Multi-layer security analysis and experimentation of high speed protocol data transfer for GRID. (1st January 2012) - Bernardo, Danilo Valeros
GRID computing infrastructures and applications coordinate uncontrolled and decentralised resources; using new fast data transfer protocols deliver and provide high data transmission that can meet high performance computing requirements of users, institutions, and industries. For such environments standard transport protocols such as TCP and UDP are not always sufficient given their fixed set of properties and limited flexibility. We analyse a new high-speed UDT (UDP-Data Transfer), a protocol considered to have addressed the limitation issues of TCP and UDP. However, this protocol was designed without a well-thought-out security. We surveyed and conducted experiments on existing security mechanisms to determine their viability to secure UDT. The results of the experiments provide important dimensions to our aim of developing comprehensive security architecture for UDT in the future.
