A Filter Bank View of Block and Stream Ciphers
نویسنده
چکیده
Vaidyanathan suggested the use of filter banks with coefficients in finite fields as stream ciphers. We show how to break those ciphers. A more general class of ciphers is introduced, which includes many well-known block ciphers, like DES, IDEA, etc. These ciphers are derived from filter banks over group rings.

Stream ciphers and the eSTREAM project
Stream ciphers are an important class of symmetric cryptographic algorithms. The eSTREAM project contributed significantly to the recent increase of activity in this field. In this paper, we present a survey of the eSTREAM project. We also review recent time/memory/data and time/memory/key trade-offs relevant for the generic attacks on stream ciphers.
متن کاملA General Encryption Scheme Based on MDS Code ( Extended Summary )
Many applications, such as wireless communications, high speed multimedia data streaming systems and sensor networks, call for strong ciphers with low computation complexity and high speed in encryption and decryption. Additive stream ciphers usually have lower computation complexity and thus provide higher encryption/decryption speed than block ciphers. An additive stream cipher usually encryp...
متن کاملBlock and Stream Cipher Based Cryptographic Algorithms: A Survey
The encryption algorithms are designed to provide integrity and confidentiality of the messages. Modern cryptosystems are classified into three categories such as Block ciphers, Stream cipher and Hybrid ciphers of Hummingbird. This paper details about various types of block ciphers and stream ciphers. In this paper we also present the hybrid model of hummingbird and its comparison among other c...
متن کاملTowards Stream Ciphers for Efficient FHE with Low-Noise Ciphertexts
Symmetric ciphers purposed for Fully Homomorphic Encryption (FHE) have recently been proposed for two main reasons. First, minimizing the implementation (time and memory) overheads that are inherent to current FHE schemes. Second, improving the homomorphic capacity, i.e. the amount of operations that one can perform on homomorphic ciphertexts before bootstrapping, which amounts to limit their l...
متن کاملAnalysis of Lightweight Stream Ciphers
Stream ciphers are fast cryptographic primitives to provide confidentiality of electronically transmitted data. They can be very suitable in environments with restricted resources, such as mobile devices or embedded systems. Practical examples are cell phones, RFID transponders, smart cards or devices in sensor networks. Besides efficiency, security is the most important property of a stream ci...
