FIT5167 – Natural Computation Week 9

Natural computation’s 9th week saw an introduction to associative memory networks.   Initialization of an Bi-Directional Associative memory network involves establishing a weight matrix using input and output pairs: It seems much easier to write a simple script which demonstrates understanding of the weight initialization and memory recall algorithms. Hopefully I can do that this week. The major question that comes to mind after this lecture was why these networks would be used.. Read More

FIT5044 – Network Security Week 9

Week 9 continued from IPsec into security at the transport layer, specifically SSL. Unsurprisingly, given that SSL uses public key cryptology is used at least in the initial stages of all SSL connection, distribution and authentication of public keys was the first issue raised. The use of certificate authorities providing signed keys is the current solution. Similarly to IPsec, authentication, integrity and confidentiality are the goals of SSL. With such a wide number of computers using SSL, there.. Read More
