Hardware Framework for the Rabbit Stream Cipher
Rabbit is a software-oriented synchronous stream cipher with very strong security properties and support for 128-bit keys. Rabbit is part of the European Union’s eSTREAM portfolio of stream ciphers addressing the need for strong and computationally efficient (i.e., fast) ciphers. Extensive cryptanalysis confirms Rabbit’s strength against modern attacks; attacks with complexity lower than an exh...
متن کاملThe Stream Cipher Rabbit
1 This is version 1.1 of the cipher specification as submitted to the eStream project. The only changes in comparison to version 1.0 are some additions to section 7 on computational efficiency and a new appendix A, which describes an 80-bit key setup.
متن کاملThe Rabbit Stream Cipher
The stream cipher Rabbit was first presented at FSE 2003 [5], and no attacks against it have been published until now. With a measured encryption/decryption speed of 3.7 clock cycles per byte on a Pentium III processor, Rabbit does also provide very high performance. Thus, the Rabbit design is currently submitted to the Ecrypt call for stream cipher primitives. This paper gives a concise descri...
متن کاملHardware results for selected stream cipher candidates
This paper presents hardware implementation and performance metrics for the candidate stream ciphers in the Phase II Hardware Focus. Quantitative consideration is also given to all candidate ciphers as to whether any should be added to the Hardware Focus set. In this treatment, only the submissions without licensing restrictions have been considered. The results are presented in tabular and gra...
متن کاملHardware Accelerator for Stream Cipher Spritz
RC4, the dominant stream cipher in e-commerce and communication protocols such as, WEP, TLS, is being considered for replacement due to the series of vulnerabilities that have been pointed out in recent past. After a thorough analysis of the possible weaknesses, Spritz, a new stream cipher is proposed to that effect by the author of RC4. The design of Spritz is based on Cryptographic Sponge con...
