UA | Attributes’ name | Description |
---|---|---|
UA1 | Authentication between MANET’s user and intermediate node | Since end-users may request for services or information, MANET intermediate nodes provide services/information. Therefore, mutual authentication between end-users and intermediate node becomes essential |
UA2 | Authentication between MANET’s end users | Authentication should also be done between two end-users, i.e. the sender and receiver in order to avoid repudiation |
UA3 | User’s amicable registration phase | Registration phase from registration authority should be amicably and not put any kind of burden on users like remembering to the random number, etc., until not received the smart card |
UA4 | Password change facility: user friendly and secure | Whenever the user needs to change the password, it should be friendly without interrupting registration authority. Keeping the same password for a long time is not suggested due to vulnerability towards password guessing. Moreover, the password changing mechanism must be secure in order to avoid false updating from the adversary |
UA5 | Creation of session key | In order to provide good mutual authentication between two authorized communication parties, to keep confidentiality of messages and to provide a secure communication atmosphere after the end of the session generation of session key becomes an important concern |
