Teaching HW/SW Co-Design With a Public Key Cryptography Application

Teaching Public-Key Cryptography in School

These days, public-key cryptography is indispensable to ensure both confidentiality and authenticity in numerous applications which comprise securely communicating via mobile phone or email or digitally signing documents. For all public-key systems, such as RSA, mathematically challenging and technically involved methods are employed which are often above the level of secondary school students ...

Cryptography. key exchange, public key

General cryptographic schemes are presented where keys can be one-time or ephemeral. Processes for key exchange are derived. Public key cryptographic schemes based on the new systems are established. Authentication and signature schemes are easy to implement. The schemes may be integrated with error-correcting coding schemes so that encryption/coding and decryption/decoding may be done simultan...

Public Key Cryptography

2 Public-key Cryptography

Secure transmission of private information is a crucial issue in today’s highly computerized world. Cryptographic algorithms are used to provide privacy of message transmission and to certify authenticity of sender and/or receiver of a message and message integrity as well as undeniability of transmitted messages (Menezes et al., 1996). The message that is sent by the sender is called the plain...

Certificateless Public Key Cryptography

This paper introduces the concept of certificateless public key cryptography (CL-PKC).In contrast to traditional public key cryptographic systems, CL-PKC does not require theuse of certificates to guarantee the authenticity of public keys. It does rely on the useof a trusted third party (TTP) who is in possession of a master key. In these respects,CL-PKC is similar to identity-b...
