On the security of a class of image encryption schemes
— Recently four chaos-based image encryption schemes were proposed. Essentially, the four schemes can be classified into one class, which is composed of two basic parts: permuta...

Practical Short Signature Batch Verification
In many applications, it is desirable to work with signatures that are both short, and yet where many messages from different signers be verified very quickly. RSA signatures sati...

Identity-Based Threshold Proxy Signature from Bilinear Pairings
Abstract. Delegation of rights is a common practice in the real world. We present two identitybased threshold proxy signature schemes, which allow an original signer to delegate he...

Unconditionally Secure Anonymous Encryption and Group Authentication
Anonymous channels or similar techniques that can achieve sender's anonymity play important roles in many applications. However, they will be meaningless if cryptographic prim...

Entity authentication schemes using braid word reduction
Abstract. Artin's braid groups currently provide a promising background for cryptographical applications, since the first cryptosystems using braids were introduced in [2, 3, ...
