Can public key be used for authentication if the asymmetric relation in terms of complexity in computing keys is reversed?
Public-key cryptography fundamentally relies on the asymmetric nature of key pairs for secure communication, encryption, and authentication. In this system, each participant possesses a pair of keys: a public key, which is openly distributed, and a private key, which is kept confidential. The security of this system hinges on the computational difficulty of deriving the
What is the exponentiation function in the RSA cipher?
The RSA (Rivest-Shamir-Adleman) cryptosystem is a cornerstone of public-key cryptography, which is widely used for securing sensitive data transmission. One of the critical elements of the RSA algorithm is the exponentiation function, which plays a pivotal role in both the encryption and decryption processes. This function involves raising a number to a power, and then

Can a private key be computed from public key?
Public-key cryptography, also known as asymmetric cryptography, is a fundamental concept in the field of cybersecurity. It involves the use of two distinct but mathematically related keys: a public key, which can be disseminated widely, and a private key, which must be kept confidential by the owner. The security of public-key cryptographic systems relies heavily
