Techopedia Explains Shared Secret A shared secret is one of the most important mechanisms in cryptography as it allows secure communication to happen between two or more parties. Without a shared secret among th
The most important principle to keep in mind is that you should never attempt to design your own cryptosystem. The world’s most brilliant cryptographers (including Phil Zimmerman and Ron Rivest) routinely create cryptosystems with serious security flaws in them. In order for a cryptosystem to be...
Encryption is a way to conceal information by altering it so that it appears to be random data. Encryption is essential for security on the Internet. Learning Objectives After reading this article you will be able to: Understand what encryption means ...
SSL, or Secure Sockets Layer, was the original security protocol developed for HTTP. SSL was replaced by TLS, or Transport Layer Security, some time ago. SSL handshakes are now called TLS handshakes, although the "SSL" name is still in wide use. Whitepaper Maximize the power of TLS Get ...
InfoSec is closely related to data security — a subset that specifically protects digitized data stored in systems and databases or transmitted across networks. Both disciplines share three primary objectives: Confidentiality:Ensuring confidential information remains a secret. ...
The root cause for both messages is the same, and is unambiguous: The shared secret on the RADIUS server and the NAS are not the same. However, there can be some confusion because, depending on what information RADIUS receives in the packet header, you w

With DBaaS, users can concentrate on their business priorities and optimize their databases for applications, instead of spending resources on managing and monitoring tasks, high availability, backups, security and compliance, OS and database patching, or network configuration. DBaaS is a...
What does HMAC stand for? The term HMAC is short for Keyed-Hashing for Message Authentication. HMAC is a message authentication code created by running a cryptographic hash function, such as MD5, SHA1, and SHA256, over the data to be authenticated and a shared secret key. HMAC is reference...
SKA is not considered a secure approach to providing network access. This is attributed to the use of conventional unsecured channels to share security keys required for access. However, the authentication process is secured using 64- or 128-bit encryption. This means threat actors cannot gain acc...
