Illustrate about TinySec Protocol
TinySec is implemented on the link layer and addresses security requirements of the resource staffed nodes in the WSN based on the link layer cryptography. The link layer protocol security requirements include message integrity, access control, and message confidentiality. The IPSec, SSL/TLS protocols cannot be applied on resource staffed WSN nodes because they are resource intensive. TinySec provides security solutions based on authentication only (TinySec-Auth), and the authenticated encryption (TinySec-AE) security options. TinySec uses "MAC to authenticate data payload which has been encrypted" and "MAC computations done on the packet data".
