A similar technique has been proposed in 2002 by Shen and Chen, but their scheme suffers large computational overhead and security weakness. We show that our scheme is secure and efficient in comparisons to the Shen and Chen's scheme.<\/jats:p>","DOI":"10.1145\/1044552.1044556","type":"journal-article","created":{"date-parts":[[2005,11,7]],"date-time":"2005-11-07T19:28:32Z","timestamp":1131391712000},"page":"40-47","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":37,"title":["Hierarchical key management scheme using polynomial interpolation"],"prefix":"10.1145","volume":"39","author":[{"given":"Manik Lal","family":"Das","sequence":"first","affiliation":[{"name":"Research in Banking Technology, Castle Hills, Masab Tank, Hyderabad, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ashutosh","family":"Saxena","sequence":"additional","affiliation":[{"name":"Research in Banking Technology, Castle Hills, Masab Tank, Hyderabad, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ved P.","family":"Gulati","sequence":"additional","affiliation":[{"name":"Research in Banking Technology, Castle Hills, Masab Tank, Hyderabad, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deepak B.","family":"Phatak","sequence":"additional","affiliation":[{"name":"Indian Institute of Technology-Bombay, Mumbai, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2005,1]]},"reference":[{"key":"e_1_2_1_1_1","volume-title":"Secure Computer Systems-Unified Exposition and Multics Interpretation.
