L'Ing. Mirko TEDALDI della Cryptonet tiene un seminario dal titolo:
"Wireless and Security: VPN on GSM/GPRS Wireless PKI Wireless LAN"
Abstract:
The widespread use of public networks, such as the Internet, for the exchange of sensitive data, like legally valid documents and business transactions, has been causing a growing interest for information security technologies in order to protect and secure any kind of electronic data. The most famous approach is based upon digital signatures and public-key certificates to guarantee data integrity, authentication and non-repudiation. The required infrastructure to give these security services is called PKI (Public Key Infrastracture).
In addition to this issue, another security requirements is rising: securing the network layer due to the intrinsic IP vulnerabilities (spoofing, sniffing, session highjacking, etc…). For this reason, many companies decide to set up a Virtual Private Network. A VPN is a secure private network built on unsecured public networks as carriers. VPNs use the IPSec protocol suite in order to provide the capability of building secure network within the context of larger, unsecured public IP networks such as the Internet. Users of the secure VPN may use their network as though it were a perfectly secure, isolated LAN, even though it is physically directly connected to unsecured public networks. Moreover, companies and individuals are increasingly using wireless technology for important communications they want to keep private, such as mobile e-commerce transactions, e-mail, and corporate data transmissions.
At the same time, as wireless platforms mature, grow in popularity, and store
valuable information, hackers are stepping up their attacks on these new targets.
This is a particular problem because wireless devices, including smart cellular
phones and personal digital assistants (PDAs) with Internet access, were not
originally designed with security as a top priority. Now, however, wireless
security is becoming an important area of product research and development.
As in the wired world, wireless security boils down to protecting information
and preventing unauthorized system access. However, it is challenging to implement
security in small-footprint devices with low processing power and small memory
capacities and that use unreliable, low-bandwidth wireless networks.
The main goal of the seminar is to outline the basic concepts of cryptography to understand the deployment of wireless secured applications. In particular, the seminar will illustrate the "classic" security technology of VPN and PKI in the new wireless context.

CryptoNet
Founded in 1995, CryptoNet is a pioneer in the information security business
in Italy. CryptoNet provides a wide range of security solutions that sweep from
the project and the implementation of PKI, secure VPNs based on the IPSec protocol,
digital signatures and network security certification. CryptoNet solutions are
comprehensive and integrated for simplicity and customization. CryptoNet focuses
on financial services, manufacturing, telecommunications and government institutions
in Italy. CryptoNet is privately held and based in Milan with an office in Rome.

Speaker:
Mirko Tedaldi was born in Meldola (FO) in 1974. He got his laurea
degree in Computer Science Engineering at the University of Bologna in June
1999 with a thesis about information security technologies (a PKI pilot to sign
examination documents digitally.) He has been working for the CryptoNet since
October 1999 and he was involved in two big projects of IPSec VPNs for Omnitel
S.p.A. and RUPA (Rete Unitaria per la Pubblica Amministrazione). Moreover, as
consultant of Reggio Emilia Municipality, he was a member of the European S2
Sprite GUIDeS project, whose main aim has been to improve emerging practices
in the setting up of certification services, particularly within the public
sector, by providing Guidelines to set up a CA for digital signatures. At present,
he is involved in projects about PKIs, VPNs, PMIs, web authentication and authorization
as a security engineer of CryptoNet.
