クローンデバイスを識別するために動的な信用証明を使用するシステム及び方法
Document Type and Number:
Japanese Patent JP2008521348
Kind Code:
A
Abstract:
A system and method for providing secure communications between client communication devices and servers. A server generates a random offset. The server alters a server communication device dynamic credential by applying the random offset to the server communication device dynamic credential. The server stores the server communication device dynamic credential. The server sends, via a network, a signal including the random offset. The server receives, via a network, a signal including a dynamic credential. The server determines a difference between the server communication device dynamic credential and the received dynamic credential. In addition, the server detects a presence of a cloned communications device based on the difference.
