Trends in Security Information
The HSD Trendmonitor is designed to provide access to relevant content on various subjects in the safety and security domain, to identify relevant developments and to connect knowledge and organisations. The safety and security domain encompasses a vast number of subjects. Four relevant taxonomies (type of threat or opportunity, victim, source of threat and domain of application) have been constructed in order to visualize all of these subjects. The taxonomies and related category descriptions have been carefully composed according to other taxonomies, European and international standards and our own expertise.
In order to identify safety and security related trends, relevant reports and HSD news articles are continuously scanned, analysed and classified by hand according to the four taxonomies. This results in a wide array of observations, which we call ‘Trend Snippets’. Multiple Trend Snippets combined can provide insights into safety and security trends. The size of the circles shows the relative weight of the topic, the filters can be used to further select the most relevant content for you. If you have an addition, question or remark, drop us a line at info@securitydelta.nl.

Encryption is the process of disguising information as “ciphertext”, or as unintelligible data to an unauthorized person. Decryption is the opposite process of converting data back into its original, intelligible, format. Encryption is thus aimed at ensuring the confidentiality of data. Encryption requires a ‘key’, generally known to the transmitter and recipient of the data to control the way in which the data is made unreadable and subsequently readable. Symmetric encryption requires the key to be the same for the transmitter and recipient. Asymmetric encryption has a pair of keys; one for encryption and one for decryption. Computers use algorithms to encrypt data. Official standards of encryption and accessory algorithms, approved by standardisation authorities, exist for both symmetric and asymmetric encryption.
Encryption is an important part of all Information and Communication Technology (ICT). Examples of its use are the SSL/TLS protocols that provide secure access to websites (and show the ‘lock’ symbol in the URL bar of a web browser), encrypted e-mails, ‘end-to-end encryption’ messaging apps and digital signatures. Encryption can be ‘cracked’, given enough time and computing power. The higher the standard of encryption applied, the more time and money it costs to break it open. A threat to current day encryption is the advancements in quantum computing, which might make it possible to crack high standards encryption. Post-quantum encryption standards are under development.
Related Keywords: authentication, confidentiality, cryptography, decipher, integrity, availability, security, privacy, encoding information, ciphering, pseudo-random encryption, Public Key Infrastructure (PKI), RSA, Pretty Good Privacy (PGP), digital certificate, HTTPS, homomorphic encryption, secure multi-party computation, quantum encryption.
