Threshold Encryption into Multiple Ciphertexts
We propose (T, N) multi-ciphertext scheme for symmetric encryption. The scheme encrypts a message into N distinct ciphertexts. The knowledge of the symmetric key allows decryption ...

Revisiting Fully Distributed Proxy Signature Schemes
In a proxy signature scheme, a potential signer delegates his capabilities to a proxy signer, who can sign documents on behalf of him. The recipient of the signature verifies both...

Hash-Based Key Management Schemes for MPEG4-FGS
We propose two symmetric-key management schemes for the encryption of scalable compressed video content. The schemes are applicable to MPEG-4 Fine Grain Scalability video coding. O...

Signature Schemes and Anonymous Credentials from Bilinear Maps
Abstract. We propose a new and efficient signature scheme that is provably secure in the plain model. The security of our scheme is based on a discrete-logarithm-based assumption p...

On the Impossibility of Three-Move Blind Signature Schemes
We investigate the possibility to prove security of the well-known blind signature schemes by Chaum, and by Pointcheval and Stern in the standard model, i.e., without random oracle...
