  1. NTRU Cipher Suites for TLS<draft-ietf-tls-ntru-00.txt> August 8, 2001 Ari Singer Principal Engineer, NTRU

  2. Purpose of this Draft – Why More Cipher Suites? • Define the use of NTRU and NSS public-key algorithms in TLS • Provide computationally efficient key exchange in TLS for wireless and constrained devices • Provide efficient client authentication in key exchange • Specify TLS cipher suites that can be used on memory-constrained devices • Specify TLS cipher suites that are scalable on the server side with a large population of clients

  3. Overview of the Document • Key exchange algorithms using NTRU certificates signed by NSS or RSA • Specification of cipher suites using NTRU/NSS with SHA-1 hash algorithm and RC4, 3DES and AES symmetric encryption algorithms • Support for multiple key strength key exchange – change from current practice • Published July 3, 2001 – available on IETF web site

  4. Topics for Future Discussion • Draft including NTRU and NSS certificate formats and encoding being presented to PKIX WG (draft-ietf-pkix-pkalgs-supp-00.txt) • Do we want to add support for multiple hash strengths? • Since NTRU key generation is so fast, do we want to add cipher suites with perfect forward secrecy?
