An Asymmetric Cryptography Secure Channel Protocol for Smart Cards

Smart eard seeure ehannel protocols based on publie key eryptography are not widely utilised mainly due to proeessing overheads introdueed in the underlying smart eard microproeessors and the complexities introdueed by the operation of a PKI infrastructure, In this paper we analyse the signifieanee of publie key seeure ehannel protoeols in multi applieation smart eards. We believe that multi applieation smart eard teehnology (e.g. the GlobaIPlatform smart eard specifieation) should benefit more from the advantages of publie key eryptography specifically for the initiation and maintenance of aseeure ehannel. This paper introduees a publie key based eryptographic protocol for seeure entity authentication, data integrity and data confidentiality. The proposed seeure channel protocol uses a combination of publie key, seeret key and the main idea behind the Diffie-Hellmann key establishment protoeols in order to achieve the desired goals.
