Cryptography and Computer Communications Security. Extending the Human Security Perimeter through a Web of Trust
This work modifies Shamir’s algorithm by sharing a random key that is used to lock up the secret data; as against sharing the data itself. This is significant in cloud computing, especially with homomorphic encryption. Using web design, the resultant scheme practically globalises secret sharing …

A modulation-doped field-effect transistor-based optoelectronic integrated circuit receiver for optical interconnects
The success of optical interconnects for computer communications depends critically on the development of a viable monolithic optoelectronic integrated circuit (OEIC) technology. A key component of any lightwave communication system is the optical receiver/preamplifier which converts the low-level …

Product cipher negotiation with on-line evaluation for private communication over computer networks
A method is proposed to offer privacy in computer communications, using symmetric product block ciphers. The security protocol involved a cipher negotiation stage, in which two communicating parties select privately a cipher from a public cipher space. The cipher negotiation process includes an …

Visual Correlation of Network Traffic and Host Processes for Computer Security
Much computer communications activity is invisible to the user, happening without explicit permission. When system administrators investigate network communications activities, they have difficulty tracing them back to the processes that cause them. The strictly layered TCP/IP networking model that …

When does the conduct of an employer infringe on an employee's constitutional right to privacy when intercepting or monitoring electronic communications?
The Regulation of Interception of Communications and Provision of Communication Related Information Act 70 of 2002 (RICA) that regulates the monitoring of electronic communications has not yet been tested by our courts. This paper explores the likelihood of an infringement of an employee's right to …
