SEHadoop Block Token
We designed SEHadoop Block Token to fix the overloaded
authentication key vulnerability. SEHadoop Block Token uses
secret keys to conduct for an authentication, but these keys
are different for each Data Node. SEHadoop Block Token uses
AES algorithm to encrypt plain-text of the token’s content, thus
SEHadoop Block Token’s content remains protected during
transfer from a Name Node to a Data Node. The SEHadoop
Block Token’s generation formats are as follows:
