Identity-Based Traitor Tracing
We present the first identity-based traitor tracing scheme. The scheme is shown to be secure in the standard model, assuming the bilinear decision Diffie-Hellman (DBDH) is hard in...

New Chosen-Ciphertext Attacks on NTRU
We present new and efficient key-recovery chosen-ciphertext attacks on NTRUencrypt. Our attacks are somewhat intermediate between chosen-ciphertext attacks on NTRUencrypt previousl...

Passive-Only Key Recovery Attacks on RC4
Abstract. We present several weaknesses in the key scheduling algorithm of RC4 when the secret key contains an initialization vector – a cryptographic scheme typically used by th...
