Abstract

In the next generation mobile telecommunications, any third party that provides wireless data services (e.g., mobile banking) must have its own solution for end-to-end security. Existing mobile security mechanisms are based on public-key cryptosystem. The main concern in a public-key setting is the authenticity of the public key. This issue can be resolved by identity-based (ID-based) cryptography where the public key of a user can be derived from public information that uniquely identifies the user. This paper proposes an efficient ID-based encryption algorithm. We actually implement the ID-based encryption schemes and compare the performance to show the advantage of our approach. Our study indicates that our solution outperforms a previously proposed algorithm by 20 - 35%
