The use of IPsec is pervasive throughout the networking industry. However, many organizations are using IPsec in sub-optimal configurations that result in weaker connection security. Many ...

As discussed above, IPsec delivers data confidentiality services by executing a transform on plain text data. Common ciphers used in the IPsec transform are DES, 3DES, and AES. All of these transforms ...

Security demands focus the need for authentication, encryption, and digital signatures in embedded network devices as more devices are connected to the Internet. Attacks on desktops, servers, and PCs ...

If you are serious about computer/network security, then you must have a solid understanding of authentication methods. Debra Littlejohn Shinder takes a moment to lay out the role authentication plays ...

The challenge of accelerating cryptographic functions, such as encryption and decryption, at high data rates is no longer limited to speeding algorithm processing. Establishing and managing secure ...

As an independent consultant, I am often asked to be a ‘fresh set of eyes’ and perform a network assessment. This sometimes involves an examination of an IPsec VPN. During discussions around an IPsec ...

IPv6 is starting to show up in around the Internet. Adoption is slow, but with the magic number of 4 billion- plus IPv4 addresses about to be reached, IPv6 will see a much faster pace of adoption as ...

I’ve been using a wireless network for a few months. I don’t know much about (Wi-Fi) encryption and security, but I would like to get a better understanding so I can respond appropriately in certain ...

In today’s connected world, where data is a crucial asset in SoCs, Part V of our series explores how to protect and encrypt data, whether at rest, in transit, or in use building on our earlier blog ...
