Improved Key Agreement Based Kerberos Protocol for M-Health Security

Security Proof for the Improved Ryu-Yoon-Yoo Identity-Based Key Agreement Protocol

Key agreement protocols are essential for secure communications in open and distributed environments. The protocol design is, however, extremely error-prone as evidenced by the iterative process of fixing discovered attacks on published protocols. We revisit an efficient identity-based (ID-based) key agreement protocol due to Ryu, Yoon and Yoo. The protocol is highly efficient and suitable for ...

Provably secure and efficient identity-based key agreement protocol for independent PKGs using ECC

Key agreement protocols are essential for secure communications in open and distributed environments. Recently, identity-based key agreement protocols have been increasingly researched because of the simplicity of public key management. The basic idea behind an identity-based cryptosystem is that a public key is the identity (an arbitrary string) of a user, and the corresponding private key is ...

Improved ID Based Key Agreement Protocol Using Timestamp

ID-based encryption (or identity-based encryption (IBE)) is an important primitive of ID-based cryptography. As such it is a type of public-key encryption in which the public key of a user is some unique information about the identity of the user (e.g. a user's email address). This can use the text-value of the name or domain name as a key or the physical IP address it translates to. Authentica...

An Improved Authenticated Multiple-key Agreement Protocol

A Survey of Kerberos V and Public-Key Kerberos Security

Kerberos was initially developed at MIT as a part of Project Athena and in these days it is widely deployed single sign-on protocol that is developed to authenticate clients to multiple networked services. Furthermore, Cross-realm authentication is a useful and interesting component of Kerberos aimed at enabling secure access to services astride organizational boundaries. Also, Kerberos has con...
