Abstract(in English) | Cryptographic communication is essential for the services on the Internet. Cryptographic algorithms which are used in security protocols are reduced in strength because of an enhancement in the computation power or a new method for decryption. It is called the cryptography compromising problem. It is important for the service providers which use cryptographic communications to take care this problem in order to preserve the security and the connectivity. In this paper, we discuss about the cryptography compromising problem from the point of view of the service providers. Based on this discussion, we propose that a method to check cryptographic algorithms in security protocols. We focus on the negotiation between the server and the client to extract the cryptographic algorithms used in the security protocol. In addition, we mention a countermeasure against compromising of cryptosystems in SSL by using this method and a compromising list. |
