Security Analysis of Digital Signature Scheme with Message Recovery using Self-Certified Public Keys
Mahshid Sadeghpour · Global Society of Scientific Research and Researchers - International Journal of Computer · 2017
Tseng and his colleagues have proposed two variants of authenticated encryption scheme using self-certified public keys.Their schemes have two fundamental properties.Only the intended receiver can recover the message while verifying the signature, and each user can use his own private key independently without system authority learning about it.This paper presents man-in-the-middle attacks to both Tseng and his colleagues authenticated encryption variants.It will be shown that these schemes are not secure against this attack.
