摘要： A method for establishing a secure connection between two network devices, such as a source end host and a destination end host, is disclosed. An initiator peer that sends network traffic on behalf of the source end host sends to a responder peer a first description of network traffic that is to be protected. In response, the initiator peer receives a second description of network traffic that is to be protected from the responder peer. The initiator peer then derives a third description of network traffic that is mutually acceptable to both the initiator peer and the responder peer. The third description of the network traffic is based on the first description of network traffic and the second description of the network traffic. The third description of network traffic is derived by finding the largest common subset of proxies from the first and second descriptions of network traffic.

摘要： Techniques are provided for detecting modifications to software instructions. At a computing apparatus configured to execute a software program comprising a plurality of instructions, at least a first check point having a first check value and a second check point having a second check value are assigned within the instructions. At least first and second portions of the instructions are identified. The first portion of the instructions comprises one or more check points other than the first check point. The second portion of the instructions comprises one or more check points other than the second check point. A first hashing operation is performed over the first portion resulting in a first equation and a second hashing operation is performed over the second portion resulting in a second equation. The first check value and the second check value are computed based on the first equation and the second equation.

摘要： A mechanism for providing strong anti-replay protection at a security gateway in a network for protection against an attacker duplicating encrypted packets. The mechanism assigns a unique sequence number to each encrypted packet and a time stamp. A receiving security gateway rejects packets that have a duplicative sequence number or that is too old to protect itself against replay attacks. Each security gateway checks off the sequence numbers as they are received knowing that the sending security gateway assigns sequence numbers in an increasing order. The receiving security gateway remembers the value of the highest sequence number that it has already seen as well as up to N additional sequence numbers. Any packet with a duplicative sequence number is discarded. In addition to the sequence number, each packet also has an associated time stamp that corresponds to an epoch during which it should be received. If the packet is received after the epoch has expired, the packet is rejected.
摘要翻译：一种用于在网络中的安全网关提供强大的反重放保护的机制，用于防止复制加密分组的攻击者。该机制为每个加密的分组和时间戳分配唯一的序列号。接收安全网关拒绝具有重复序列号或太旧的数据包，以保护自身免受重放攻击。每个安全网关检查序列号，因为它们被接收，知道发送安全网关按照递增的顺序分配序列号。接收安全网关记住其已经看到的最高序列号的值以及最多N个附加序列号。任何具有重复序列号的数据包都被丢弃。除了序列号之外，每个分组还具有对应于其应该被接收的时期的相关联的时间戳。如果在时期到期后收到数据包，则数据包被拒绝。

摘要： A block cipher mode of operation implements a block cipher with an arbitrary block length and provides output ciphertext that is always the same size as the input plaintext. The mode can provide the best possible security in systems that cannot allow data expansion, such as disk-block encryption and some network protocols. The mode accepts an additional input, which can be used to protect against attacks that manipulate the ciphertext by rearranging the ciphertext blocks. The universal hash function from Galois/Counter Mode of operation for block ciphers may be used in an embodiment for hardware and software efficiency.
