Security work in ETSI• 3G and GSM (via www.3gpp.org)• DECT cordless phones• TETRA – Public Service mobile• NGN – Next Generation Networks in TISPAN7

– based on 3GPP’s IMS-SIP (intrinsic resilience of IP networks)• Digital signatures• Emergency communications (see GSC11_Joint_07)• Lawful Interception (see GSC11_Joint_17)• Security workshop (January 2006, free!!)

– workshop review on www.etsi.org• White Paper: Security for ICT - the Work of ETSI (see

GSC11_Joint_18)

Algorithms

• ETSI is a world leader in creating cryptographic algorithms and protocols to prevent fraud and unauthorised access to ICT and broadcast networks, and to protect customers’ privacy

• ETSI algorithms include:– algorithms used to protect GPRS, GSM and 3GPP

communications• extremely robust in real-life situations

– Dual-Tone Multi-Frequency (DTMF) receiver algorithm for PBX and Central Office applications

• used around the world, outperforming all traditional solutions– Conditional Access for TV etc

ongoing work• Lawful Interception (see GSC11_Joint_17)

– service specific details for IP multimedia services intercept– considerations for CSP domain IP interception– service-specific details for IP delivery of PSTN/ISDN Services

interception– Technical Report on Stored Data Handover

• Smart cards– GSM SIM card standards for security, authentication etc– extended the USIM and UICC for 3G and other applications,

including access control to WLANs and for PC security functions • Electronic signatures

– supporting the development of a European electronic signature infrastructure
