Time-Specific Encryption
This paper introduces and explores the new concept of Time-Specific Encryption (TSE). In (Plain) TSE, a Time Server broadcasts a key at the beginning of each time unit, a Time Inst...

Distributed Private-Key Generators for Identity-Based Cryptography
An identity-based encryption (IBE) scheme can greatly reduce the complexity of sending encrypted messages. However, an IBE scheme necessarily requires a private-key generator (PKG)...

Mechanism-Based PKI - A Real-Time Key Generation from Fingerprints
- This paper proposes a "mechanism-based PKI", in which only a mechanism for generating user's private keys is installed on a smart card. The private key is generate...

The SPEED Cipher
Abstract. SPEED is a private key block cipher. It supports three variable parameters: (1) data length — the length of a plaintext/ciphertext of SPEED can be 64, 128 or 256 bits. ...

A Lattice-Based Public-Key Cryptosystem
In 1998, Cai and Cusick proposed a lattice-based public-key cryptosystem based on the similar ideas of the Ajtai-Dwork cryptosystem, but with much less data expansion. However, th...

Software Smart Cards via Cryptographic Camouflage
A sensitive point in public key cryptography is how to protect the private key. We outline a method of protecting private keys using cryptographic camouflage. Specifically, we do ...

Secure Password-Based Protocol for Downloading a Private Key
We present protocols that allow a user Alice, knowing only her name and password, and not carrying a smart card, to "log in to the network" from a "generic" wo...

Key Recovery and Message Attacks on NTRU-Composite
NTRU is a fast public key cryptosystem presented in 1996 by Hoffstein, Pipher and Silverman of Brown University. It operates in the ring of polynomials Z[X]/(XN − 1), where the ...

Algebraic Cryptanalysis of McEliece Variants with Compact Keys
In this paper we propose a new approach to investigate the security of the McEliece cryptosystem. We recall that this cryposystem relies on the use of error-correcting codes. Since...

A Hierarchical Key-Insulated Signature Scheme in the CA Trust Model
In key-insulated cryptography, there are many private keys with different indexes and a single, fixed public key. When the trust model includes multiple Certification Authoritie...
