We present new and efficient key-recovery chosen-ciphertext attacks on NTRUencrypt. Our attacks are somewhat intermediate between chosen-ciphertext attacks on NTRUencrypt previousl...
We present a new encryption scheme which is secure against adaptive chosenciphertext attack (or CCA2-secure) in the standard model (i.e. without the use of random oracle). Our sch...
We present a chosen-ciphertext attack against the public key cryptosystem called NTRU. This cryptosystem is based on polynomial algebra. Its security comes from the interaction of ...
We present a new approach for creating chosen ciphertext secure encryption. The focal point ork is a new abstraction that we call Detectable Chosen Ciphertext Security (DCCA). Int...
Abstract. The paradigms currently used to realize symmetric encryption schemes secure against adaptive chosen ciphertext attack (CCA) try to make it infeasible for an attacker to f...
