....by encrypting and encapsulating the original IP packet in the data segment of the new IPSec packet. The encryption algorithm and keys are negotiated and exchanged using the Internet Key Exchange (IKE) protocol (see Section 4.1. 3) All implementations of IPSec are required to support the DES [oS88] and Triple DES [KMS95] cryptographic algorithms, and some implementations additionally support algorithms such as Blowfish. IPSec has a small number of limitations which have implications for its use in VPNs, the most serious being compatibility problems with NAT, ICMP, FTP, IKE, IP ....

....to interface with them, rather than coding our own implementations of the various MAC, encryption, and authentication algorithms. As cryptographic standards and algorithm progress and evolve, this permits us to easily keep apace. Currently, an interface with OpenSSL [27] allows using RC4, DES [13], IDEA [45] and Die Hellman [44] For authentication, in addition to PGP [34] we have a Kerberos [2] interface, though it is out of date. 3.3 Random number generation Cryptographically secure random numbers are vital to any secure system. It is not possible to generate truly random numbers and ....

....old untrusted members will not be able to eavesdrop on the group conversations. 3.2 Cryptographic infrastructure Our design supports the use of a variety of authentication, signature and encryption mechanisms. By default the system uses PGP for authentication, MD5 [15] for signature, and RC4 [16] for encryption. Because these three functionalities are carried out independently any combination of supported authentication, signature, and encryption systems can be used. Other systems, such as Kerberos [17] IDEA [18] and DES [16] have been interfaced with Ensemble at various stages. 3.3 ....

It is not possible to generate truly random numbers and therefore one uses pseudo random number generators. We have plugged in ....

The outer chaining technique is used. In DES EDE3 CBC, an Initialization Vector (IV) is XOR d with the first 64 bit (8 byte) plaintext block (P1) The keyed DES function is iterated three times, an encryption (Ek1) followed by a decryption (Dk2) followed by an encryption (Ek3) and generates ....
