此时发现流量并未解密,后测试发现密钥前需添加0x表示16进制: 还需在编辑—首选项里设置Protocols,选择ESP协议,勾选 Attempt to detect/decode encrypted ESP payloads,点击OK: 此时解密成功,可以看到内层的ICMP流量: 上面的密钥都是16进制,下面来测试下ESP协议的认证密钥和加密密钥以字符串方式配置是否可以解密。 首先...
IPSec uses two security protocols: Authentication Header (AH) protocol and Encapsulating Security Payload (ESP). Key exchange and SA establishment in IPSec is implemented by the IKE protocol, which simplifies use and management of IPSec. IPSec Security Protocol ...
您可以看到入站和出站构建的两个 Encapsulating Security Payload (ESP) SA。由于没有 AH SA,因此未使用身份验证报头 (AH)。下面是show crypto ipsec sa命令的一个输出示例。interface: FastEthernet0 Crypto map tag: test, local addr. 10.1.0.1 local ident (addr/mask/prot/port): (10.1.0.0/255.255....
緊接AH前面的IPv4或IPv6報頭在其Next Header(或Protocol)欄位中包含值51。 ESP(請參閱RFC 1827 ) ESP可以出現在IP報頭之後和最終傳輸層協定之前。Internet編號分配機構已將協定編號50分配給ESP。ESP報頭前面的報頭始終在其Next Header(IPv6)或Protocol(IPv4)欄位中包含值50。ESP由未加密報頭以及加密資料組...
· Security protocols (AH, ESP, or both). · Encapsulation mode (transport mode or tunnel mode). · Authentication algorithm (HMAC-MD5 or HMAC-SHA1). · Encryption algorithm (DES, 3DES, or AES). · Shared keys and their lifetimes. An SA is unidirectional. At least two SAs are needed ...

The IPSec protocols include - AH, ESP, IKE, ISAKMP/Oakley, and transforms. In order to understand, implement, and use IPSec, it is necessary to understand the relationship among these components. The IPSec roadmap defines how various components of IPSec interact with each other. This is shown...
The physical link's integrity depends on the underlying security protocols. If you set up the security associations securely, then you can trust the tunnel. Packets that exit the tunnel must have originated from the peer that was specified in the tunnel destination. If this trust exists, you ...
