Cryptocurrency Wallet Security
As the popularity of cryptocurrency trading explodes, one of the biggest risk factors for existing and potential investors continues to be the large scale hacks of exchanges and digital wallets. Digital wallets are well-known across legacy applications such as e-payment and PKI, with cryptocurrencies now added to the list. Security is very important for all of these applications, but perhaps most for cryptocurrencies, because transactions are irrevocable when they’re used in conjunction with blockchain schemes.

Meltdown and Spectre – divide and conquer
Security experts recently revealed two computer flaws called Meltdown and Spectre, serious vulnerabilities that threaten data by targeting modern microprocessors. This blog post discusses cryptographic protection called Multi-Party Computation (MPC), a way of mitigating the attack vectors by distributing vulnerable data onto different servers, a so-called "divide and conquer" strategy.

If I had a KMaaS in 2013
This is a story about how I came to wish for a pure-cloud Key Management System (KMS), delivered in the form of a SaaS offering, for the strong encryption of unstructured data. In other words, a true Key Management as a Service (KMaaS) that could be decoupled entirely from expensive conventional Hardware Security Module (HSM) appliances, deliver cryptographic security (rather than password or trust based), and yet, scale at cloud economics.

Lack of Trust in Big Brother
Everywhere I turn these days, I find plenty of bewildering bills and proposals related to privacy, security, and encryption from congressmen, senators, assemblymen and politicians of various colors who are in the business of introducing legislation in the U.S., EU, and other countries. Yet, I had to stand up and take notice when the United States Supreme Court made an update to a ruling (Rule 41) in late April that had the effect of allowing U.S. law enforcement agencies such as the FBI to expand their ability and scope when it comes to hacking into computers regardless of their location.
