- The need to find solutions to two significant problems served as inspiration for the development of public key cryptography, the first of which was the problem of key distribution. Explain the process of key distribution in a nutshell by providing an example of how it might be carried out.Using asymmetric encryption methods, such as those found in public-key cryptography, is a prudent move that should be taken. The use of public keys within the realm of cryptography is proof of this fact.A government organization decides that in order to protect the communications it has with its international partners, encryption is necessary. In a discussion with its equivalents, it is decided to develop a proprietary cryptographic algorithm for the following reasons: Is this decision supported by any evidence. What dangers are being exposed?
- A government department decides it needs to use encryption to protect communication between itself and its international counterparts. At a meeting with its counterparts, it is decided to develop a proprietary cryptographic algorithm for this purpose. Is this decision justifiable? What risks are being taken?The development of public key cryptography was motivated by the requirement to find solutions to two fundamental problems, the first of which is key delivery. Give a concise illustration of how the distribution of keys can be carried out by using an example as a guide.Discuss the concept of modular exponentiation in public-key cryptography and its role in secure communication. Provide an example of its application in an encryption algorithm.
- Public key cryptography was developed to address two fundamental issues, the first of which is key delivery. Provide a quick example of how key distribution may be carried out.Public-key cryptography, or another kind of asymmetric encryption, is strongly suggested. Proof of this may be seen in the use of public keys in cryptography.The usage of public-key cryptography as well as other forms of asymmetric encryption should be used for security purposes. The use of public keys within the realm of cryptography is proof of this fact.
