Cryptanalysis of the Tractable Rational Map Cryptosystem
In this paper, we present the cryptanalysis of a public key scheme based on a system of multivariate polynomial equations, the ”tractable rational map” cryptosystem. We show co...

Token-Controlled Public Key Encryption
Token-controlled public key encryption (TCPKE) schemes, introduced in [1], offer many possibilities of application in financial or legal scenarios. Roughly speaking, in a TCPKE s...

ID-Based Proxy Signature Using Bilinear Pairings
Identity-based (ID-based) public key cryptosystem can be a good alternative for certificate-based public key setting, especially when efficient key management and moderate securit...

Completely Non-malleable Schemes
Abstract An encryption scheme is non-malleable if the adversary cannot transform a ciphertext into one of a related message under the given public key. Although providing a very st...

Secure Communications over Insecure Channels Based on Short Authenticated Strings
Abstract. We propose a way to establish peer-to-peer authenticated communications over an insecure channel by using an extra channel which can authenticate very short strings, e.g....

Identity-Based Hierarchical Strongly Key-Insulated Encryption and Its Application
In this paper, we discuss non-interactive updating of decryption keys in identity-based encryption (IBE). IBE is a public key cryptosystem where a public key is an arbitrary strin...

Digital Signatures Do Not Guarantee Exclusive Ownership
Digital signature systems provide a way to transfer trust from the public key to the signed data; this is used extensively within PKIs. However, some applications need a transfer o...

Group Signature Where Group Manager, Members and Open Authority Are Identity-Based
We present the first group signature scheme with provable security and signature size O(λ) bits where the group manager, the group members, and the Open Authority (OA) are all id...

On the Possibility of Constructing Meaningful Hash Collisions for Public Keys
It is sometimes argued (as in [6]) that finding meaningful hash collisions might prove difficult. We show that at least one of the arguments involved is wrong, by showing that for...
