Cryptographic Protocol

Cryptographic protocols are sets of rules governing secure communication and computation, aiming to protect data confidentiality, integrity, and authenticity. Current research emphasizes developing faster and more secure protocols, particularly focusing on techniques like oblivious transfer for unconditionally secure communication and variational quantum attacks to assess the vulnerability of existing protocols to quantum computing. This field is crucial for securing sensitive data in various applications, from online transactions to machine learning, and advancements are driving improvements in both theoretical security and practical efficiency.
