Eurasian water shrew [1] Conservation status Least Concern  (IUCN 3.1) [2] Scientific classification Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Eulipotyphla Family: Soricidae Genus: Neomys Species: N. fodiens Binomial name Neomys fodiens (Pennant, 1771) Eurasian water shrew range The Eurasian water shrew ( Neomys fodiens ), known in the United Kingdom as the water shrew , is a relatively large shrew, up to 10 cm (4 in) long, with a tail up to three-quarters as long again. It has short, dark fur, often with a few white tufts, a white belly, and a few stiff hairs around the feet and tail. It lives close to fresh water, hunting aquatic prey in the water and nearby. Its fur traps bubbles of air in the water which greatly aids its buoyancy, but requires it to anchor itself to remain underwater for more than the briefest of dives. Like many shrews, the water shrew has venomous saliva, making it one of the few venomous mammals, although it is not able to puncture the skin of

RSA PSS security advantage

Clash Royale CLAN TAG #URR8PPP up vote 5 down vote favorite 2 To my humble opinion, please correct me if I'm wrong, RSA-PSS (PKCS#1 ver 2.1) advantage over RSA as described in PKCS#1 ver. 1.5 is in its security proofs. Does this proof and the advantage is still there even if the "salt" in the RSA-PSS scheme is constant over all messages, or it conditioned in generating a random salt each and every signature? That is, does the security proof of RSA-PSS assumes random salt over messages? rsa signature salt digital share | improve this question asked Dec 3 at 11:20 Evgeni Vaknin 375 1 10 Related to Why use randomness in digital signature algorithms?. – fgrieu Dec 3 at 11:46 add a comment  |  up vote 5 down vote favorite 2 To my humble opinion, please correct me if I'm wrong, RSA-PSS (PKCS#1 ver 2.1) advantage over RSA as described in PKCS#1 ver. 1.5 is in its security proofs.
