Algorithm Name: NLSv2
Note that only the encryption algorithm of NLSv2 will be considered in the eSTREAM Phase 3. The authentication part of NLSv2 will not be considered in Phase 3.
Submitters : Gregory Rose, Philip Hawkes, Michael Paddon
and Miriam Wiggers de Vries
Type of Algorithm : Synchronous Stream Cipher
Proposed Environment : Profile 1A (SW with authentication)
and 2A (HW with authentication)
Intellectual Property : Free for any use. statements
The original NLSv2 article is available here. On April 13 2007 an error in the specifications of the Loadkey algorithm was corrected. The source code remains unchanged.
