Abstract

This paper presents the Split and Merge method, an

approach to provide secure communication over the

Internet using software agents. Instead of relying

The method is detailed in the paper and the current

The solutions found to deal with error detection and

research directions are presented.

ciphering functions.

Regarding key secrecy, methods have been designed

ranging from the Diffie Hellman key agreement protocol

[1] to the public key cryptography of Rivest, Shamir and

Adleman [2].

For the second principle, the focus has been put in the

slight decline has been noticed on the increase of the

density of the circuits, mainly due to physical limitations.
