A flexible and scalable authentication scheme for JPEG2000 image codestreams
JPEG2000 is an emerging standard for still image compression and is becoming the solution of choice for many digital imaging fields and applications. An important aspect of JPEG2...

Signature Schemes Based on the Strong RSA Assumption
We describe and analyze a new digital signature scheme. The new scheme is quite efficient, does not require the the signer to maintain any state, and can be proven secure against ...

How to Strengthen Any Weakly Unforgeable Signature into a Strongly Unforgeable Signature
Standard signature schemes are usually designed only to achieve weak unforgeability – i.e. preventing forgery of signatures on new messages not previously signed. However, most s...

An Approach to Shorten Digital Signature Length
A new method is proposed to design short signature schemes based on difficulty of factorizing a composite number n = qr, where q and r are two large primes. Using the method new d...
