- 1. Viswesvaraya Technological University, Belagavi Seminar Presentation 5G Technology and Security Under the guidance of Ranjeet Kumar Upadhyay : 1AY15EC075 Department of Electronics and Communication Engineering Acharya Institute of Technology, Soladevenahalli, Bengaluru Mrs Pranita Palsapure Assistant Professor by
- 2. 4GDrawbacks 4G drawbacks • Complex hardware. • Connectivity is still limited. • Have it’s initial glitches and bugs. • Much poorer battery life on this network. • Possibility of some interference and it cable of being attacked. • forced to buy new devices to support 4G.
- 3. evolutionof5G evolution of 5G • Started from late 2010s • Better connectivity and coverage. • It is a complete wireless communication with no limitations • Large number of accessories could be access. • Low consumption of battery. • High speed & high capacity. • Faster data transmission that of the previous generation.
- 4. attacks attacks Attack : Gaining the access of data by unauthorized user. Types of attacks: Passive attack: Data is only access by the unauthorized person but not modified the data. Active attack: Data can be modified by the 3rd person. Security attack: • Eavesdropping • Jamming • DoS AND DDoS • MITM
- 5. EavesdroppingJamming eavesdropping Jamming • tries to steal information that computers, smartphones transmit over a network. • Due to the passive nature, eavesdropping is hard to detect • Encryption of the signal is used to avoid this attack. • an intentional interference attacks on wireless network. • an attempt of making the users not possible to use network resources. • jammers work by the transmission of radio signals that disrupt communications
- 6. 4GDrawbacks DoS&DDoSMITM MITMDoS & DDoS DoS (Denial of Service) attack: One attacker. • to make a web resources unavailable to it’s users by flooding the target URL with more requests than the server can handle. DDoS (Distributed Denial of Services)attack: Thousands of requests. • typically thousands of unsuspecting zombie machines. • machine used in such attacks are collectively known as “Botnets” • a form of eavesdropping where communication between two users is monitored and modified by an unauthorized party. • Mutual authentication between the mobile device can be solution to this attack.
- 7. Security Security services 1. authentication 2. confidentiality 3. availability 4. integrity
- 8. 4GDrawbacks authentication authentication confidentiality confidentiality • a process that ensures and confirms a user’s identity. • begins when a user tries to access information. • the user must prove his access rights and identity. • protecting information from being accessed by unauthorized parties. • a set of rules that limits access to information. • consists of two aspects, i.e., data confidentiality and privacy. • Data encryption is a common method of ensuring confidentiality.
- 9. integrityintegrity integrit y availability • defined as the degree to which a service is accessible and usable to any legitimate users whenever and wherever it is requested. • it is a key performance metric in 5G. • One of the major attacks is DoS attack. • involves maintaining the consistency, accuracy and trustworthiness of data over its entire life cycle. • Data must not be changed in transit. • Integrity prevents information from being modified.
- 10. technologies technologies 1. SDN 2. HetNet 3. D2D 4. massive MIMO
- 11. SDN SDN(Software Defined Network) • a type of security model in which the information security in a computing environment is implemented, controlled and managed by security services. • all protocols- specific features are implemented in software. • Encryption and use of digital signature can be used to prevent attacks such as MITM.
- 12. HetNet HetNET (Heterogenous Network) • a network connecting computers and other devices with different OS and protocols. • HetNet achieves higher capacity, wider coverage and better performance in EE and SE. • Cross-layer cooperation scheme is purposed to tackle jamming attack. • intrusion detection techniques is introduced.
- 13. D2D D2D (Device 2 Device) • communication that enables direct communication between nearby devices. • Cryptography is applied to achieve security requirements. • Dynamic spectrum access is used to tackle jamming • Cooperation between D2D nodes is a popular way to secure the D2D communications against eavesdroppers.
- 14. massiveMIMO massive MIMO (multiple input multiple output) • method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation. • 5G Base Stations can support about a hundred ports. • Antenna numbers at the BS can significantly impact the security to avoid attacks such as jamming. • technologies such as millimetre waves is used.
- 16. • A architecture architecture • Access and mobility management function (AMF): to manage access control & mobility. • Session management function (SMF):setup and manages sessions. • Unified data management (UMF):manages subscriber data and profiles. • Policy control function (PCF): provides roaming ,mobility management and QoS. Security domains • Network access security(A):provide user interface to access the next generation core securely & protect against various attacks. • Network domain security(B):protect against attacks in the wire line networks & functions to exchange signalling data and user data in secure manner. • User domain security(C):provide mutual authentication between the user interface & next generation core.
- 17. conclusion conclusi on • advanced performance to enable many new applications. • security services provided such as authentication, availability, data confidentiality, key management and privacy have been introduced. • New technologies such as HetNet, D2D, massive MIMO, SDN.
