Public Key Cryptosystems Based on Free Partially Commutative Monoids and Groups
At INDOCRYPT 2003 Abisha, Thomas, and Subramanian proposed two public key schemes based on word problems in free partially commutative monoids and groups. We show that both propos...

An efficient undeniable group-oriented signature scheme
Three main methods with favorable security and efficiency can be considered in the design of cryptosystems. These methods are integer factorization systems (of which RSA is the be...

Secret Sharing and Non-Shannon Information Inequalities
The known secret-sharing schemes for most access structures are not efficient; even for a one-bit secret the length of the shares in the schemes is 2O(n) , where n is the number of...
