ESSTCP: Enhanced Spread-Spectrum TCP

Having stealth and lightweight authentication methods is empowering network administrators to shelter critical services from adversaries. Spread-spectrum TCP (SSTCP) is one of these methods by which the client sends an authentic sequence of SYN packets to the server for authentication. Since SSTCP have some certain drawbacks and security flaws, we propose an enhanced version of SSTCP (ESSTCP) which modifies the original algorithm to reduce the computational cost and cover its vulnerabilities from denial of service and replay attacks. Some performance problems like time synchronization are also resolved. We finally try to extend the functionality of this method for different applications and numbers of users by which ESSTCP can be performed as a secure remote procedure call (RPC).
