Motivated by the conflict between authenticity and privacy in the digital signature, the notion of limited verifier signature was introduced [1]. The signature can be verified by a...
Group signature schemes are cryptographic systems that provide revocable anonymity for signers. We propose a group signature scheme with constant-size public key and signature leng...
The issue of certificate masquerading against the SSL protocol is pointed out in [4]. In [4], various forms of server certificate masquerading are identified. It should also be no...
The cryptosystem recently proposed by Cramer and Shoup [CS98] is a practical public key cryptosystem that is secure against adaptive chosen ciphertext attack provided the Decision...
Image feature detection is a fundamental issue in computer vision. SIFT[1] and SURF[2] are very effective in scale-space feature detection, but their stabilities are not good enou...
