SuperSocket 1.4 SP2 Release

SuperSocket is a light weight, cross platform and extensible socket application framework. You can use it to build a server side socket application (like FTP server, SMTP/POP3/IMAP4 server, SIP server, SNMP server, etc) easily without thinking about how to use socket, how to maintain the socket connections and how socket works(synchronize/asynchronize).

It is a pure C# project which is designed to be extended, so it is easy to be integrated to your existing system. If your systems (like forum/CRM/MIS/HRM/ERP) are developed in .NET language, you must be able to use SuperSocket to build your socket application as a part of your current system perfectly.

I know there are two famous NIO open source frameworks named “MINA” and “Netty” in Java World which are used widely by developers. If you want to look for a .NET portion of MINA or Netty, I suggest you trySuperSocket, although SuperSocket is not strong like MINA and Netty but it is very simple and you can use it easily.

Features:

  • Very easy to use. You can create a robust socket server only by several classes
  • Support Sync and Async communication modes. You can change your socket server running mode by only changing configuration wihtout any code changes
  • Support custom protocol, no matter your protocol is a command line protocol or a binary one. Another open source project SuperWebSocket is built upon SuperSocket and take advantage of this custom protocol feature of it.
  • Support SSL/TLS encryption automatically
  • Support multiple socket server instances. You can define many socket servers on different ports in configuration, SuperSocket can run those servers in the same application/service
  • SuperSocket can run as console application and windows service. It provide a bat file to installSuperSocket as a windows service.
  • Flexible logging strategy which can log most of socket activities
  • Also support UDP socket
  • Support IPv6
  • Support Windows Azure
  • Support running in Unix system (by Mono 2.10 or above version)
  • Built-in socket policy server for Flash and Silverlight clients which you can use directly

Security Analysis of a PUF based RFID Authentication Protocol

Abstract: In this paper we consider the security of a PUF based RFID Authentication protocol which has been recently proposed by Bassil et al. The designers have claimed that their protocol offers immunity against a broad range of attacks while it provides excellent performance. However, we prove in contrary to its designers claim that this protocol does not provide any security. We present an efficient secret disclosure attack which retrieves all secret parameters of the protocol. Given those secret parameters, it would be trivial to apply any other attack in the context on the protocol. However, to highlight other weaknesses of the protocol we present extra reader traceability, impersonation and desynchronization attacks that do not require disclosing the secret parameters necessarily. Success probability of all mentioned attacks is almost “1” while the complexity is at most two runs of protocol.
