Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions. … See more Before the mid-1970s, all cipher systems used symmetric key algorithms, in which the same cryptographic key is used with the underlying algorithm by both the sender and the recipient, who must both keep it secret. Of … See more The most obvious application of a public key encryption system is for encrypting communication to provide confidentiality – a message that a sender encrypts using the recipient's public … See more Examples of well-regarded asymmetric key techniques for varied purposes include: • Diffie–Hellman key exchange protocol • DSS (Digital Signature Standard), which incorporates the Digital Signature Algorithm See more • Books on cryptography • GNU Privacy Guard • Identity-based encryption (IBE) • Key escrow See more As with all security-related systems, it is important to identify potential weaknesses. Aside from poor choice of an asymmetric key algorithm (there are few which are widely regarded as satisfactory) or too short a key length, the chief security risk is that the … See more During the early history of cryptography, two parties would rely upon a key that they would exchange by means of a secure, but non-cryptographic, method such as a face-to-face meeting, or a … See more • Oral history interview with Martin Hellman, Charles Babbage Institute, University of Minnesota.
