hash functions. A weakness in SESAME is that, similar to
Kerberos, it is subject to password guessing.

(ISO/OSI) Layers and Characteristics Standard model for network communications enables dissimilar networks to communicate, Defines 7 protocol layers (a.k.a. protocol stack) Each layer on one workstation communicates with its respective layer on another workstation using protocols (i.e. agreed-upon communication formats) "Mapping" each protocol to the model is useful for comparing protocols.
