A security scheme for protecting security policies in firewall
Jung-Seuk Lee, Jun‐Cheol Jeon, Kee-Young Yoo · ACM SIGOPS Operating Systems Review · 2004
This paper discusses the problem of protecting security policies and other related information in security mechanisms, such as the filtering policy of a firewall in distributed or ubiquitous environment. Unauthorized disclosure of such information might reveal the fundamental principles and methods for the protection of the whole network. We discuss the problem with typical protecting method using hash functions and we propose a scheme that protects the rule in firewall using cryptographic algorithm.
