both theoretical support for their security and practical...
We answer the question of Reyhanitabar et al. from FSE’09 of constructing a domain extension scheme for enhanced target collisionresistant (eTCR) hash functions with sublinear ke...
