Abstract: A secure session of communication between two entities in a network is disclosed. Using client-server terminology, a client sends a connection-request to a server that authenticates the connection-request and transmits a session-request to the client in response. The client reverse-authenticates the session-request and then passively waits to receive a tunnel-request transmitted by the server. The tunnel-request sets up one or more overlapping tunnels between the client and the server to support the desired communications. Each of the tunnels exists only for a specified time and is replaced by another tunnel that is set up after a selected time delay after the start of a previous tunnel.

Abstract translation: 公开了网络中两个实体之间的安全通信会话。 使用客户端 - 服务器术语，客户端向认证连接请求的服务器发送连接请求，并将响应中的会话请求发送给客户端。 客户端反向验证会话请求，然后被动地等待接收服务器发送的隧道请求。 隧道请求在客户端和服务器之间建立一个或多个重叠的隧道，以支持所需的通信。 每个隧道只存在一段指定的时间，并被另一个在之前的隧道开始之后选定的时间延迟之后建立的隧道所替代。

Abstract: A coprocessor includes a calculation unit for executing at least one command, and a securization device. The securization device includes an error detection circuit for monitoring the execution of the command so as to detect any execution error, putting the coprocessor into an error mode by default as soon as the execution of the command begins, and lifting the error mode at the end of the execution of the command if no error has been detected, an event detection circuit for monitoring the appearance of at least one event to be detected, and a masking circuit for masking the error mode while the event to be detected does not happen, and declaring the error mode to the outside of the coprocessor if the event to be detected happens while the coprocessor is in the error mode. Application in particular but not exclusively to coprocessors embedded in integrated circuits for smart cards.

Abstract: Self-modifying software code comprising a number of modules that each may be modified to be in a plurality of states during execution. In order to verify the integrity of such code, the different states of the code are calculated. For each state a checksum, e.g. a hash value, is generated for at least part of the code. During execution the state of the code is changed, modifying a module, and an integrity check is performed using the checksum for the state of the code. The checksum may be stored in a look-up table or it may be embedded in the integrity verification function. A state variable indicating the state of the modules may be used to look-up the checksum in the table. Possible states of a module is encrypted and decrypted. Also provided is an apparatus for generating protected software code.
