TLDA: An Efficient Two-Layered Data Authentication Mechanism for Content-Centric Networking

Table 2

Theoretical computational overhead and communication overhead comparison. (We assume that a content consists of segments and we apply MHT of size for both mechanisms. symbol denotes the output size of corresponding operation result.)
