Fast and Secure Protocol
The Fast and Secure Protocol - also called FASP - is a data transfer protocol. FASP is a network-optimized network protocol developed by Aspera Inc., California .
Similar to the connectionless UDP protocol, FASP does not expect any feedback on every packet sent. Only the packets marked as really lost must be requested again by the recipient. As a result, due to high latency and packet losses, it does not suffer as much loss of throughput as the TCP protocol [1].
Big companies like IBM [2] and others [3] use the protocol in different areas. Amazon also wants to use the protocol for uploading data centers [4] . Security
The FASP protocol has built-in security mechanisms that do not affect the transmission speed. The encryption algorithms used are based exclusively on open standards. Before the transfer, SSH is used for key exchange for authentication. These randomly generated, one-way keys are discarded at the end of the transmission.
The data is encrypted or decrypted immediately before sending and receiving with the AES-128 . To counteract attacks by monitoring the encrypted information during long transfers, the AES is operated in cipher feedback mode with a secret initialization vector for each block. In addition, an integrity check of each data block takes place, in which case, for example, a man-in-the-middle attack would be noticed.
