• What is Cryptography?

    Cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Various aspects of information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography. Modern CRYPTOGRAPHY Prior to the modern age, cryptography was effectively synonymous with encryption, the conversion of information from a readable state to apparent nonsense. Modern cryptography is heavily based on mathematical theory and computer science. Cryptographic algorithms are designed around computational hardness assumptions, making the algorithms hard for adversaries to break. There exist information-theoretically secure schemes that probably cannot be broken even with unlimited computing power.

  • Blockchain – what is it and where is it used?

    Blockchain - in simple

    Blockchain – in simple terms, is a clearly designed database in which the requirements of building chains of operations are met. It can contain not only information about financial transactions but also a system that can be used as a long-lasting archive for information about all transactions performed. How blockchain works The work of the blockchain system can be represented on the basis of a bank cell that is accessible to all users, i.e. everyone can see, but only those who have access to it, or the one to whom the cell owner has granted this access can use. Structure and safety The blockchain structure is based on interrelated transactions and reliability of information, while there is no possibility to withdraw any block of information because all the others change, this eliminates the possibility of hacking theft and fraud.
