This page is about who I am – a brief introduction. First if all, welcome to my website. I hope you find the contents useful.
By education and experience, I am a hardware design electronics engineer. Nowadays, I design complex Integrated Circuits (IC) and FPGAs, mainly for storage and networking hardware. That job requires proficiency in SystemVerilog and VHDL. Functional verification of designs is also required. It includes the following: UVM, constrained random methodology, assertions, and functional coverage.
Additional skills, such as system architecture design, project, and engineering management round up my background.
Outside the main focus, I maintain a keen interest in software development and Web technologies.
Interests and Activities page lists all my fun activities and personal interests. (Fun is defined as not earning me any money – a situation I hope to remedy.) As the list indicates, my interests are quite eclectic. I have been acquiring them one-by-one over a long time. As a result, they have accumulated into a bunch! Needless to say, I cannot enjoy all of them at the same time. Therefore, they come and go as my life changes direction. Usually one or two are most active at any given moment.
Over the course of my life, I have acquired knowledge of many subjects that other people may find useful. I will share those in my blog posts.
Online threats to email communications are constantly growing. Attacks such as phishing, spoofing, snooping, and intercepting (man-in-the-middle) proliferate and are becoming more sophisticated. An effective way to counter these challenges is to sign emails with digital (cryptographic) signatures. The signature provides:
- Sender verification – the sender is who he/she claims to be
- Message integrity – the message was not altered
- Non-repudiation – the signer cannot afterwards deny signing the message
PGP (Pretty Good Privacy) is a popular implementation of public-key cryptography, which uses pairs of keys: public and private. Despite its deprecating name, the PGP cryptographic algorithms are very strong. Consequently, PGP is a safe tool for securing emails.
