2. Key management in wireless sensor networks

Key management is an essential function in any cryptographic system to ensure security services such as confidentiality, authentication, non-repudiation, etc. This aspect covers key generation, granting or transporting keys in a secure manner, their storage and verification, renewal and revocation. It covers key generation, secure key granting or transport, key storage and verification, key renewal and key revocation.
