To provide authentication, some researchers utilize one way key chains and delayed disclosure of keys; however, such an approach requires time synchronization and delayed authentication. Another technique uses one-time signature schemes. Unfortunately, such schemes suffer from large key sizes and limited number of uses per key. To cope with these problems, we propose an efficient, one-time signature-based broadcast authentication scheme for wireless sensor networks that reduces storage usage and includes a re-keying mechanism. Keywords: Authentication, re-keying mechanism, hash trees.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786202667982\"\u003e\u003ch3\u003eA Technique Stenography for hiding secret in format and its applications\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786202667982","offer_id":39448923439197,"sku":"9786202667982","price":39.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/5f6769f9-d112-49d8-bb8a-dae6b73d2431.jpg?v=1775712000","url":"https:\/\/shop.autorenwelt.de\/en\/products\/network-security-a-technique-stenography-for-hiding-secret-in-format-and-its-applications-von-tripti-arjariya","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
